Part 15: Angular Deployment – Professional Deployment Strategies

Welcome to the final installment of our Angular series! Let’s explore how to deploy your Angular application like a pro, covering everything from basic hosting to advanced CI/CD pipelines.

1. Preparing for Production

Production Build

bash

ng build --prod
# Or in newer versions:
ng build --configuration=production

What this includes:

• Ahead-of-Time (AOT) compilation
• Tree shaking and dead code elimination
• Minification and uglification
• Source map generation (optional)
• Budget warnings (configured in angular.json)

Environment Configurations

typescript

// environment.prod.ts
export const environment = {
  production: true,
  apiUrl: 'https://api.yourdomain.com',
  analyticsId: 'UA-XXXXX-Y'
};

2. Hosting Options

Static Hosting (Best for SPAs)

Provider	Command/Notes	Free Tier
Firebase Hosting	firebase init hosting + firebase deploy	1GB storage
Netlify	Drag-and-drop dist folder	100GB bandwidth
GitHub Pages	ng deploy --base-href=/repo-name/	Unlimited sites
AWS S3 + CloudFront	Manual S3 upload + CDN config	Pay-as-you-go
Vercel	Automatic Git integration	100GB bandwidth

Server-Side Rendering (SSR) Options

bash

# Add Angular Universal
ng add @nguniversal/express-engine

Hosting for SSR:

• Node.js servers (Express)
• Serverless functions (Firebase, AWS Lambda)
• Cloud providers (Azure App Service, Google App Engine)

3. Deployment Automation

Basic CI/CD Pipeline (GitHub Actions)

yaml

# .github/workflows/deploy.yml
name: Deploy to Firebase

on:
  push:
    branches: [ main ]

jobs:
  build-and-deploy:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - run: npm ci
      - run: npm run build -- --configuration=production
      - run: npm run deploy

Advanced CI/CD Features

1. Automated TestingyamlCopyDownload- run: npm test — –watch=false –browsers=ChromeHeadless – run: npm run e2e
2. Preview Deployments for PRsyamlCopyDownloadon: pull_request: branches: [ main ]
3. Multi-Environment DeploymentyamlCopyDownloadstrategy: matrix: environment: [staging, production]

4. Performance Optimization for Production

Lazy Loading Configuration

typescript

// In routing modules
{
  path: 'admin',
  loadChildren: () => import('./admin/admin.module')
                     .then(m => m.AdminModule)
}

Preloading Strategy

typescript

RouterModule.forRoot(routes, {
  preloadingStrategy: QuicklinkStrategy
})

Differential Loading

Enabled by default in Angular CLI:

• Modern browsers: ES2015+
• Legacy browsers: ES5

5. Monitoring and Analytics

Error Tracking

typescript

// Error handler service
export class ErrorHandler implements ErrorHandler {
  handleError(error: any) {
    // Send to error tracking service
    console.error(error);
  }
}

Performance Monitoring

typescript

// Track route changes
this.router.events.pipe(
  filter(event => event instanceof NavigationEnd)
).subscribe(() => {
  // Send to analytics
});

6. Security Best Practices

1. Content Security Policy (CSP)htmlCopyDownloadRun<meta http-equiv=”Content-Security-Policy” content=”default-src ‘self’; script-src ‘self’ ‘unsafe-inline'”>
2. HTTPS Enforcement
   • Configure at hosting provider
   • Use services like Let’s Encrypt
3. Security HeaderstextCopyDownloadX-Content-Type-Options: nosniff X-Frame-Options: DENY Strict-Transport-Security: max-age=31536000

7. Advanced Deployment Scenarios

Multi-Region Deployment

yaml

# Cloudflare Workers configuration
addEventListener('fetch', event => {
  event.respondWith(handleRequest(event))
})

async function handleRequest(event) {
  // Route to nearest CDN edge
}

Blue-Green Deployment

1. Deploy new version alongside old
2. Route traffic gradually
3. Monitor for errors
4. Complete cutover

8. Post-Deployment Checklist

1. Verify all routes (no 404s)
2. Test forms and API calls
3. Check console for errors
4. Validate performance metrics
5. Confirm analytics tracking
6. Test on multiple devices

Hands-On Deployment Exercise

1. Create a free Firebase account
2. Initialize Firebase Hosting
3. Configure production environment
4. Set up GitHub Actions deployment
5. Deploy and verify your app
