ng-bootstrap is a set of components and directives that wrap the latest version of Bootstrap (v4.0.0 alpha 6 at the time of this writing). This makes it easy to use Bootstrap in your Angular apps.

Angular 4+ is required to use ng-bootstrap.

ng-bootstrap depends on Bootstrap’s CSS being available, but you don’t need the Bootstrap JS or jQuery dependencies.

Let’s install everything we need into our project and even add Font Awesome to the mix:

$ npm install --save @ng-bootstrap/ng-bootstrap [email protected] font-awesome

Or if you prefer using Yarn:

$ yarn add @ng-bootstrap/ng-bootstrap [email protected] font-awesome

Assuming that your Angular app is an Angular CLI project, just add the following in the styles array of the .angular-cli.json file:

"../node_modules/bootstrap/dist/css/bootstrap.min.css", "../node_modules/font-awesome/css/font-awesome.min.css"

This will take care of adding the CSS dependencies for Bootstrap and Font Awesome. Note that you may need to restart your dev server at this point.

Here’s an example that shows off some of the custom components and directives available with ng-bootstrap:

<div class="jumbotron"> <div class="container"> <ngb-alert type="success" [dismissible]="false"> Bootstrap is working! </ngb-alert> <h1> <i class="fa fa-bath" aria-hidden="true"></i> And so is Font Awesome! </h1> </div> </div> <div class="container"> <p> A progress bar: <ngb-progressbar showValue="true" type="success" [value]="65"> </ngb-progressbar> </p> </div> <div class="container"> <ngb-tabset> <ngb-tab title="Bacon"> <ng-template ngbTabContent> <p class="mt-4">Content for tab 1. <button type="button" class="btn btn-secondary" placement="bottom" ngbPopover="A popover in tab 1" popoverTitle="Bacon is good"> Click me </button> </p> </ng-template> </ngb-tab> <ngb-tab title="Lettuce"> <ng-template ngbTabContent> <p>Content for tab 2</p> </ng-template> </ngb-tab> <ngb-tab title="Tomatoes"> <ng-template ngbTabContent> <p>Content for tab 3</p> </ng-template> </ngb-tab> </ngb-tabset> </div> 

Notice the use of the ngb-alert, ngb-progressbar and ngb-tabset components.

Refer to the official ng-bootstrap documentation for the syntax on the available components.
