📌 Bonus Modules in Angular 20
These bonus modules are essential for building high-performance, globally accessible, and modern Angular applications. Whether you’re creating a Progressive Web App, preparing for international users, or aiming for better accessibility and SEO, these advanced features will elevate your standalone Angular 20 apps to a professional level.
1. Progressive Web Apps (PWA)
PWA enables your Angular app to work offline, load faster, and behave like a native mobile app.
🔧 How to Setup PWA
ng add @angular/pwaThis will add a manifest.webmanifest and ngsw-config.json to your app. Angular’s service worker will now cache files and enable offline access.
- Update
angular.jsonto enable serviceWorker in production - Build and deploy your app
- Test offline capability using Chrome DevTools → Application tab → Offline
2. Internationalization (i18n)
Angular’s i18n support allows you to provide translations and regional formats for different languages.
🛠 Steps to Add i18n
- Use the
i18nattribute in your HTML templates - Extract messages using:
ng extract-i18n - Translate the generated
messages.xlfor.jsonfile - Build for a specific locale:
ng build --localize
💡 Tip: You can use libraries like ngx-translate for dynamic, runtime translations.
3. Accessibility (a11y)
Accessibility ensures your application is usable by people with disabilities. Angular provides built-in tools and best practices for a11y compliance.
✅ Key A11y Practices
- Use semantic HTML tags like
<button>,<label>, etc. - Add ARIA attributes for screen readers
- Ensure keyboard navigability
- Use Angular Material which has built-in a11y support
🧪 Testing Accessibility
- Use tools like Lighthouse, Axe, and NVDA screen reader
- Check tab order, contrast ratios, and screen reader output
4. Angular Universal (Server Side Rendering – SSR)
Angular Universal enables SSR for better SEO and faster first load performance.
🚀 Setup Angular Universal
ng add @nguniversal/express-engineThis will:
- Add a server-side app module
- Configure an Express.js backend
- Enable HTML rendering on the server
Run SSR server with:
npm run dev:ssrBenefits of SSR
- Improved SEO for search engines
- Faster time-to-first-byte
- Better social media link previews
✅ Conclusion
These bonus modules — PWA, i18n, a11y, and SSR — future-proof your Angular 20 standalone apps, enhance UX, and improve visibility. Adopt them based on your project needs to deliver a top-tier web experience.
