What is this?

Dev Server and Build Scripts gets your Angular toolchain and project ready.

Why should you care?

Without a clean setup, every later lesson fights the environment.

See it live — copy this example

Run examples in an Angular CLI project (ng serve). Prefer standalone components and TypeScript strict mode.

# Dev Server and Build Scripts
ng version
ng new angularverse --defaults
cd angularverse && ng serve

What happened?

  • CLI version, new app, and serve are the bootstrap path for your Angular app.
  • Follow the steps below — typing the code yourself is the fastest way to learn.

Practice next

  1. Reproduce the snippet in an Angular CLI app.
  2. Change one binding or route and re-serve.
  3. Note one mistake you almost made.
  4. Extract a service.
  5. Add a trivial unit test later.

Remember

You can explain Dev Server and Build Scripts simply. You ran a small Angular demo. You know one pitfall.

Dev Server and Build Scripts in AngularVerse

Your team applies dev server and build scripts on an admin UI.

Outcome: A concrete next coding step exists.

How do you optimize Angular applications for faster load times? ● Use Ahead-of-Time (AOT) compilation for faster rendering. ● Enable production builds (ng build --prod) with optimizations: ○ Minification ○ Tree shaking ○ Dead code elimination ● Use lazy loading for feature modules. ● Bundle analysis: Use tools like source-map-explorer to find large bundles. ● Use Angular’s built-in caching and service workers (via Angular PWA) for offline
nd faster repeat loads. Optimize images and assets (compress, lazy load). Use OnPush change detection for components to reduce unnecessary UI updates. Avoid memory leaks by unsubscribing from observables. Use trackBy fun…
