Try ERPNext Buy Support Partners Foundation

Uncaught ReferenceError: require is not defined in custom app

when i try to load quill mention cdn ,i am getting this error require is not defined in custom app

$.getScript(“https://cdn.jsdelivr.net/npm/quill-mentions@0.2.4/src/js/mentions.min.js”,
});

can not import also

please guide the correct procedure to import package in custom app

Based on this environment setup code

My guess is to focus on how this applies in your particular case apps/your_custom_app/package.json

These two apps/frappe/package.json and apps/erpnext/package.son will give you clues too.

Perhaps this tutorial example will help https://classic.yarnpkg.com/en/docs/creating-a-package/

edit: This could be a clue or tip How to import a .js module in Frappe?

and also this How to add a node module to a custom app?
