How to integrate Bootstrap with an Angular project?
Install Bootstrap via npm using npm install bootstrap. 2. Add Bootstrap CSS to the styles array in angular.json: "node_modules/bootstrap/dist/css/bootstrap.min.css". 3. Optionally, install @popperjs/core and bootstrap, then include bootstrap.bundle.min.js in the scripts array. 4. Test by adding a Bootstrap-styled button in a component template; if styled correctly, integration is successful.
To integrate Bootstrap with an Angular project, you can follow a few straightforward steps. The most common and effective way is to install Bootstrap via npm and include it in your project's build configuration.
Install Bootstrap via npm
Open your terminal, navigate to your Angular project directory, and run the following command:
npm install bootstrapThis installs Bootstrap and adds it to your package.json dependencies. By default, this includes Bootstrap CSS (and optionally JavaScript if needed).
Include Bootstrap CSS in angular.json
After installation, you need to tell Angular to include Bootstrap’s CSS in the build process. Open angular.json and locate the styles array under the build options:
- Add "node_modules/bootstrap/dist/css/bootstrap.min.css" to the styles array.
Your styles section should look like this:
"styles": ["src/styles.css",
"node_modules/bootstrap/dist/css/bootstrap.min.css"
]
Optional: Add Bootstrap JavaScript (via Popper)
If you need Bootstrap components like modals, dropdowns, or tooltips that rely on JavaScript, you can include Bootstrap’s JS bundle. First, install Popper and Bootstrap (if not already installed):
npm install @popperjs/core bootstrapThen add the Bootstrap JavaScript file in the scripts array in angular.json:
"scripts": ["node_modules/bootstrap/dist/js/bootstrap.bundle.min.js"
]
This gives access to Bootstrap’s interactive components through vanilla JavaScript or custom directives.
Verify Integration
Create a simple test in one of your component templates (e.g., app.component.html):
If the button appears styled with Bootstrap’s primary color, the integration was successful.
Basically just install, configure, and test. That’s how you get Bootstrap working smoothly in an Angular app.

By the end of this tutorial, you will see a fully working demo written in Angular and Node.js.
