+# UiDataUtils
+
+This project was generated using [Angular CLI](https://github.com/angular/angular-cli) version 19.2.0.
+
+## Code scaffolding
+
+Angular CLI includes powerful code scaffolding tools. To generate a new component, run:
+
+```bash
+ng generate component component-name
+```
+
+For a complete list of available schematics (such as `components`, `directives`, or `pipes`), run:
+
+```bash
+ng generate --help
+```
+
+## Building
+
+To build the library, run:
+
+```bash
+ng build ui-data-utils
+```
+
+This command will compile your project, and the build artifacts will be placed in the `dist/` directory.
+
+### Publishing the Library
+
+Once the project is built, you can publish your library by following these steps:
+
+1. Navigate to the `dist` directory:
+   ```bash
+   cd dist/ui-data-utils
+   ```
+
+2. Run the `npm publish` command to publish your library to the npm registry:
+   ```bash
+   npm publish
+   ```
+
+## Running unit tests
+
+To execute unit tests with the [Karma](https://karma-runner.github.io) test runner, use the following command:
+
+```bash
+ng test
+```
+
+## Running end-to-end tests
+
+For end-to-end (e2e) testing, run:
+
+```bash
+ng e2e
+```
+
+Angular CLI does not come with an end-to-end testing framework by default. You can choose one that suits your needs.
