bootstrap image carousel does not work in angular
The first image of the carousel appears in my page, however the buttons do not work and neither does the images move. I have tried using different types of bootstrap carousel but to no avail. I saw some answers which suggested to add jQuery and Bootstrap links to the top, so i tried that but didn’t work either. I think the issue could be due to the fact that i am working on angular? I also noticed that when i clicked on the buttons, my localhost link would change from localhost:3000 to localhost:3000/#carouselExampleIndicators

Bootstrap requires JQuery for this kind of actions. You either need to add jquery in your index.html or add it to angular-cli.json or angular.json (depending on your version of Angular):
Approach 1 (Recommended):
Run first this command to install both JQuery and Bootstrap:
$ npm install jquery bootstrap --save Then add these lines to angular-cli.json or angular.json (depending on your version of Angular)

Add the needed scripts in your index.html. Be careful though as you’ll download these templates each time you reload the page.
