angular-tooling

name	angular-tooling
description	Use Angular CLI and development tools effectively in Angular v20+ projects. Use for project setup, code generation, building, testing, and configuration. Triggers on creating new projects, generating components/services/modules, configuring builds, running tests, or optimizing production builds. Don't use for Nx workspace commands, custom Webpack configurations, or non-Angular CLI build systems like Vite standalone or esbuild direct usage.

Angular Tooling

Use Angular CLI and development tools for efficient Angular v20+ development.

Project Setup

Create New Project

# Create new standalone project (default in v20+)
ng new my-app

# With specific options
ng new my-app --style=scss --routing --ssr=false

# Skip tests
ng new my-app --skip-tests

# Minimal setup
ng new my-app --minimal --inline-style --inline-template

Code Generation

Components

# Generate component
ng generate component features/user-profile
ng g c features/user-profile  # Short form

# With options
ng g c shared/button --inline-template --inline-style
ng g c features/dashboard --skip-tests
ng g c features/settings --change-detection=OnPush

# Flat (no folder)
ng g c shared/icon --flat

# Dry run (preview)
ng g c features/checkout --dry-run

Services

# Generate service (providedIn: 'root' by default)
ng g service services/auth
ng g s services/user

# Skip tests
ng g s services/api --skip-tests

Other Schematics

# Directive
ng g directive directives/highlight
ng g d directives/tooltip

# Pipe
ng g pipe pipes/truncate
ng g p pipes/date-format

# Guard (functional by default)
ng g guard guards/auth

# Interceptor (functional by default)
ng g interceptor interceptors/auth

# Interface
ng g interface models/user

# Enum
ng g enum models/status

# Class
ng g class models/product

Generate with Path Alias

# Components in feature folders
ng g c @features/products/product-list
ng g c @shared/ui/button

Development Server

# Start dev server
ng serve
ng s  # Short form

# With options
ng serve --port 4201
ng serve --open  # Open browser
ng serve --host 0.0.0.0  # Expose to network

# Production mode locally
ng serve --configuration=production

# With SSL
ng serve --ssl --ssl-key ./ssl/key.pem --ssl-cert ./ssl/cert.pem

Building

Development Build

ng build

Production Build

ng build --configuration=production
ng build -c production  # Short form

# With specific options
ng build -c production --source-map=false
ng build -c production --named-chunks

Build Output

│   ├── main-[hash].js
│   ├── polyfills-[hash].js
│   └── styles-[hash].css
└── server/              # If SSR enabled
    └── main.js

Testing

Unit Tests

# Run tests
ng test
ng t  # Short form

# Single run (CI)
ng test --watch=false --browsers=ChromeHeadless

# With coverage
ng test --code-coverage

# Specific file
ng test --include=**/user.service.spec.ts

E2E Tests

# Run e2e (if configured)
ng e2e

Linting

# Run linter
ng lint

# Fix auto-fixable issues
ng lint --fix

Environment Configuration

// src/environments/environment.ts
export const environment = {
  production: false,

};

Configure in angular.json:

{
  "configurations": {
    "production": {
      "fileReplacements": [
