In this post, I'll walk you through the steps I followed to add ng-bootstrap to an Angular 4 project created using the Angular CLI.


  • Node.js (and npm)
  • TypeScript
  • Angular CLI

To install Node.js (and npm):

curl -sL | sudo -E bash 
sudo apt-get install -y nodejs

To install TypeScript:

sudo npm install -g typescript

To install the Angular CLI:

sudo npm install -g @angular/cli

ng new

The Angular CLI makes it easy to create scaffolding for new applications, open a terminal session and run the following command:

ng new angular-ng-bootstrap

You should see output like:

installing ng
  create .editorconfig
  create src/app/app.component.css
  create src/app/app.component.html
  create src/app/app.component.spec.ts
  create src/app/app.component.ts
  create src/app/app.module.ts
  create src/assets/.gitkeep
  create src/environments/
  create src/environments/environment.ts
  create src/favicon.ico
  create src/index.html
  create src/main.ts
  create src/polyfills.ts
  create src/styles.css
  create src/test.ts
  create src/
  create src/tsconfig.spec.json
  create src/typings.d.ts
  create .angular-cli.json
  create e2e/app.e2e-spec.ts
  create e2e/app.po.ts
  create e2e/tsconfig.e2e.json
  create .gitignore
  create karma.conf.js
  create package.json
  create protractor.conf.js
  create tsconfig.json
  create tslint.json
Successfully initialized git.
Installing packages for tooling via yarn.
Installed packages for tooling via yarn.
Project 'angular-ng-bootstrap' successfully created.

Now, we can navigate to the angular-ng-bootstrap directory:

cd angular-ng-bootstrap

And, use the Angular CLI's built in HTTP server to run our new application:

ng serve

You should see output like:

** NG Live Development Server is listening on localhost:4200, open your browser on http://localhost:4200 **

ng-bootstrap contains a set of native Angular components based on Bootstrap 4's markup and CSS.

Get Bootstrap 4

Head over to Bootstrap 4's download page and grap a copy of the ready-to-use compiled code:



Update styles.css to import Bootstrap's CSS:

/* Bootstrap 4 CSS */
@import './app/vendor/bootstrap/4.0.0-beta/css/bootstrap.min.css';

Now, we're ready to install ng-bootstrap:

npm install --save @ng-bootstrap/ng-bootstrap


Update app.module.ts to import ng-bootstrap and add it to the list of imports:

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { AppComponent } from './app.component';
import { NgbModule } from '@ng-bootstrap/ng-bootstrap';

  declarations: [
  imports: [
  providers: [],
  bootstrap: [AppComponent]
export class AppModule { }

ng-bootstrap demo

Now, we can use some sample code from the ng-bootstrap demo to check that everything is working as expected:
