Add Webpack to a Rails 4.2 app with the Webpacker gem
Add gem:
gem 'webpacker', '~> 2.0'
bundle install
Run either normal or React-ready install:
rake webpacker:install
rake webpacker:install:react
Add jQuery if you still need it:
yarn add jquery
Add expose-loader:
yarn add expose-loader -D
Change config/webpack/configuration.js:
module.exports = {
settings,
env,
loadersDir,
output,
rules: [{
test: require.resolve('jquery'),
use: [{
loader: 'expose-loader',
options: '$'
}]
}]
}
Cheers,
Ryan
