# webpack-dev-server
Use [webpack](https://webpack.js.org) with a development server that provides
live reloading. This should be used for **development only**.
It uses [webpack-dev-middleware][middleware-url] under the hood, which provides
fast in-memory access to the webpack assets.

## Getting Started
First things first, install the module:
```console
npm install webpack-dev-server --save-dev
```
or
```console
yarn add -D webpack-dev-server
```
or
```console
pnpm add -D webpack-dev-server
```
_Note: While you can install and run webpack-dev-server globally, we recommend
installing it locally. webpack-dev-server will always use a local installation
over a global one._
## Usage
There are two main, recommended methods of using the module:
### With the CLI
The easiest way to use it is with the [webpack CLI](https://webpack.js.org/api/cli/). In the directory where your
`webpack.config.js` is, run:
```console
npx webpack serve
```
Following options are available with `webpack serve`:

### With NPM Scripts
NPM package.json scripts are a convenient and useful means to run locally installed
binaries without having to be concerned about their full paths. Simply define a
script as such:
```json
{
"scripts": {
"serve": "webpack serve"
}
}
```
And run the following in your terminal/console:
```console
npm run serve
```
NPM will automatically refer to the the binary in `node_modules` for you, and
execute the file or command.
### With the API
While it's recommended to run webpack-dev-server via the CLI, you may also choose to start a server via the API.
See the related [API documentation for `webpack-dev-server`](https://webpack.js.org/api/webpack-dev-server/).
### With TypeScript
If you use TypeScript in the webpack config, you'll need to properly type `devServer` property in order to avoid TS errors (e.g. `'devServer' does not exist in type 'Configuration'`). For that use either:
```ts
/// <reference path="node_modules/webpack-dev-server/types/lib/Server.d.ts"/>
import type { Configuration } from "webpack";
// Your logic
```
Or you can import the type from `webpack-dev-server`, i.e.
```ts
import type { Configuration as DevServerConfiguration } from "webpack-dev-server";
import type { Configuration } from "webpack";
const devServer: DevServerConfiguration = {};
const config: Configuration = { devServer };
// module.exports
export default config;
```
### The Result
Either method will start a server instance and begin listening for connections
from `localhost` on port `8080`.
webpack-dev-server is configured by default to support live-reload of files as
you edit your assets while the server is running.
See [**the documentation**][docs-url] for more use cases and options.
## Browser Support
While `webpack-dev-server` transpiles the client (browser) scripts to an ES5
state, the project only officially supports the _last two versions of major
browsers_. We simply don't have the resources to support every whacky
browser out there.
If you find a bug with an obscure / old browser, we would actively welcome a
Pull Request to resolve the bug.
## Support
We do our best to keep issues in the repository focused on bugs, features, and
needed modifications to the code for the module. Because of that, we ask users
with general support, "how-to", or "why isn't this working" questions to try one
of the other support channels that are available.
Your first-stop-shop for support for webpack-dev-server should be the excellent
[documentation][docs-url] for the module. If you see an opportunity for improvement
of those docs, please head over to the [webpack.js.org repo][wjo-url] and open a
pull request.
From there, we encourage users to visit the [webpack discussions][discussion-url] and
talk to the fine folks there. If your quest for answers comes up dry in chat,
head over to [StackOverflow][stack-url] and do a quick search or open a new
question. Remember; It's always much easier to answer questions that include your
`webpack.config.js` and relevant files!
If you're twitter-savvy you can tweet [#webpack][hash-url] with your question
and someone should be able to reach out and lend a hand.
If you have discovered a :bug:, have a feature suggestion, or would like to see
a modification, please feel free to create an issue on Github. _Note: The issue
template isn't optional, so please be sure not to remove it, and please fill it
out completely._

* - the state definition only support `on` and target must be declared with { target: 'nextState', actions: [] } explicitly.
* - event passed to `send` must be an object with `type` property.
* - actions implementation will be [assign action](https://xstate.js.org/docs/guides/context.html#assign-action) if you return any value.
* Do not return anything if you just want to invoke side effect.

* The goal of this custom function is to avoid installing the entire `'xstate/fsm'` package, while enabling modeling using

# Chokidar [![Weekly downloads](https://img.shields.io/npm/dw/chokidar.svg)](https://github.com/paulmillr/chokidar) [![Yearly downloads](https://img.shields.io/npm/dy/chokidar.svg)](https://github.com/paulmillr/chokidar)
> Minimal and efficient cross-platform file watching library
[![NPM](https://nodei.co/npm/chokidar.png)](https://www.npmjs.com/package/chokidar)
## Why?
Node.js `fs.watch`:
* Doesn't report filenames on MacOS.
* Doesn't report events at all when using editors like Sublime on MacOS.
* Often reports events twice.
* Emits most changes as `rename`.
* Does not provide an easy way to recursively watch file trees.
* Does not support recursive watching on Linux.
Node.js `fs.watchFile`:
* Almost as bad at event handling.
* Also does not provide any recursive watching.
* Results in high CPU utilization.
Chokidar resolves these problems.
Initially made for **[Brunch](https://brunch.io/)** (an ultra-swift web app build tool), it is now used in
[Microsoft's Visual Studio Code](https://github.com/microsoft/vscode),
[gulp](https://github.com/gulpjs/gulp/),
[karma](https://karma-runner.github.io/),
[PM2](https://github.com/Unitech/PM2),
[browserify](http://browserify.org/),
[webpack](https://webpack.github.io/),
[BrowserSync](https://www.browsersync.io/),
and [many others](https://www.npmjs.com/browse/depended/chokidar).
It has proven itself in production environments.
Version 3 is out! Check out our blog post about it: [Chokidar 3: How to save 32TB of traffic every week](https://paulmillr.com/posts/chokidar-3-save-32tb-of-traffic/)
## How?
Chokidar does still rely on the Node.js core `fs` module, but when using
`fs.watch` and `fs.watchFile` for watching, it normalizes the events it
receives, often checking for truth by getting file stats and/or dir contents.
On MacOS, chokidar by default uses a native extension exposing the Darwin
`FSEvents` API. This provides very efficient recursive watching compared with
implementations like `kqueue` available on most \*nix platforms. Chokidar still
does have to do some work to normalize the events received that way as well.
On most other platforms, the `fs.watch`-based implementation is the default, which
avoids polling and keeps CPU usage down. Be advised that chokidar will initiate
watchers recursively for everything within scope of the paths that have been
specified, so be judicious about not wasting system resources by watching much
more than needed.
## Getting started
Install with npm:
```sh
npm install chokidar
```
Then `require` and use it in your code:
```javascript
const chokidar = require('chokidar');
// One-liner for current directory
chokidar.watch('.').on('all', (event, path) => {
console.log(event, path);
});
```
## API
```javascript
// Example of a more typical implementation structure
// Initialize watcher.
const watcher = chokidar.watch('file, dir, glob, or array', {
ignored: /(^|[\/\\])\../, // ignore dotfiles
persistent: true
});
// Something to use when events are received.
const log = console.log.bind(console);
// Add event listeners.
watcher
.on('add', path => log(`File ${path} has been added`))
.on('change', path => log(`File ${path} has been changed`))
.on('unlink', path => log(`File ${path} has been removed`));
// More possible events.
watcher
.on('addDir', path => log(`Directory ${path} has been added`))
.on('unlinkDir', path => log(`Directory ${path} has been removed`))
.on('error', error => log(`Watcher error: ${error}`))
.on('ready', () => log('Initial scan complete. Ready for changes'))
.on('raw', (event, path, details) => { // internal
log('Raw event info:', event, path, details);
});
// 'add', 'addDir' and 'change' events also receive stat() results as second
// argument when available: https://nodejs.org/api/fs.html#fs_class_fs_stats
watcher.on('change', (path, stats) => {
if (stats) console.log(`File ${path} changed size to ${stats.size}`);
});
// Watch new files.
watcher.add('new-file');
watcher.add(['new-file-2', 'new-file-3', '**/other-file*']);
// Get list of actual paths being watched on the filesystem
var watchedPaths = watcher.getWatched();
// Un-watch some files.
await watcher.unwatch('new-file*');
// Stop watching.
// The method is async!
watcher.close().then(() => console.log('closed'));
// Full list of options. See below for descriptions.
// Do not use this example!
chokidar.watch('file', {
persistent: true,
ignored: '*.txt',
ignoreInitial: false,
followSymlinks: true,
cwd: '.',
disableGlobbing: false,
usePolling: false,
interval: 100,
binaryInterval: 300,
alwaysStat: false,
depth: 99,
awaitWriteFinish: {
stabilityThreshold: 2000,
pollInterval: 100
},
ignorePermissionErrors: false,
atomic: true // or a custom 'atomicity delay', in milliseconds (default 100)
});
```
`chokidar.watch(paths, [options])`
* `paths` (string or array of strings). Paths to files, dirs to be watched
recursively, or glob patterns.
- Note: globs must not contain windows separators (`\`),
because that's how they work by the standard —
you'll need to replace them with forward slashes (`/`).
- Note 2: for additional glob documentation, check out low-level
library: [picomatch](https://github.com/micromatch/picomatch).
* `options` (object) Options object as defined below:
#### Persistence
* `persistent` (default: `true`). Indicates whether the process
should continue to run as long as files are being watched. If set to
`false` when using `fsevents` to watch, no more events will be emitted
after `ready`, even if the process continues to run.
#### Path filtering
* `ignored` ([anymatch](https://github.com/es128/anymatch)-compatible definition)
Defines files/paths to be ignored. The whole relative or absolute path is
tested, not just filename. If a function with two arguments is provided, it
gets called twice per path - once with a single argument (the path), second
time with two arguments (the path and the
[`fs.Stats`](https://nodejs.org/api/fs.html#fs_class_fs_stats)
object of that path).
* `ignoreInitial` (default: `false`). If set to `false` then `add`/`addDir` events are also emitted for matching paths while
instantiating the watching as chokidar discovers these file paths (before the `ready` event).
* `followSymlinks` (default: `true`). When `false`, only the
symlinks themselves will be watched for changes instead of following
the link references and bubbling events through the link's path.
* `cwd` (no default). The base directory from which watch `paths` are to be
derived. Paths emitted with events will be relative to this.
* `disableGlobbing` (default: `false`). If set to `true` then the strings passed to `.watch()` and `.add()` are treated as
literal path names, even if they look like globs.
#### Performance
* `usePolling` (default: `false`).
Whether to use fs.watchFile (backed by polling), or fs.watch. If polling
leads to high CPU utilization, consider setting this to `false`. It is
typically necessary to **set this to `true` to successfully watch files over
a network**, and it may be necessary to successfully watch files in other
non-standard situations. Setting to `true` explicitly on MacOS overrides the
`useFsEvents` default. You may also set the CHOKIDAR_USEPOLLING env variable
to true (1) or false (0) in order to override this option.
* _Polling-specific settings_ (effective when `usePolling: true`)
* `interval` (default: `100`). Interval of file system polling, in milliseconds. You may also
set the CHOKIDAR_INTERVAL env variable to override this option.
* `binaryInterval` (default: `300`). Interval of file system
polling for binary files.
([see list of binary extensions](https://github.com/sindresorhus/binary-extensions/blob/master/binary-extensions.json))
* `useFsEvents` (default: `true` on MacOS). Whether to use the
`fsevents` watching interface if available. When set to `true` explicitly
and `fsevents` is available this supercedes the `usePolling` setting. When
set to `false` on MacOS, `usePolling: true` becomes the default.
* `alwaysStat` (default: `false`). If relying upon the
[`fs.Stats`](https://nodejs.org/api/fs.html#fs_class_fs_stats)
object that may get passed with `add`, `addDir`, and `change` events, set
this to `true` to ensure it is provided even in cases where it wasn't
already available from the underlying watch events.
* `depth` (default: `undefined`). If set, limits how many levels of
subdirectories will be traversed.
* `awaitWriteFinish` (default: `false`).
By default, the `add` event will fire when a file first appears on disk, before
the entire file has been written. Furthermore, in some cases some `change`
events will be emitted while the file is being written. In some cases,
especially when watching for large files there will be a need to wait for the
write operation to finish before responding to a file creation or modification.
Setting `awaitWriteFinish` to `true` (or a truthy value) will poll file size,
holding its `add` and `change` events until the size does not change for a
configurable amount of time. The appropriate duration setting is heavily
dependent on the OS and hardware. For accurate detection this parameter should
be relatively high, making file watching much less responsive.
Use with caution.
* *`options.awaitWriteFinish` can be set to an object in order to adjust
timing params:*
* `awaitWriteFinish.stabilityThreshold` (default: 2000). Amount of time in
milliseconds for a file size to remain constant before emitting its event.
* `awaitWriteFinish.pollInterval` (default: 100). File size polling interval, in milliseconds.
#### Errors
* `ignorePermissionErrors` (default: `false`). Indicates whether to watch files
that don't have read permissions if possible. If watching fails due to `EPERM`
or `EACCES` with this set to `true`, the errors will be suppressed silently.
* `atomic` (default: `true` if `useFsEvents` and `usePolling` are `false`).
Automatically filters out artifacts that occur when using editors that use
"atomic writes" instead of writing directly to the source file. If a file is
re-added within 100 ms of being deleted, Chokidar emits a `change` event
rather than `unlink` then `add`. If the default of 100 ms does not work well
for you, you can override it by setting `atomic` to a custom value, in
milliseconds.
### Methods & Events
`chokidar.watch()` produces an instance of `FSWatcher`. Methods of `FSWatcher`:
* `.add(path / paths)`: Add files, directories, or glob patterns for tracking.
Takes an array of strings or just one string.
* `.on(event, callback)`: Listen for an FS event.
Available events: `add`, `addDir`, `change`, `unlink`, `unlinkDir`, `ready`,
`raw`, `error`.
Additionally `all` is available which gets emitted with the underlying event
name and path for every event other than `ready`, `raw`, and `error`. `raw` is internal, use it carefully.
* `.unwatch(path / paths)`: Stop watching files, directories, or glob patterns.
Takes an array of strings or just one string.
* `.close()`: **async** Removes all listeners from watched files. Asynchronous, returns Promise. Use with `await` to ensure bugs don't happen.
* `.getWatched()`: Returns an object representing all the paths on the file
system being watched by this `FSWatcher` instance. The object's keys are all the
directories (using absolute paths unless the `cwd` option was used), and the
values are arrays of the names of the items contained in each directory.
## CLI
If you need a CLI interface for your file watching, check out
[chokidar-cli](https://github.com/open-cli-tools/chokidar-cli), allowing you to
execute a command on each change, or get a stdio stream of change events.
## Install Troubleshooting
* `npm WARN optional dep failed, continuing fsevents@n.n.n`
* This message is normal part of how `npm` handles optional dependencies and is
not indicative of a problem. Even if accompanied by other related error messages,
Chokidar should function properly.
* `TypeError: fsevents is not a constructor`
* Update chokidar by doing `rm -rf node_modules package-lock.json yarn.lock && npm install`, or update your dependency that uses chokidar.
* Chokidar is producing `ENOSP` error on Linux, like this:
* `bash: cannot set terminal process group (-1): Inappropriate ioctl for device bash: no job control in this shell`
`Error: watch /home/ ENOSPC`
* This means Chokidar ran out of file handles and you'll need to increase their count by executing the following command in Terminal:
`echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p`
## Changelog
For more detailed changelog, see [`full_changelog.md`](.github/full_changelog.md).
- **v3.5 (Jan 6, 2021):** Support for ARM Macs with Apple Silicon. Fixes for deleted symlinks.
- **v3.4 (Apr 26, 2020):** Support for directory-based symlinks. Fixes for macos file replacement.
- **v3.3 (Nov 2, 2019):** `FSWatcher#close()` method became async. That fixes IO race conditions related to close method.
- **v3.2 (Oct 1, 2019):** Improve Linux RAM usage by 50%. Race condition fixes. Windows glob fixes. Improve stability by using tight range of dependency versions.
- **v3.1 (Sep 16, 2019):** dotfiles are no longer filtered out by default. Use `ignored` option if needed. Improve initial Linux scan time by 50%.
- **v3 (Apr 30, 2019):** massive CPU & RAM consumption improvements; reduces deps / package size by a factor of 17x and bumps Node.js requirement to v8.16 and higher.
- **v2 (Dec 29, 2017):** Globs are now posix-style-only; without windows support. Tons of bugfixes.
- **v1 (Apr 7, 2015):** Glob support, symlink support, tons of bugfixes. Node 0.8+ is supported
- **v0.1 (Apr 20, 2012):** Initial release, extracted from [Brunch](https://github.com/brunch/brunch/blob/9847a065aea300da99bd0753f90354cde9de1261/src/helpers.coffee#L66)
## Also
Why was chokidar named this way? What's the meaning behind it?
>Chowkidar is a transliteration of a Hindi word meaning 'watchman, gatekeeper', चौकीदार. This ultimately comes from Sanskrit _ चतुष्क_ (crossway, quadrangle, consisting-of-four). This word is also used in other languages like Urdu as (چوکیدار) which is widely used in Pakistan and India.

# glob-parent
[![NPM version][npm-image]][npm-url] [![Downloads][downloads-image]][npm-url] [![Azure Pipelines Build Status][azure-pipelines-image]][azure-pipelines-url] [![Travis Build Status][travis-image]][travis-url] [![AppVeyor Build Status][appveyor-image]][appveyor-url] [![Coveralls Status][coveralls-image]][coveralls-url] [![Gitter chat][gitter-image]][gitter-url]
Extract the non-magic parent path from a glob string.
## Usage
```js
var globParent = require('glob-parent');
globParent('path/to/*.js'); // 'path/to'
globParent('/root/path/to/*.js'); // '/root/path/to'
globParent('/*.js'); // '/'
globParent('*.js'); // '.'
globParent('**/*.js'); // '.'
globParent('path/{to,from}'); // 'path'
globParent('path/!(to|from)'); // 'path'
globParent('path/?(to|from)'); // 'path'
globParent('path/+(to|from)'); // 'path'
globParent('path/*(to|from)'); // 'path'
globParent('path/@(to|from)'); // 'path'
globParent('path/**/*'); // 'path'
// if provided a non-glob path, returns the nearest dir
globParent('path/foo/bar.js'); // 'path/foo'
globParent('path/foo/'); // 'path/foo'
globParent('path/foo'); // 'path' (see issue #3 for details)
```
## API
### `globParent(maybeGlobString, [options])`
Takes a string and returns the part of the path before the glob begins. Be aware of Escaping rules and Limitations below.
#### options
```js
{
// Disables the automatic conversion of slashes for Windows
flipBackslashes: true
}
```
## Escaping
The following characters have special significance in glob patterns and must be escaped if you want them to be treated as regular path characters:
- `?` (question mark) unless used as a path segment alone
- `*` (asterisk)
- `|` (pipe)
- `(` (opening parenthesis)
- `)` (closing parenthesis)
- `{` (opening curly brace)
- `}` (closing curly brace)
- `[` (opening bracket)
- `]` (closing bracket)
**Example**
```js
globParent('foo/[bar]/') // 'foo'
globParent('foo/\\[bar]/') // 'foo/[bar]'
```
## Limitations
### Braces & Brackets
This library attempts a quick and imperfect method of determining which path
parts have glob magic without fully parsing/lexing the pattern. There are some
advanced use cases that can trip it up, such as nested braces where the outer
pair is escaped and the inner one contains a path separator. If you find
yourself in the unlikely circumstance of being affected by this or need to
ensure higher-fidelity glob handling in your library, it is recommended that you
pre-process your input with [expand-braces] and/or [expand-brackets].
### Windows
Backslashes are not valid path separators for globs. If a path with backslashes
is provided anyway, for simple cases, glob-parent will replace the path
separator for you and return the non-glob parent path (now with
forward-slashes, which are still valid as Windows path separators).
This cannot be used in conjunction with escape characters.
```js
// BAD
globParent('C:\\Program Files \\(x86\\)\\*.ext') // 'C:/Program Files /(x86/)'
// GOOD
globParent('C:/Program Files\\(x86\\)/*.ext') // 'C:/Program Files (x86)'
```
If you are using escape characters for a pattern without path parts (i.e.
relative to `cwd`), prefix with `./` to avoid confusing glob-parent.
```js
// BAD
globParent('foo \\[bar]') // 'foo '
globParent('foo \\[bar]*') // 'foo '
// GOOD
globParent('./foo \\[bar]') // 'foo [bar]'
globParent('./foo \\[bar]*') // '.'
```

## ⚠️ Note <!-- omit in toc -->
This page is showing documentation for version v2.x.x ([release notes](https://github.com/chimurai/http-proxy-middleware/releases))
If you're looking for v0.x documentation. Go to:
https://github.com/chimurai/http-proxy-middleware/tree/v0.21.0#readme
## TL;DR <!-- omit in toc -->
Proxy `/api` requests to `http://www.example.org`
```javascript
// javascript
const express = require('express');
const { createProxyMiddleware } = require('http-proxy-middleware');
const app = express();
app.use('/api', createProxyMiddleware({ target: 'http://www.example.org', changeOrigin: true }));
app.listen(3000);
// http://localhost:3000/api/foo/bar -> http://www.example.org/api/foo/bar
```
```typescript
// typescript
import * as express from 'express';
import { createProxyMiddleware, Filter, Options, RequestHandler } from 'http-proxy-middleware';
const app = express();
app.use('/api', createProxyMiddleware({ target: 'http://www.example.org', changeOrigin: true }));
app.listen(3000);
// http://localhost:3000/api/foo/bar -> http://www.example.org/api/foo/bar
```
_All_ `http-proxy` [options](https://github.com/nodejitsu/node-http-proxy#options) can be used, along with some extra `http-proxy-middleware` [options](#options).
:bulb: **Tip:** Set the option `changeOrigin` to `true` for [name-based virtual hosted sites](http://en.wikipedia.org/wiki/Virtual_hosting#Name-based).

## Install
```bash
$ npm install --save-dev http-proxy-middleware
```
## Core concept
Proxy middleware configuration.
#### createProxyMiddleware([context,] config)
```javascript
const { createProxyMiddleware } = require('http-proxy-middleware');
const apiProxy = createProxyMiddleware('/api', { target: 'http://www.example.org' });
// \____/ \_____________________________/
// | |
// context options
// 'apiProxy' is now ready to be used as middleware in a server.
```
- **context**: Determine which requests should be proxied to the target host.
(more on [context matching](#context-matching))
- **options.target**: target host to proxy to. _(protocol + host)_
(full list of [`http-proxy-middleware` configuration options](#options))
#### createProxyMiddleware(uri [, config])
```javascript
// shorthand syntax for the example above:
const apiProxy = createProxyMiddleware('http://www.example.org/api');
```
More about the [shorthand configuration](#shorthand).
## Example
An example with `express` server.
```javascript
// include dependencies
const express = require('express');
const { createProxyMiddleware } = require('http-proxy-middleware');
// proxy middleware options
/** @type {import('http-proxy-middleware/dist/types').Options} */
const options = {
target: 'http://www.example.org', // target host
changeOrigin: true, // needed for virtual hosted sites
ws: true, // proxy websockets
pathRewrite: {
'^/api/old-path': '/api/new-path', // rewrite path
'^/api/remove/path': '/path', // remove base path
},
router: {
// when request.headers.host == 'dev.localhost:3000',
// override target 'http://www.example.org' to 'http://localhost:8000'
'dev.localhost:3000': 'http://localhost:8000',
},
};
// create the proxy (without context)
const exampleProxy = createProxyMiddleware(options);
// mount `exampleProxy` in web server
const app = express();
app.use('/api', exampleProxy);
app.listen(3000);
```
## Context matching
Providing an alternative way to decide which requests should be proxied; In case you are not able to use the server's [`path` parameter](http://expressjs.com/en/4x/api.html#app.use) to mount the proxy or when you need more flexibility.
[RFC 3986 `path`](https://tools.ietf.org/html/rfc3986#section-3.3) is used for context matching.
```ascii
foo://example.com:8042/over/there?name=ferret#nose
\_/ \______________/\_________/ \_________/ \__/
| | | | |
scheme authority path query fragment
```
- **path matching**
- `createProxyMiddleware({...})` - matches any path, all requests will be proxied.
- `createProxyMiddleware('/', {...})` - matches any path, all requests will be proxied.
- `createProxyMiddleware('/api', {...})` - matches paths starting with `/api`
- **multiple path matching**
- `createProxyMiddleware(['/api', '/ajax', '/someotherpath'], {...})`
- **wildcard path matching**
For fine-grained control you can use wildcard matching. Glob pattern matching is done by _micromatch_. Visit [micromatch](https://www.npmjs.com/package/micromatch) or [glob](https://www.npmjs.com/package/glob) for more globbing examples.
- `createProxyMiddleware('**', {...})` matches any path, all requests will be proxied.
- `createProxyMiddleware('**/*.html', {...})` matches any path which ends with `.html`
- `createProxyMiddleware('/*.html', {...})` matches paths directly under path-absolute
- `createProxyMiddleware('/api/**/*.html', {...})` matches requests ending with `.html` in the path of `/api`
- `createProxyMiddleware(['/api/**', '/ajax/**'], {...})` combine multiple patterns
- `createProxyMiddleware(['/api/**', '!**/bad.json'], {...})` exclusion
**Note**: In multiple path matching, you cannot use string paths and wildcard paths together.
- **custom matching**
For full control you can provide a custom function to determine which requests should be proxied or not.
```javascript
/**
* @return {Boolean}

```
## Options
### http-proxy-middleware options
- **option.pathRewrite**: object/function, rewrite target's url path. Object-keys will be used as _RegExp_ to match paths.
```javascript
// rewrite path
pathRewrite: {'^/old/api' : '/new/api'}
// remove path
pathRewrite: {'^/remove/api' : ''}
// add base path
pathRewrite: {'^/' : '/basepath/'}
// custom rewriting
pathRewrite: function (path, req) { return path.replace('/api', '/base/api') }
// custom rewriting, returning Promise
pathRewrite: async function (path, req) {
const should_add_something = await httpRequestToDecideSomething(path);
if (should_add_something) path += "something";
return path;
}
```
- **option.router**: object/function, re-target `option.target` for specific requests.
```javascript
// Use `host` and/or `path` to match requests. First match will be used.
// The order of the configuration matters.
router: {
'integration.localhost:3000' : 'http://localhost:8001', // host only
'staging.localhost:3000' : 'http://localhost:8002', // host only
'localhost:3000/api' : 'http://localhost:8003', // host + path
'/rest' : 'http://localhost:8004' // path only
}
// Custom router function (string target)
router: function(req) {
return 'http://localhost:8004';
}
// Custom router function (target object)
router: function(req) {
return {
protocol: 'https:', // The : is required
host: 'localhost',
port: 8004
};
}
// Asynchronous router function which returns promise
router: async function(req) {
const url = await doSomeIO();
return url;
}
```
- **option.logLevel**: string, ['debug', 'info', 'warn', 'error', 'silent']. Default: `'info'`
- **option.logProvider**: function, modify or replace log provider. Default: `console`.
```javascript
// simple replace
function logProvider(provider) {
// replace the default console log provider.
return require('winston');
}
```
```javascript
// verbose replacement
function logProvider(provider) {
const logger = new (require('winston').Logger)();
const myCustomProvider = {
log: logger.log,
debug: logger.debug,
info: logger.info,
warn: logger.warn,
error: logger.error,
};
return myCustomProvider;
}
```
### http-proxy events
Subscribe to [http-proxy events](https://github.com/nodejitsu/node-http-proxy#listening-for-proxy-events):
- **option.onError**: function, subscribe to http-proxy's `error` event for custom error handling.
```javascript
function onError(err, req, res, target) {
res.writeHead(500, {
'Content-Type': 'text/plain',
});
res.end('Something went wrong. And we are reporting a custom error message.');
}
```
- **option.onProxyRes**: function, subscribe to http-proxy's `proxyRes` event.
```javascript
function onProxyRes(proxyRes, req, res) {
proxyRes.headers['x-added'] = 'foobar'; // add new header to response
delete proxyRes.headers['x-removed']; // remove header from response
}
```
- **option.onProxyReq**: function, subscribe to http-proxy's `proxyReq` event.
```javascript
function onProxyReq(proxyReq, req, res) {
// add custom header to request
proxyReq.setHeader('x-added', 'foobar');
// or log the req
}
```
- **option.onProxyReqWs**: function, subscribe to http-proxy's `proxyReqWs` event.
```javascript
function onProxyReqWs(proxyReq, req, socket, options, head) {
// add custom header
proxyReq.setHeader('X-Special-Proxy-Header', 'foobar');
}
```
- **option.onOpen**: function, subscribe to http-proxy's `open` event.
```javascript
function onOpen(proxySocket) {
// listen for messages coming FROM the target here
proxySocket.on('data', hybridParseAndLogMessage);
}
```
- **option.onClose**: function, subscribe to http-proxy's `close` event.
```javascript
function onClose(res, socket, head) {
// view disconnected websocket connections
console.log('Client disconnected');
}
```
### http-proxy options
The following options are provided by the underlying [http-proxy](https://github.com/nodejitsu/node-http-proxy#options) library.
- **option.target**: url string to be parsed with the url module
- **option.forward**: url string to be parsed with the url module
- **option.agent**: object to be passed to http(s).request (see Node's [https agent](http://nodejs.org/api/https.html#https_class_https_agent) and [http agent](http://nodejs.org/api/http.html#http_class_http_agent) objects)
- **option.ssl**: object to be passed to https.createServer()
- **option.ws**: true/false: if you want to proxy websockets
- **option.xfwd**: true/false, adds x-forward headers
- **option.secure**: true/false, if you want to verify the SSL Certs
- **option.toProxy**: true/false, passes the absolute URL as the `path` (useful for proxying to proxies)
- **option.prependPath**: true/false, Default: true - specify whether you want to prepend the target's path to the proxy path
- **option.ignorePath**: true/false, Default: false - specify whether you want to ignore the proxy path of the incoming request (note: you will have to append / manually if required).
- **option.localAddress** : Local interface string to bind for outgoing connections
- **option.changeOrigin**: true/false, Default: false - changes the origin of the host header to the target URL
- **option.preserveHeaderKeyCase**: true/false, Default: false - specify whether you want to keep letter case of response header key
- **option.auth** : Basic authentication i.e. 'user:password' to compute an Authorization header.
- **option.hostRewrite**: rewrites the location hostname on (301/302/307/308) redirects.
- **option.autoRewrite**: rewrites the location host/port on (301/302/307/308) redirects based on requested host/port. Default: false.
- **option.protocolRewrite**: rewrites the location protocol on (301/302/307/308) redirects to 'http' or 'https'. Default: null.
- **option.cookieDomainRewrite**: rewrites domain of `set-cookie` headers. Possible values:
- `false` (default): disable cookie rewriting
- String: new domain, for example `cookieDomainRewrite: "new.domain"`. To remove the domain, use `cookieDomainRewrite: ""`.
- Object: mapping of domains to new domains, use `"*"` to match all domains.
For example keep one domain unchanged, rewrite one domain and remove other domains:
```json
cookieDomainRewrite: {
"unchanged.domain": "unchanged.domain",
"old.domain": "new.domain",
"*": ""
}
```
- **option.cookiePathRewrite**: rewrites path of `set-cookie` headers. Possible values:
- `false` (default): disable cookie rewriting
- String: new path, for example `cookiePathRewrite: "/newPath/"`. To remove the path, use `cookiePathRewrite: ""`. To set path to root use `cookiePathRewrite: "/"`.
- Object: mapping of paths to new paths, use `"*"` to match all paths.
For example, to keep one path unchanged, rewrite one path and remove other paths:
```json
cookiePathRewrite: {
"/unchanged.path/": "/unchanged.path/",
"/old.path/": "/new.path/",
"*": ""
}
```
- **option.headers**: object, adds [request headers](https://en.wikipedia.org/wiki/List_of_HTTP_header_fields#Request_fields). (Example: `{host:'www.example.org'}`)
- **option.proxyTimeout**: timeout (in millis) when proxy receives no response from target
- **option.timeout**: timeout (in millis) for incoming requests
- **option.followRedirects**: true/false, Default: false - specify whether you want to follow redirects
- **option.selfHandleResponse** true/false, if set to true, none of the webOutgoing passes are called and it's your responsibility to appropriately return the response by listening and acting on the `proxyRes` event
- **option.buffer**: stream of data to send as the request body. Maybe you have some middleware that consumes the request stream before proxying it on e.g. If you read the body of a request into a field called 'req.rawbody' you could restream this field in the buffer option:
```javascript
'use strict';
const streamify = require('stream-array');
const HttpProxy = require('http-proxy');
const proxy = new HttpProxy();
module.exports = (req, res, next) => {
proxy.web(
req,
res,
{
target: 'http://localhost:4003/',
buffer: streamify(req.rawBody),
},
next
);
};
```
## Shorthand
Use the shorthand syntax when verbose configuration is not needed. The `context` and `option.target` will be automatically configured when shorthand is used. Options can still be used if needed.
```javascript
createProxyMiddleware('http://www.example.org:8000/api');
// createProxyMiddleware('/api', {target: 'http://www.example.org:8000'});
createProxyMiddleware('http://www.example.org:8000/api/books/*/**.json');
// createProxyMiddleware('/api/books/*/**.json', {target: 'http://www.example.org:8000'});
createProxyMiddleware('http://www.example.org:8000/api', { changeOrigin: true });
// createProxyMiddleware('/api', {target: 'http://www.example.org:8000', changeOrigin: true});
```
### app.use(path, proxy)
If you want to use the server's `app.use` `path` parameter to match requests;
Create and mount the proxy without the http-proxy-middleware `context` parameter:
```javascript
app.use('/api', createProxyMiddleware({ target: 'http://www.example.org', changeOrigin: true }));
```
`app.use` documentation:
- express: http://expressjs.com/en/4x/api.html#app.use
- connect: https://github.com/senchalabs/connect#mount-middleware
- polka: https://github.com/lukeed/polka#usebase-fn
## WebSocket
```javascript
// verbose api
createProxyMiddleware('/', { target: 'http://echo.websocket.org', ws: true });
// shorthand
createProxyMiddleware('http://echo.websocket.org', { ws: true });
// shorter shorthand
createProxyMiddleware('ws://echo.websocket.org');
```
### External WebSocket upgrade
In the previous WebSocket examples, http-proxy-middleware relies on a initial http request in order to listen to the http `upgrade` event. If you need to proxy WebSockets without the initial http request, you can subscribe to the server's http `upgrade` event manually.
```javascript
const wsProxy = createProxyMiddleware('ws://echo.websocket.org', { changeOrigin: true });
const app = express();
app.use(wsProxy);
const server = app.listen(3000);
server.on('upgrade', wsProxy.upgrade); // <-- subscribe to http 'upgrade'
```
## Intercept and manipulate requests
Intercept requests from downstream by defining `onProxyReq` in `createProxyMiddleware`.
Currently the only pre-provided request interceptor is `fixRequestBody`, which is used to fix proxied POST requests when `bodyParser` is applied before this middleware.
Example:
```javascript
const { createProxyMiddleware, fixRequestBody } = require('http-proxy-middleware');
const proxy = createProxyMiddleware({
/**
* Fix bodyParser
**/
onProxyReq: fixRequestBody,
});
```
## Intercept and manipulate responses
Intercept responses from upstream with `responseInterceptor`. (Make sure to set `selfHandleResponse: true`)
Responses which are compressed with `brotli`, `gzip` and `deflate` will be decompressed automatically. The response will be returned as `buffer` ([docs](https://nodejs.org/api/buffer.html)) which you can manipulate.
With `buffer`, response manipulation is not limited to text responses (html/css/js, etc...); image manipulation will be possible too. ([example](https://github.com/chimurai/http-proxy-middleware/blob/master/recipes/response-interceptor.md#manipulate-image-response))
NOTE: `responseInterceptor` disables streaming of target's response.
Example:
```javascript
const { createProxyMiddleware, responseInterceptor } = require('http-proxy-middleware');
const proxy = createProxyMiddleware({
/**
* IMPORTANT: avoid res.end being called automatically
**/
selfHandleResponse: true, // res.end() will be called internally by responseInterceptor()
/**
* Intercept response and replace 'Hello' with 'Goodbye'
**/
onProxyRes: responseInterceptor(async (responseBuffer, proxyRes, req, res) => {
const response = responseBuffer.toString('utf8'); // convert buffer to string
return response.replace('Hello', 'Goodbye'); // manipulate response and return the result
}),
});
```

<strong>Blazing fast and accurate glob matcher written in JavaScript.</strong></br>
<em>No dependencies and full support for standard and extended Bash glob features, including braces, extglobs, POSIX brackets, and regular expressions.</em>
</p>
<br>
<br>
## Why picomatch?
* **Lightweight** - No dependencies
* **Minimal** - Tiny API surface. Main export is a function that takes a glob pattern and returns a matcher function.
* **Fast** - Loads in about 2ms (that's several times faster than a [single frame of a HD movie](http://www.endmemo.com/sconvert/framespersecondframespermillisecond.php) at 60fps)
* **Performant** - Use the returned matcher function to speed up repeat matching (like when watching files)
* **Accurate matching** - Using wildcards (`*` and `?`), globstars (`**`) for nested directories, [advanced globbing](#advanced-globbing) with extglobs, braces, and POSIX brackets, and support for escaping special characters with `\` or quotes.
* **Well tested** - Thousands of unit tests

## Install
Install with [npm](https://www.npmjs.com/):
```sh
npm install --save picomatch
```
<br>
## Usage
The main export is a function that takes a glob pattern and an options object and returns a function for matching strings.
```js
const pm = require('picomatch');
const isMatch = pm('*.js');
console.log(isMatch('abcd')); //=> false
console.log(isMatch('a.js')); //=> true
console.log(isMatch('a.md')); //=> false
console.log(isMatch('a/b.js')); //=> false
```
<br>
## API
### [picomatch](lib/picomatch.js#L32)
Creates a matcher function from one or more glob patterns. The returned function takes a string to match as its first argument, and returns true if the string is a match. The returned matcher function also takes a boolean as the second argument that, when true, returns an object with additional information.
**Params**
* `globs` **{String|Array}**: One or more glob patterns.
* `options` **{Object=}**
* `returns` **{Function=}**: Returns a matcher function.
**Example**
```js
const picomatch = require('picomatch');
// picomatch(glob[, options]);
const isMatch = picomatch('*.!(*a)');
console.log(isMatch('a.a')); //=> false
console.log(isMatch('a.b')); //=> true
```
### [.test](lib/picomatch.js#L117)
Test `input` with the given `regex`. This is used by the main `picomatch()` function to test the input string.
**Params**
* `input` **{String}**: String to test.
* `regex` **{RegExp}**
* `returns` **{Object}**: Returns an object with matching info.
**Example**
```js
const picomatch = require('picomatch');
// picomatch.test(input, regex[, options]);
console.log(picomatch.test('foo/bar', /^(?:([^/]*?)\/([^/]*?))$/));
// { isMatch: true, match: [ 'foo/', 'foo', 'bar' ], output: 'foo/bar' }
```
### [.matchBase](lib/picomatch.js#L161)
Match the basename of a filepath.
**Params**
* `input` **{String}**: String to test.
* `glob` **{RegExp|String}**: Glob pattern or regex created by [.makeRe](#makeRe).
* `returns` **{Boolean}**
**Example**
```js
const picomatch = require('picomatch');
// picomatch.matchBase(input, glob[, options]);
console.log(picomatch.matchBase('foo/bar.js', '*.js'); // true
```
### [.isMatch](lib/picomatch.js#L183)
Returns true if **any** of the given glob `patterns` match the specified `string`.
**Params**
* **{String|Array}**: str The string to test.
* **{String|Array}**: patterns One or more glob patterns to use for matching.
* **{Object}**: See available [options](#options).
* `returns` **{Boolean}**: Returns true if any patterns match `str`
**Example**
```js
const picomatch = require('picomatch');
// picomatch.isMatch(string, patterns[, options]);
console.log(picomatch.isMatch('a.a', ['b.*', '*.a'])); //=> true
console.log(picomatch.isMatch('a.a', 'b.*')); //=> false
```
### [.parse](lib/picomatch.js#L199)
Parse a glob pattern to create the source string for a regular expression.
**Params**
* `pattern` **{String}**
* `options` **{Object}**
* `returns` **{Object}**: Returns an object with useful properties and output to be used as a regex source string.
**Example**
```js
const picomatch = require('picomatch');
const result = picomatch.parse(pattern[, options]);
```
### [.scan](lib/picomatch.js#L231)
Scan a glob pattern to separate the pattern into segments.
**Params**
* `input` **{String}**: Glob pattern to scan.
* `options` **{Object}**
* `returns` **{Object}**: Returns an object with
**Example**
```js
const picomatch = require('picomatch');
// picomatch.scan(input[, options]);
const result = picomatch.scan('!./foo/*.js');
console.log(result);
{ prefix: '!./',
input: '!./foo/*.js',
start: 3,
base: 'foo',
glob: '*.js',
isBrace: false,
isBracket: false,
isGlob: true,
isExtglob: false,
isGlobstar: false,
negated: true }
```
### [.compileRe](lib/picomatch.js#L245)
Compile a regular expression from the `state` object returned by the
[parse()](#parse) method.
**Params**
* `state` **{Object}**
* `options` **{Object}**
* `returnOutput` **{Boolean}**: Intended for implementors, this argument allows you to return the raw output from the parser.
* `returnState` **{Boolean}**: Adds the state to a `state` property on the returned regex. Useful for implementors and debugging.
* `returns` **{RegExp}**
### [.makeRe](lib/picomatch.js#L286)
Create a regular expression from a parsed glob pattern.
**Params**
* `state` **{String}**: The object returned from the `.parse` method.
* `options` **{Object}**
* `returnOutput` **{Boolean}**: Implementors may use this argument to return the compiled output, instead of a regular expression. This is not exposed on the options to prevent end-users from mutating the result.
* `returnState` **{Boolean}**: Implementors may use this argument to return the state from the parsed glob with the returned regular expression.
* `returns` **{RegExp}**: Returns a regex created from the given pattern.
**Example**
```js
const picomatch = require('picomatch');
const state = picomatch.parse('*.js');
// picomatch.compileRe(state[, options]);
console.log(picomatch.compileRe(state));
//=> /^(?:(?!\.)(?=.)[^/]*?\.js)$/
```
### [.toRegex](lib/picomatch.js#L321)
Create a regular expression from the given regex source string.
**Params**
* `source` **{String}**: Regular expression source string.
* `options` **{Object}**
* `returns` **{RegExp}**
**Example**
```js
const picomatch = require('picomatch');
// picomatch.toRegex(source[, options]);
const { output } = picomatch.parse('*.js');
console.log(picomatch.toRegex(output));
//=> /^(?:(?!\.)(?=.)[^/]*?\.js)$/
```
<br>
## Options
### Picomatch options
The following options may be used with the main `picomatch()` function or any of the methods on the picomatch API.
| **Option** | **Type** | **Default value** | **Description** |
| --- | --- | --- | --- |
| `basename` | `boolean` | `false` | If set, then patterns without slashes will be matched against the basename of the path if it contains slashes. For example, `a?b` would match the path `/xyz/123/acb`, but not `/xyz/acb/123`. |
| `bash` | `boolean` | `false` | Follow bash matching rules more strictly - disallows backslashes as escape characters, and treats single stars as globstars (`**`). |
| `capture` | `boolean` | `undefined` | Return regex matches in supporting methods. |
| `contains` | `boolean` | `undefined` | Allows glob to match any part of the given string(s). |
| `cwd` | `string` | `process.cwd()` | Current working directory. Used by `picomatch.split()` |
| `debug` | `boolean` | `undefined` | Debug regular expressions when an error is thrown. |
| `dot` | `boolean` | `false` | Enable dotfile matching. By default, dotfiles are ignored unless a `.` is explicitly defined in the pattern, or `options.dot` is true |
| `expandRange` | `function` | `undefined` | Custom function for expanding ranges in brace patterns, such as `{a..z}`. The function receives the range values as two arguments, and it must return a string to be used in the generated regex. It's recommended that returned strings be wrapped in parentheses. |
| `failglob` | `boolean` | `false` | Throws an error if no matches are found. Based on the bash option of the same name. |
| `fastpaths` | `boolean` | `true` | To speed up processing, full parsing is skipped for a handful common glob patterns. Disable this behavior by setting this option to `false`. |
| `flags` | `string` | `undefined` | Regex flags to use in the generated regex. If defined, the `nocase` option will be overridden. |
| [format](#optionsformat) | `function` | `undefined` | Custom function for formatting the returned string. This is useful for removing leading slashes, converting Windows paths to Posix paths, etc. |
| `ignore` | `array\|string` | `undefined` | One or more glob patterns for excluding strings that should not be matched from the result. |
| `keepQuotes` | `boolean` | `false` | Retain quotes in the generated regex, since quotes may also be used as an alternative to backslashes. |
| `literalBrackets` | `boolean` | `undefined` | When `true`, brackets in the glob pattern will be escaped so that only literal brackets will be matched. |
| `matchBase` | `boolean` | `false` | Alias for `basename` |
| `maxLength` | `boolean` | `65536` | Limit the max length of the input string. An error is thrown if the input string is longer than this value. |
| `nobrace` | `boolean` | `false` | Disable brace matching, so that `{a,b}` and `{1..3}` would be treated as literal characters. |
| `nobracket` | `boolean` | `undefined` | Disable matching with regex brackets. |
| `nocase` | `boolean` | `false` | Make matching case-insensitive. Equivalent to the regex `i` flag. Note that this option is overridden by the `flags` option. |
| `nodupes` | `boolean` | `true` | Deprecated, use `nounique` instead. This option will be removed in a future major release. By default duplicates are removed. Disable uniquification by setting this option to false. |
| `noext` | `boolean` | `false` | Alias for `noextglob` |
| `noextglob` | `boolean` | `false` | Disable support for matching with extglobs (like `+(a\|b)`) |
| `noglobstar` | `boolean` | `false` | Disable support for matching nested directories with globstars (`**`) |
| `nonegate` | `boolean` | `false` | Disable support for negating with leading `!` |
| `noquantifiers` | `boolean` | `false` | Disable support for regex quantifiers (like `a{1,2}`) and treat them as brace patterns to be expanded. |
| [onIgnore](#optionsonIgnore) | `function` | `undefined` | Function to be called on ignored items. |
| [onMatch](#optionsonMatch) | `function` | `undefined` | Function to be called on matched items. |
| [onResult](#optionsonResult) | `function` | `undefined` | Function to be called on all items, regardless of whether or not they are matched or ignored. |
| `posix` | `boolean` | `false` | Support POSIX character classes ("posix brackets"). |
| `posixSlashes` | `boolean` | `undefined` | Convert all slashes in file paths to forward slashes. This does not convert slashes in the glob pattern itself |
| `prepend` | `boolean` | `undefined` | String to prepend to the generated regex used for matching. |
| `regex` | `boolean` | `false` | Use regular expression rules for `+` (instead of matching literal `+`), and for stars that follow closing parentheses or brackets (as in `)*` and `]*`). |
| `strictBrackets` | `boolean` | `undefined` | Throw an error if brackets, braces, or parens are imbalanced. |
| `strictSlashes` | `boolean` | `undefined` | When true, picomatch won't match trailing slashes with single stars. |
| `unescape` | `boolean` | `undefined` | Remove backslashes preceding escaped characters in the glob pattern. By default, backslashes are retained. |
| `unixify` | `boolean` | `undefined` | Alias for `posixSlashes`, for backwards compatibility. |
picomatch has automatic detection for regex positive and negative lookbehinds. If the pattern contains a negative lookbehind, you must be using Node.js >= 8.10 or else picomatch will throw an error.
### Scan Options
In addition to the main [picomatch options](#picomatch-options), the following options may also be used with the [.scan](#scan) method.
| **Option** | **Type** | **Default value** | **Description** |
| --- | --- | --- | --- |
| `tokens` | `boolean` | `false` | When `true`, the returned object will include an array of tokens (objects), representing each path "segment" in the scanned glob pattern |
| `parts` | `boolean` | `false` | When `true`, the returned object will include an array of strings representing each path "segment" in the scanned glob pattern. This is automatically enabled when `options.tokens` is true |
**Example**
```js
const picomatch = require('picomatch');
const result = picomatch.scan('!./foo/*.js', { tokens: true });
console.log(result);
// {
// prefix: '!./',
// input: '!./foo/*.js',
// start: 3,
// base: 'foo',
// glob: '*.js',
// isBrace: false,
// isBracket: false,
// isGlob: true,
// isExtglob: false,
// isGlobstar: false,
// negated: true,
// maxDepth: 2,
// tokens: [
// { value: '!./', depth: 0, isGlob: false, negated: true, isPrefix: true },
// { value: 'foo', depth: 1, isGlob: false },
// { value: '*.js', depth: 1, isGlob: true }
// ],
// slashes: [ 2, 6 ],
// parts: [ 'foo', '*.js' ]
// }
```
<br>
### Options Examples
#### options.expandRange
**Type**: `function`
**Default**: `undefined`
Custom function for expanding ranges in brace patterns. The [fill-range](https://github.com/jonschlinkert/fill-range) library is ideal for this purpose, or you can use custom code to do whatever you need.
**Example**
The following example shows how to create a glob that matches a folder
```js
const fill = require('fill-range');
const regex = pm.makeRe('foo/{01..25}/bar', {
expandRange(a, b) {
return `(${fill(a, b, { toRegex: true })})`;
}
});
console.log(regex);
//=> /^(?:foo\/((?:0[1-9]|1[0-9]|2[0-5]))\/bar)$/
console.log(regex.test('foo/00/bar')) // false
console.log(regex.test('foo/01/bar')) // true
console.log(regex.test('foo/10/bar')) // true
console.log(regex.test('foo/22/bar')) // true
console.log(regex.test('foo/25/bar')) // true
console.log(regex.test('foo/26/bar')) // false
```
#### options.format
**Type**: `function`
**Default**: `undefined`
Custom function for formatting strings before they're matched.
**Example**
```js
// strip leading './' from strings
const format = str => str.replace(/^\.\//, '');
const isMatch = picomatch('foo/*.js', { format });
console.log(isMatch('./foo/bar.js')); //=> true
```
#### options.onMatch
```js
const onMatch = ({ glob, regex, input, output }) => {
console.log({ glob, regex, input, output });
};
const isMatch = picomatch('*', { onMatch });
isMatch('foo');
isMatch('bar');
isMatch('baz');
```
#### options.onIgnore
```js
const onIgnore = ({ glob, regex, input, output }) => {
console.log({ glob, regex, input, output });
};
const isMatch = picomatch('*', { onIgnore, ignore: 'f*' });
isMatch('foo');
isMatch('bar');
isMatch('baz');
```
#### options.onResult
```js
const onResult = ({ glob, regex, input, output }) => {
console.log({ glob, regex, input, output });
};
const isMatch = picomatch('*', { onResult, ignore: 'f*' });
isMatch('foo');
isMatch('bar');
isMatch('baz');
```

## Globbing features
* [Basic globbing](#basic-globbing) (Wildcard matching)
* [Advanced globbing](#advanced-globbing) (extglobs, posix brackets, brace matching)
### Basic globbing
| **Character** | **Description** |
| --- | --- |
| `*` | Matches any character zero or more times, excluding path separators. Does _not match_ path separators or hidden files or directories ("dotfiles"), unless explicitly enabled by setting the `dot` option to `true`. |
| `**` | Matches any character zero or more times, including path separators. Note that `**` will only match path separators (`/`, and `\\` on Windows) when they are the only characters in a path segment. Thus, `foo**/bar` is equivalent to `foo*/bar`, and `foo/a**b/bar` is equivalent to `foo/a*b/bar`, and _more than two_ consecutive stars in a glob path segment are regarded as _a single star_. Thus, `foo/***/bar` is equivalent to `foo/*/bar`. |
| `?` | Matches any character excluding path separators one time. Does _not match_ path separators or leading dots. |
| `[abc]` | Matches any characters inside the brackets. For example, `[abc]` would match the characters `a`, `b` or `c`, and nothing else. |
#### Matching behavior vs. Bash
Picomatch's matching features and expected results in unit tests are based on Bash's unit tests and the Bash 4.3 specification, with the following exceptions:
* Bash will match `foo/bar/baz` with `*`. Picomatch only matches nested directories with `**`.
* Bash greedily matches with negated extglobs. For example, Bash 4.3 says that `!(foo)*` should match `foo` and `foobar`, since the trailing `*` bracktracks to match the preceding pattern. This is very memory-inefficient, and IMHO, also incorrect. Picomatch would return `false` for both `foo` and `foobar`.
<br>
### Advanced globbing
* [extglobs](#extglobs)
* [POSIX brackets](#posix-brackets)
* [Braces](#brace-expansion)
#### Extglobs
| **Pattern** | **Description** |
| --- | --- |
| `@(pattern)` | Match _only one_ consecutive occurrence of `pattern` |
| `*(pattern)` | Match _zero or more_ consecutive occurrences of `pattern` |
| `+(pattern)` | Match _one or more_ consecutive occurrences of `pattern` |
| `?(pattern)` | Match _zero or **one**_ consecutive occurrences of `pattern` |
| `!(pattern)` | Match _anything but_ `pattern` |
**Examples**
```js
const pm = require('picomatch');
// *(pattern) matches ZERO or more of "pattern"
console.log(pm.isMatch('a', 'a*(z)')); // true
console.log(pm.isMatch('az', 'a*(z)')); // true
console.log(pm.isMatch('azzz', 'a*(z)')); // true
// +(pattern) matches ONE or more of "pattern"
console.log(pm.isMatch('a', 'a*(z)')); // true
console.log(pm.isMatch('az', 'a*(z)')); // true
console.log(pm.isMatch('azzz', 'a*(z)')); // true
// supports multiple extglobs
console.log(pm.isMatch('foo.bar', '!(foo).!(bar)')); // false
// supports nested extglobs
console.log(pm.isMatch('foo.bar', '!(!(foo)).!(!(bar))')); // true
```
#### POSIX brackets
POSIX classes are disabled by default. Enable this feature by setting the `posix` option to true.
**Enable POSIX bracket support**
```js
console.log(pm.makeRe('[[:word:]]+', { posix: true }));
//=> /^(?:(?=.)[A-Za-z0-9_]+\/?)$/
```
**Supported POSIX classes**
The following named POSIX bracket expressions are supported:
* `[:alnum:]` - Alphanumeric characters, equ `[a-zA-Z0-9]`
* `[:alpha:]` - Alphabetical characters, equivalent to `[a-zA-Z]`.
* `[:ascii:]` - ASCII characters, equivalent to `[\\x00-\\x7F]`.
* `[:blank:]` - Space and tab characters, equivalent to `[ \\t]`.
* `[:cntrl:]` - Control characters, equivalent to `[\\x00-\\x1F\\x7F]`.
* `[:digit:]` - Numerical digits, equivalent to `[0-9]`.
* `[:graph:]` - Graph characters, equivalent to `[\\x21-\\x7E]`.
* `[:lower:]` - Lowercase letters, equivalent to `[a-z]`.
* `[:print:]` - Print characters, equivalent to `[\\x20-\\x7E ]`.
* `[:punct:]` - Punctuation and symbols, equivalent to `[\\-!"#$%&\'()\\*+,./:;<=>?@[\\]^_`{|}~]`.
* `[:space:]` - Extended space characters, equivalent to `[ \\t\\r\\n\\v\\f]`.
* `[:upper:]` - Uppercase letters, equivalent to `[A-Z]`.
* `[:word:]` - Word characters (letters, numbers and underscores), equivalent to `[A-Za-z0-9_]`.
* `[:xdigit:]` - Hexadecimal digits, equivalent to `[A-Fa-f0-9]`.
See the [Bash Reference Manual](https://www.gnu.org/software/bash/manual/html_node/Pattern-Matching.html) for more information.
### Braces
Picomatch does not do brace expansion. For [brace expansion](https://www.gnu.org/software/bash/manual/html_node/Brace-Expansion.html) and advanced matching with braces, use [micromatch](https://github.com/micromatch/micromatch) instead. Picomatch has very basic support for braces.
### Matching special characters as literals
If you wish to match the following special characters in a filepath, and you want to use these characters in your glob pattern, they must be escaped with backslashes or quotes:
**Special Characters**
Some characters that are used for matching in regular expressions are also regarded as valid file path characters on some platforms.
To match any of the following characters as literals: `$^*+?()[]
Examples:
```js
console.log(pm.makeRe('foo/bar \\(1\\)'));
console.log(pm.makeRe('foo/bar \\(1\\)'));
```

## Philosophies
The goal of this library is to be blazing fast, without compromising on accuracy.
**Accuracy**
The number one of goal of this library is accuracy. However, it's not unusual for different glob implementations to have different rules for matching behavior, even with simple wildcard matching. It gets increasingly more complicated when combinations of different features are combined, like when extglobs are combined with globstars, braces, slashes, and so on: `!(**/{a,b,*/c})`.
Thus, given that there is no canonical glob specification to use as a single source of truth when differences of opinion arise regarding behavior, sometimes we have to implement our best judgement and rely on feedback from users to make improvements.
**Performance**
Although this library performs well in benchmarks, and in most cases it's faster than other popular libraries we benchmarked against, we will always choose accuracy over performance. It's not helpful to anyone if our library is faster at returning the wrong answer.

# readdirp [![Weekly downloads](https://img.shields.io/npm/dw/readdirp.svg)](https://github.com/paulmillr/readdirp)
Recursive version of [fs.readdir](https://nodejs.org/api/fs.html#fs_fs_readdir_path_options_callback). Exposes a **stream API** and a **promise API**.
```sh
npm install readdirp
```
```javascript
const readdirp = require('readdirp');
// Use streams to achieve small RAM & CPU footprint.
// 1) Streams example with for-await.
for await (const entry of readdirp('.')) {
const {path} = entry;
console.log(`${JSON.stringify({path})}`);
}
// 2) Streams example, non for-await.
// Print out all JS files along with their size within the current folder & subfolders.
readdirp('.', {fileFilter: '*.js', alwaysStat: true})
.on('data', (entry) => {
const {path, stats: {size}} = entry;
console.log(`${JSON.stringify({path, size})}`);
})
// Optionally call stream.destroy() in `warn()` in order to abort and cause 'close' to be emitted
.on('warn', error => console.error('non-fatal error', error))
.on('error', error => console.error('fatal error', error))
.on('end', () => console.log('done'));
// 3) Promise example. More RAM and CPU than streams / for-await.
const files = await readdirp.promise('.');
console.log(files.map(file => file.path));
// Other options.
readdirp('test', {
fileFilter: '*.js',
directoryFilter: ['!.git', '!*modules']
// directoryFilter: (di) => di.basename.length === 9
type: 'files_directories',
depth: 1
});
```
For more examples, check out `examples` directory.
## API
`const stream = readdirp(root[, options])` — **Stream API**
- Reads given root recursively and returns a `stream` of [entry infos](#entryinfo)
- Optionally can be used like `for await (const entry of stream)` with node.js 10+ (`asyncIterator`).
- `on('data', (entry) => {})` [entry info](#entryinfo) for every file / dir.
- `on('warn', (error) => {})` non-fatal `Error` that prevents a file / dir from being processed. Example: inaccessible to the user.
- `on('error', (error) => {})` fatal `Error` which also ends the stream. Example: illegal options where passed.
- `on('end')` — we are done. Called when all entries were found and no more will be emitted.
- `on('close')` — stream is destroyed via `stream.destroy()`.
Could be useful if you want to manually abort even on a non fatal error.
At that point the stream is no longer `readable` and no more entries, warning or errors are emitted
- To learn more about streams, consult the very detailed [nodejs streams documentation](https://nodejs.org/api/stream.html)
or the [stream-handbook](https://github.com/substack/stream-handbook)
`const entries = await readdirp.promise(root[, options])` — **Promise API**. Returns a list of [entry infos](#entryinfo).
First argument is awalys `root`, path in which to start reading and recursing into subdirectories.
### options
- `fileFilter: ["*.js"]`: filter to include or exclude files. A `Function`, Glob string or Array of glob strings.
- **Function**: a function that takes an entry info as a parameter and returns true to include or false to exclude the entry
- **Glob string**: a string (e.g., `*.js`) which is matched using [picomatch](https://github.com/micromatch/picomatch), so go there for more
information. Globstars (`**`) are not supported since specifying a recursive pattern for an already recursive function doesn't make sense. Negated globs (as explained in the minimatch documentation) are allowed, e.g., `!*.txt` matches everything but text files.
- **Array of glob strings**: either need to be all inclusive or all exclusive (negated) patterns otherwise an error is thrown.
`['*.json', '*.js']` includes all JavaScript and Json files.
`['!.git', '!node_modules']` includes all directories except the '.git' and 'node_modules'.
- Directories that do not pass a filter will not be recursed into.
- `directoryFilter: ['!.git']`: filter to include/exclude directories found and to recurse into. Directories that do not pass a filter will not be recursed into.
- `depth: 5`: depth at which to stop recursing even if more subdirectories are found
- `type: 'files'`: determines if data events on the stream should be emitted for `'files'` (default), `'directories'`, `'files_directories'`, or `'all'`. Setting to `'all'` will also include entries for other types of file descriptors like character devices, unix sockets and named pipes.
- `alwaysStat: false`: always return `stats` property for every file. Default is `false`, readdirp will return `Dirent` entries. Setting it to `true` can double readdir execution time - use it only when you need file `size`, `mtime` etc. Cannot be enabled on node <10.10.0.
- `lstat: false`: include symlink entries in the stream along with files. When `true`, `fs.lstat` would be used instead of `fs.stat`
### `EntryInfo`
Has the following properties:
- `path: 'assets/javascripts/react.js'`: path to the file/directory (relative to given root)
- `fullPath: '/Users/dev/projects/app/assets/javascripts/react.js'`: full path to the file/directory found
- `basename: 'react.js'`: name of the file/directory
- `dirent: fs.Dirent`: built-in [dir entry object](https://nodejs.org/api/fs.html#fs_class_fs_dirent) - only with `alwaysStat: false`
- `stats: fs.Stats`: built in [stat object](https://nodejs.org/api/fs.html#fs_class_fs_stats) - only with `alwaysStat: true`
## Changelog
- 3.5 (Oct 13, 2020) disallows recursive directory-based symlinks.
Before, it could have entered infinite loop.
- 3.4 (Mar 19, 2020) adds support for directory-based symlinks.
- 3.3 (Dec 6, 2019) stabilizes RAM consumption and enables perf management with `highWaterMark` option. Fixes race conditions related to `for-await` looping.
- 3.2 (Oct 14, 2019) improves performance by 250% and makes streams implementation more idiomatic.
- 3.1 (Jul 7, 2019) brings `bigint` support to `stat` output on Windows. This is backwards-incompatible for some cases. Be careful. It you use it incorrectly, you'll see "TypeError: Cannot mix BigInt and other types, use explicit conversions".
- 3.0 brings huge performance improvements and stream backpressure support.
- Upgrading 2.x to 3.x:
- Signature changed from `readdirp(options)` to `readdirp(root, options)`
- Replaced callback API with promise API.
- Renamed `entryType` option to `type`
- Renamed `entryType: 'both'` to `'files_directories'`
- `EntryInfo`
- Renamed `stat` to `stats`
- Emitted only when `alwaysStat: true`
- `dirent` is emitted instead of `stats` by default with `alwaysStat: false`
- Renamed `name` to `basename`
- Removed `parentDir` and `fullParentDir` properties
- Supported node.js versions:
- 3.x: node 8+
- 2.x: node 0.6+
