angular-nx-demo

🚀 Quick Start

# Clone the repository
git clone <your-fork-url>
cd <your-repository-name>

# Install dependencies
# (Note: You may need --legacy-peer-deps)
npm install

# Serve the Angular demo application (this will simultaneously serve the API backend)
npx nx serve demo

# ...or you can serve the API separately
npx nx serve api

# Build all projects
npx nx run-many -t build

# Run tests
npx nx run-many -t test

# Lint all projects
npx nx run-many -t lint

# Run e2e tests
npx nx e2e demo-e2e

# Run tasks in parallel

npx nx run-many -t lint test build e2e --parallel=3

# Visualize the project graph
npx nx graph

⭐ Featured Nx Capabilities

This repository showcases several powerful Nx features:

1. 🔒 Module Boundaries

Enforces architectural constraints using tags. Each project has specific dependencies it can use:

• scope:shared - Can be used by all projects
• scope:demo - demo-specific libraries
• scope:api - API-specific libraries
• type:feature - Feature libraries
• type:data - Data access libraries
• type:ui - UI component libraries

Try it out:

# See the current project graph and boundaries
npx nx graph

# View a specific project's details
npx nx show project demo --web

2. 🎭 Playwright E2E Testing

End-to-end testing with Playwright is pre-configured:

# Run e2e tests
npx nx e2e demo-e2e

# Run e2e tests in CI mode
npx nx e2e-ci demo-e2e

4. ⚡ Vitest for Unit Testing

Fast unit testing with Vite for Angular libraries:

# Test a specific library
npx nx test data

# Test all projects
npx nx run-many -t test

5. 🔧 Self-Healing CI

The CI pipeline includes nx fix-ci which automatically identifies and suggests fixes for common issues:

# In CI, this command provides automated fixes
npx nx fix-ci

This feature helps maintain a healthy CI pipeline by automatically detecting and suggesting solutions for:

• Missing dependencies
• Incorrect task configurations
• Cache invalidation issues
• Common build failures

🏷️ Understanding Tags

This repository uses tags to enforce module boundaries:

Project	Tags	Can Import From
demo	scope:demo	scope:demo, scope:shared
api	scope:api	scope:api, scope:shared
feature-products	scope:demo, type:feature	scope:demo, scope:shared
data	scope:demo, type:data	scope:shared
models	scope:shared, type:data	Nothing (base library)

📚 Useful Commands

# Project exploration
npx nx graph                                    # Interactive dependency graph
npx nx list                                     # List installed plugins
npx nx show project demo --web                 # View project details

# Development
npx nx serve demo                              # Serve Angular app
npx nx serve api                               # Serve backend API
npx nx build demo                              # Build Angular app
npx nx test data                               # Test a specific library
npx nx lint feature-products                   # Lint a specific library

# Running multiple tasks
npx nx run-many -t build                       # Build all projects
npx nx run-many -t test --parallel=3          # Test in parallel

🎯 Adding New Features

Generate a new Angular application:

npx nx g @nx/angular:app my-app

Generate a new Angular library:

npx nx g @nx/angular:lib my-lib

Generate a new Angular component:

npx nx g @nx/angular:component my-component --project=my-lib

Generate a new API library:

npx nx g @nx/node:lib my-api-lib

You can use npx nx list to see all available plugins and npx nx list <plugin-name> to see all generators for a specific plugin.
