如何在 angular 项目中包含 popper.js 和 bootstrap.js

Question

I am using angular with openlayers and I am following the example posted below in the link:

        https://openlayers.org/en/latest/examples/overlay.html

the aforementioned link provide the following information in order to work with the popover:

Things to know when using the popover plugin:
Popovers rely on the 3rd party library Popper.js for positioning. You must include popper.min.js before bootstrap.js or use bootstrap.bundle.min.js / bootstrap.bundle.js which contains Popper.js in order for popovers to work!

please let me know how to include

popper.js 

and

bootstrap.js 

so i can work with the popover function and get it working.

Answer 1

You can add node_modules/dist/css/boostrap.min.css in styles under the build section of angular.json file BEFORE src/styles.css . You can download the bootstrap from the npm package npm install bootstrap

In order to work with the pop ups you can add the bundle file of bootstrap node_modules/bootstrap/dist/js/bootstrap.bundle.min.js in the scripts under the build section of the same file.

EDIT: You have to download JQuery and add it to your scripts section as well.

for external JavaScript or any file that you want to implement on angular. you have to set path for that files on angular.json file

for angular older version need set path on .angular.cli.json

Note :- after changes on angular.json file, you have to recompile or restart project.

you can import files into index.html file.
