Angular ngx Bootstrap


 

In order to utilize the ngx Bootstrap in the Angular project, we can implement either of the technique to install:

  • Installing using Angular CLI
  • Installing using the Manual way with npm

Angular ngx Bootstrap

We will understand both the installation procedures, along with knowing their implementation through the examples.

Installing using the Manual way through npm: Before we proceed to install the Angular ngx Bootstrap, we must have installed the Angular CLI in the system. Please refer to the Angular CLI Angular Project Setup article for the detailed installation procedure.

Make sure the Angular CLI & Node Package Manager is installed properly. To check the version installed, run the below commands:

  • For NodeJS version:
node --version
  • For the NPM version:
npm -V OR npm --version
  • For Angular CLI version:
ng -V or ng --version

We will follow the below steps to install the Angular ngx Bootstrap.

Step1: Installation syntax: Run the below command to install the  ngx Bootstrap:

npm install ngx-bootstrap --save

Step 2: After successful installation, add the required package to NgModule imports in the app.module.ts file, as given below:

import { AccordionModule } from 'ngx-bootstrap/accordion';
  
 @NgModule({
   ...
   imports: [ AccordionModule.forRoot(), … ]
   ...
 })

Step 3: Add the following <link> tag in index.html file:

<link href=”https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css” rel=”stylesheet”>

Step 4: Add the component in the app.component.html file:

<accordion [isAnimated]="true">
       <accordion-group heading= "Content">
           Text 
       </accordion-group>
</accordion>

Step 5: Run the app using the following command:

ng serve

It will render the application to the http://localhost:4200/ in the browser.

Installing using Angular CLI:

We can directly add the Boostrap to the Angular project using the ng add command that will update the Bootstrap module in the project.

ng add ngx-bootstrap

Project Structure: After successful installation, the project will contain the following modules & components:
