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


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 Creating a Package | Yarn

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?
