Explanation

Angular Bootstrap is built on top of Bootstrap, which provides a set of CSS and JavaScript files that add functionality and styling to HTML elements. Installing Angular Bootstrap via npm provides you with the framework and its dependencies, allowing you to use its components in your Angular project.

Use

To use Angular Bootstrap, you need to import the module in your Angular component:

import { ModalModule } from 'ngx-bootstrap/modal';

@NgModule({
  imports: [ ModalModule.forRoot() ],
  ...
})

After importing the module, you can use its components in your HTML templates:

<button class="btn btn-primary" (click)="showModal()">Login</button>

<ng-template #modalTemplate>
  <div class="modal-header">
    <h4 class="modal-title pull-left">Login</h4>
  </div>
  <div class="modal-body">
    <form>
      <div class="form-group">
        <label>Email</label>
        <input type="email" class="form-control" [(ngModel)]="email">
      </div>
      <div class="form-group">
        <label>Password</label>
        <input type="password" class="form-control" [(ngModel)]="password">
      </div>
    </form>
  </div>
  <div class="modal-footer">
    <button class="btn btn-primary" (click)="login()">Login</button>
    <button class="btn btn-default" (click)="cancel()">Cancel</button>
  </div>
</ng-template>
