Usage

Add SidebarModule to your app module:

import { SidebarModule } from 'ng-sidebar';

@NgModule({
  declarations: [AppComponent],
  imports: [BrowserModule, SidebarModule],
  bootstrap: [AppComponent],
})
class AppModule {}

If you're using it in a feature module, you may need to add it as an import in that module as well.

In your app component, simply use add a <ng-sidebar-container> wrapper, then place your <ng-sidebar>(s) and content within it:

@Component({
  selector: 'app',
  template: `
    <!-- Container for sidebar(s) + page content -->
    <ng-sidebar-container>

      <!-- A sidebar -->
      <ng-sidebar [(opened)]="_opened">
        <p>Sidebar contents</p>
      </ng-sidebar>

      <!-- Page content -->
      <button (click)="_toggleSidebar()">Toggle sidebar</button>

    </ng-sidebar-container>
  `
})
class AppComponent {
  private _opened: boolean = false;

  private _toggleSidebar() {
    this._opened = !this._opened;
  }
}

A directive is also provided to easily close the sidebar by clicking something inside it:

<ng-sidebar>
  <a closeSidebar>Closes the sidebar</a>
</ng-sidebar>

You can also use the open() and close() functions:

<ng-sidebar #sidebar>
  <button (click)="sidebar.close()">Close sidebar</button>
</ng-sidebar>

<button (click)="sidebar.open()">Open sidebar</button>
