Stimulus generator for rails

This is generator for Stimulus on Rails application with Webpacker.

Add to your Gemfile:

gem 'stimulus-generator-rails'

Add this code to your webpacker's entrypoint javascript file:

import { Application } from "stimulus"
import { definitionsFromContext } from "stimulus/webpack-helpers"

const application = Application.start()
const context = require.context("../javascripts/controllers", true, /\.js$/)
application.load(definitionsFromContext(context))

$ rails g stimulus CONTROLLER_NAME [action action]

# e.g.
$ rails g stimulus books index edit

This generator will create javascript and stylesheet into webpacker's source_entry_path/../javascripts/controllers and source_entry_path/../stylesheets. So if you set source_entry_path app/webpacker/entrypoint, you will see file structure like this:

app/webpacker
├── entrypoint
│   └── application.js
├── images
├── javascripts
│   └── controllers
│       └── books
│           └── index_controller.js
└── stylesheets
    └── books.scss
