Integrating Bootstrap with Angular makes UI development faster and more efficient. In this guide, you will find a detailed, step-by-step tutorial on how to install Bootstrap in Angular 19

npm install -g @angular/cli //install angular CLI
ng new my-angular-bootstrap-app //create new angular projectNavigate to the project directory:
cd my-angular-bootstrap-appRun the application with:
ng serveYour Angular app will now be available at http://localhost:4200/.
Step 2: Install Bootstrap in Angular 19

Method 1: Install via npm (Recommended Approach)
Run the following command to install Bootstrap:
npm install bootstrapTo install Bootstrap icons separately, use:

Method 2: Use Bootstrap CDN (Alternative Approach)
For a quick setup, copy the latest Bootstrap CDN links from Bootstrap’s official site and add them to the <head> section of src/index.html:
<!-- Bootstrap CSS -->
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap@5.3.2/dist/css/bootstrap.min.css">
<!-- Bootstrap JS -->
<script src="https://cdn.jsdelivr.net/npm/bootstrap@5.3.2/dist/js/bootstrap.bundle.min.js"></script>While this method is helpful for prototyping, it does not support deep customization.

]Option 2: Import Bootstrap in styles.css (or styles.scss)

@import 'bootstrap/dist/css/bootstrap.min.css';For styles.scss:
@import 'bootstrap/scss/bootstrap';Step 4: Verify Bootstrap Installation

<button class="btn btn-primary">Click Me</button>Now, run:
ng serveIf the button appears styled on http://localhost:4200/, Bootstrap is successfully integrated into Angular with Bootstrap.
