What is this?

Module Federation Idea covers realtime UX or splitting large frontends.

Why should you care?

Ops dashboards and multi-team apps need these patterns.

See it live — copy this example

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

// Push updates -> subjects/signals -> template

What happened?

  • Define the event source and the UI state it updates.
  • 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 Module Federation Idea simply. You ran a small Angular demo. You know one pitfall.

How do you test Angular components? ● Use Angular’s TestBed to create a testing module that declares the component. ● Instantiate the component and its template for testing. ● Test component logic, DOM rendering, event handling, and bindings. ● Use Angular testing utilities like fixture.detectChanges() to update the view. Basic example: beforeEach(async () => {
wait TestBed.configureTestingModule({ declarations: [MyComponent] }).compileComponents(); fixture = TestBed.createComponent(MyComponent); component = fixture.componentInstance; fixture.detectChanges(); }); it('should cre…

How do you structure Angular projects for scalability? ● Feature-based folder structure: Organize by features rather than by type. /src/app /products /components /services /models products.module.ts /orders /shared /core ● Core module: For singleton services used app-wide (e.g., authentication, logging). ● Shared module: For shared components, pipes, and directives reused across the
Answer: pp. Lazy load feature modules: Load modules on demand to improve startup time. Use state management (e.g., NgRx) when app state becomes complex. Adopt consistent routing with child routes. What interviewers expec…

What is the role of NgModule in Angular?
@NgModule is a decorator that defines a module. It declares which components, directives, and pipes belong to the module. It imports other modules needed for its components. It exports components/modules to make them ava…
