Angular CLI Generate Guard

If you want to protect your routes, you can use Angular Guards. Angular Guards are classes that implement the CanActivate interface, which decides whether a route can be activated or not. You can generate a Guard using the Angular CLI.

Steps to generate a Guard using the Angular CLI

  1. Open your terminal or command prompt.
  2. Navigate to your project folder.
  3. Run the following command:
ng generate guard guard-name

This command will generate a new file named guard-name.guard.ts in the src/app/ directory.

Different ways to generate a Guard using the Angular CLI

You can also use the following commands to generate different types of Guards:

  • CanActivate
ng generate guard guard-name --implements CanActivate
  • CanActivateChild
ng generate guard guard-name --implements CanActivateChild
  • CanDeactivate
ng generate guard guard-name --implements CanDeactivate
  • Resolve
ng generate guard guard-name --implements Resolve
  • CanLoad
ng generate guard guard-name --implements CanLoad

These commands will generate different types of Guards with the corresponding implements interface implemented.

Once you've generated a Guard, you can use it to protect your routes by adding it to the canActivate or canActivateChild properties in your routes configuration.

const routes: Routes = [
    path: 'protected',
    component: ProtectedComponent,
    canActivate: [AuthGuard]

In this example, the AuthGuard is used to protect the /protected route.

That's it! Now you know how to generate a Guard using the Angular CLI and how to use it to protect your routes.
