This is my practice file created along the way of learning Bootstrap 4, excited to explore more.
Installing Bootstrap in Angular6 (taken from https://stackoverflow.com/questions/43557321/angular-4-how-to-include-bootstrap) npm install bootstrap --save npm install jquery --save npm install popper.js --save
And edit angular.json as below (../ had to be removed to point libraries to correct path)
"styles": [
"node_modules/bootstrap/dist/css/bootstrap.min.css",
"styles.css"
],
"scripts": [
"node_modules/jquery/dist/jquery.min.js",
"node_modules/popper.js/dist/umd/popper.min.js",
"node_modules/bootstrap/dist/js/bootstrap.min.js"
],
