Why should you care?

SPAs live or die on routing and solid forms.

See it live — copy this example

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

// Form Validation
export const routes: Routes = [
  { path: 'items/:id', component: ItemComponent },
];

What happened?

• Declare routes or form controls explicitly in TypeScript.
• 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 Form Validation simply. You ran a small Angular demo. You know one pitfall.

Your team applies form validation on an admin UI.
