Rails 5.1 example app leveraging webpack and react with various additional goodies such as linting, react hot reloading and css hot reloading.
You'll need a few dependencies to start the app:
Once you have the dependencies installed, clone and run the example with:
$ git clone git@github.com:madrailers/webpack-on-rails.git
$ cd webpack-on-rails
$ bundle install
$ yarn install
$ bundle exec foreman start
The new webpacker integration in Rails 5.1 has a nontrivial number of moving parts that you'll eventually touch as you build out your front-end pipeline.
First, check out the config/webpack directory. Trace through the includes
starting with config/webpack/configuration.js.
Second, look at the loaders that are currently configured in the
config/webpack\loaders directory.
Third, take a look at the entry points in app/javascript/packs. These are
the files that are referenced from Rails views that import the bundles created
by webpack.
Fourth, check out how we import the bundles in
app/views/layouts/application.html.erb. In that file we're importing both the
index.jsx bundle as well as the hot-reloadable index.css.
