In a Ruby on Rails application, how can we require or import a package which was not installed via npm or yarn, but via bundle?
I tried:
//= require package-name
But that doesn't seem to work with webpacker.
require("package-name") doesn't work either (because it is not found in node_modules).
For normal Rails environment, you can use normal directory path if you want to require some files.
Suppose your assets folder looks like this
├── application.js
└── something.js
and you want to require something.js then you just need to write
//= require ./something.js
to your application.js
For a package that you manually place somewhere, then you have to add the place of packages to Rails.application.config.assets.paths
If you are using Rails v5, you can check the config/initializers/assets.rb to see the magic of loading node_modules happened
