How to add Bootstrap 5 to your Angular 11 project

#angular #bootstrap5 #popperjs #programming

First things first you want to add bootstrap 5 as an npm package like so

npm install bootstrap@next

In your angular.json add bootstrap stylesheet and javascript

"styles": [
  "src/scss/styles.scss",
  "./node_modules/bootstrap/dist/css/bootstrap.min.css",
],

"scripts": [
  "./node_modules/bootstrap/dist/js/bootstrap.min.js"
]

Now add popperjs and add it to your scripts

npm install @popperjs/core

"scripts": [
  "./node_modules/@popperjs/core/dist/umd/popper.min.js",
  "./node_modules/bootstrap/dist/js/bootstrap.min.js"
]

Now lets test and see if everything works accordingly

  >
