I’ve had some problems getting the bootstrap 4 beta scss npm package to work with Angular 4 (angular/cli actuall) and found the solution to the issue today. I missed a detail in the bootstrap documentation to use the jquery-slim verion and had been using jquery-min instead. The webpack error thrown wasn’t particularly helpful and gave me back something about undefined value. Well, forget all that and if you get an error, hop over and check to make sure you’re importing the jquery.slim.js file before banging your head against a wall.
So to have a complete set of instructions for using Bootstrap 4 Beta in an Angular 4 project.
Install dependencies via npm:
npm install --save firstname.lastname@example.org jquery@latest popper.js@latest
Note that in this version tether is no longer required, you can uninstall it if upgrading.
styles.scss import bootstrap and a local _variables.scss file (wherever you put it):
@import '../node_modules/bootstrap/scss/bootstrap'; @import 'sass/variables';
... "scripts": [ "../node_modules/jquery/dist/jquery.slim.js", "../node_modules/popper.js/dist/umd/popper.js", "../node_modules/bootstrap/dist/js/bootstrap.js" ] ...
Again, not the jquery.slim.js import
That’s it, it should now work.
