The Nx Plugin for Angular contains executors, generators, and utilities for managing Angular applications and libraries within an Nx workspace. It provides: 

- Integration with libraries such as Storybook, Jest, ESLint, Tailwind CSS, Cypress, Karma, and Protractor. 

- Generators to help scaffold code quickly (like: Micro Frontends, Libraries, both internal to your codebase and publishable to npm) 

- Upgrading AngularJS applications 

- Single Component Application Modules (SCAMs) 

- NgRx helpers. 

- Utilities for automatic workspace refactoring.

The Nx Plugin for Angular contains executors, generators, and utilities for managing Angular applications and libraries within an Nx workspace. It provides:

- Integration with libraries such as Storybook, Jest, Cypress, Karma, and Protractor.
- Generators to help scaffold code quickly, including:
  - Micro Frontends
  - Libraries, both internal to your codebase and publishable to npm
  - Upgrading AngularJS applications
  - Single Component Application Modules (SCAMs)
- NgRx helpers.
- Utilities for automatic workspace refactoring.

## Setting up the Angular plugin

Adding the Angular plugin to an existing Nx workspace can be done with the following:

```bash
yarn add -D @nrwl/angular
```

```bash
npm install -D @nrwl/angular
```

## Using the Angular Plugin

### Generating an application

It's straightforward to generate an Angular application:

```bash
nx g @nrwl/angular:app appName
```

By default, the application will be generated with:

- ESLint as the linter.
- Jest as the unit test runner.
- Cypress as the E2E test runner.

We can then serve, build, test, lint, and run e2e tests on the application with the following commands:

```bash
nx serve appName
nx build appName
nx test appName
nx lint appName
nx e2e appName
```

### Generating a library

Generating an Angular library is very similar to generating an application:

```bash
nx g @nrwl/angular:lib libName
```

By default, the library will be generated with:

- ESLint as the linter.
- Jest as the unit test runner.

We can then test and lint the library with the following commands:

```bash
nx test libName
nx lint libName
```

Converts a project from TSLint to ESLint.

convert-tslint-to-eslint

Convert an Angular project from TSLint to ESLint. NOTE: Does not work in `--dry-run mode`.

The following will first configure the project, `myapp`, the same way a _new_ project is configured i.e. It will use Nx's new recommended ESLint config. By default, this also adds the existing TSLint configuration on top of the default ESLint config from Nx to continue checking what it checks today. This is done by migrating TSLint rules to their equivalent ESLint rules to the best of its abilities. Some TSLint rules may not have ESLint equivalents and will be reported during the conversion

If your TSLint config isn't extremely important to you, ignoring it makes this process more deterministic. Unlike the prior example, this will discard the existing TSLint configuration, meaning that the project will only have the Nx's latest recommended ESLint configuration which may be good enough for some workspaces

By default, this process removes the TSLint related dependencies and configuration once no more projects use TSLint. This can be disabled with the following flag to keep TSLint related dependencies and configuration in the repo

If true, it will not use existing TSLint config as a reference, it will just reset the project with the latest recommended ESLint config.

The name of the Angular project to convert. Please note, if the project is an Angular app with an associated Cypress e2e project, it will also attempt to convert that.

If this conversion leaves no more TSLint usage in the workspace, it will remove TSLint and related dependencies and configuration.
