## ๐ฆ Project Overview
This repository demonstrates a production-ready Angular monorepo with:
- **2 Applications**
- `shop` - Angular e-commerce application with product listings and detail views
- `api` - Backend API with Docker support serving product data
- **6 Libraries**
- `@org/feature-products` - Product listing feature (Angular)
- `@org/feature-product-detail` - Product detail feature (Angular)
- `@org/data` - Data access layer for shop features
- `@org/shared-ui` - Shared UI components
- `@org/models` - Shared data models
- `@org/products` - API product service library
- **E2E Testing**
- `shop-e2e` - Playwright tests for the shop application
## ๐ Quick Start
```bash
# 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 shop application (this will simultaneously serve the API backend)
npx nx run shop:serve
# ...or you can serve the API separately
npx nx run api:serve
# 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 run shop-e2e:e2e
# Run tasks in parallel
npx nx run-many -t lint test build e2e --parallel=3
# Visualize the project graph
npx nx graph
```
## โญ Featured Nx Capabilities
This repository showcases several powerful Nx features:
### 1. ๐ Module Boundaries
Enforces architectural constraints using tags. Each project has specific dependencies it can use:
- `scope:shared` - Can be used by all projects
- `scope:shop` - Shop-specific libraries
- `scope:api` - API-specific libraries
- `type:feature` - Feature libraries
- `type:data` - Data access libraries
- `type:ui` - UI component libraries
**Try it out:**
```bash
# See the current project graph and boundaries
npx nx graph
# View a specific project's details
npx nx show project shop --web
```
[Learn more about module boundaries โ](https://nx.dev/docs/features/enforce-module-boundaries)
### 2. ๐ณ Docker Integration
The API project includes Docker support with automated targets and release management:
```bash
# Build Docker image
npx nx run api:docker:build
# Run Docker container
npx nx run api:docker:run
# Release with automatic Docker image versioning
npx nx release
```
**Nx Release for Docker:** The repository is configured to use Nx Release for managing Docker image versioning and publishing. When running `nx release`, Docker images for the API project are automatically versioned and published based on the release configuration in `nx.json`. This integrates seamlessly with semantic versioning and changelog generation.

### 3. ๐ญ Playwright E2E Testing
End-to-end testing with Playwright is pre-configured:
```bash
# Run e2e tests
npx nx run shop-e2e:e2e
# Run e2e tests in CI mode
npx nx run shop-e2e:e2e-ci
```
[Learn more about E2E testing โ](https://nx.dev/docs/technologies/test-tools/playwright)
### 4. โก Vitest for Unit Testing
Fast unit testing with Vite for Angular libraries:
```bash
# Test a specific library
npx nx run data:test
# Test all projects
npx nx run-many -t test
```
[Learn more about Vite testing โ](https://nx.dev/docs/technologies/build-tools/vite)
### 5. ๐ง Self-Healing CI
The CI pipeline includes `nx fix-ci` which automatically identifies and suggests fixes for common issues:
```bash
# 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

## ๐ท๏ธ Understanding Tags
This repository uses tags to enforce module boundaries:
| Project | Tags | Can Import From |
| ------------------ | ---------------------------- | ---------------------------- |
| `shop` | `scope:shop` | `scope:shop`, `scope:shared` |
| `api` | `scope:api` | `scope:api`, `scope:shared` |
| `feature-products` | `scope:shop`, `type:feature` | `scope:shop`, `scope:shared` |
| `data` | `scope:shop`, `type:data` | `scope:shared` |
| `models` | `scope:shared`, `type:data` | Nothing (base library) |
