How to use cocoon gem in Rails 6

First: run

yarn add cocoon-js

Second: add to application.js

import 'cocoon-js'

There is an 'hack' on the cocoon page for this:

https://github.com/nathanvda/cocoon/issues/555

Updated Solution: Cocoon package has been release so one can easily use this with wepacker

Inside your Gemfile add the following:

gem "cocoon"

Add the componanion package

yarn add @nathanvda/cocoon 

and then in your app/javascripts/packs/application.js you should add

require("jquery")
require("@nathanvda/cocoon")

Old Solution:

There is this Pull Request on cocoon GitHub repository that worked perfectly for me.

Package.json is provided in this branch so we can use yarn or npm to install package by providing GitHub repo link.

yarn add github:nathanvda/cocoon#c24ba53

Cocoon package will install and you can check your package.json file.

"cocoon": "github:nathanvda/cocoon#c24ba53"

commit number #c24ba53 is important, make sure it is included in your package.json file

After this, you can import cocoon.js in application.js file.

import "cocoon";
