Best Practices

• Use generators for scaffolding

# Generate component
ng g c components/my-component

# Generate service
ng g s services/my-service

# Generate guard
ng g g guards/auth

# Generate interceptor
ng g interceptor timing

# Generate library
ng g library my-lib

# Generate with standalone
ng g c my-component --standalone

• Use schematics for migrations

# Migrate to control flow
ng g @angular/core:control-flow

# Migrate to signal inputs
ng g @angular/core:signal-input-migration

# Migrate to lazy loading routes
ng g @angular/core:route-lazy-loading

• Use ng add for packages

# Add Angular Material
ng add @angular/material

# Add SSR
ng add @angular/ssr

# Add PWA
ng add @angular/pwa

• Configure workspace defaults

{
  "$schema": "./node_modules/@angular/cli/lib/config/schema.json",
  "version": 1,
  "newProjectRoot": "projects",
  "projects": {
    "my-app": {
      "schematics": {
        "@schematics/angular:component": {
          "style": "scss",
          "standalone": true
        }
      }
    }
  }
}

• Use ng run for builders

# Run custom builder
ng run my-app:build

# Run SSR
ng run my-app:serve-ssr

# Run prerender
ng run my-app:prerender

• Use ng config for settings

# Set default style
ng config defaults.style=scss

# Enable analytics
ng analytics enable

• Use ng update for migrations

# Update packages
ng update

# Update specific package
ng update @angular/core

• Use ng build with options

# Production build
ng build --configuration=production

# Dev build with stats
ng build --stats-json

• Use standalone by default

# New project with standalone
ng new my-app --standalone

• Use functional over class-based

# Generate functional guard
ng g g guards/auth --functional

# Generate functional interceptor
ng g interceptor my-interceptor --functional
