Exit Asset Pipeline, Enter Webpack
Webpack is a module bundler. It can bundle all JS files for usage in the browser, but can also transform / bundle / package any resource or frontend asset.
The NPM ecosystem is huge, and Webpack makes it available in the simplest way possible.
Webpack can support every modern JS app, using ES6 or CommonJS modules, or both, create a single or multiple bundles, and in general can be customized to accomplish any application requirement.
The frontend assets on this repository are placed on a more accessible directory, at
front/css, rather than
At any point, migration to a different backend (for example NodeJS) can be seamless since Webpack is running as a stand-alone bundler, there's absolutely no dependence to the Asset Pipeline or any other framework-specific module.
It's recommended to use Ruby 2.5.0 and NodeJS 10.15.x.
# install bundler if not available gem install bundler # install gem dependencies bundle install # install npm dependencies npm install # create the postgres databases # update config/database.yml details if needed rake db:create # generate assets for development npm run webpack # start server rails s
npm run webpack
Builds the assets for development mode.
npm run webpack:watch
Builds the assets for development mode, and rebuilds on every detected change.
npm run webpack:production
Builds the assets for production mode, output files are hashed.
Load assets in production from a custom root directory or URL
By default JS/CSS assets are being served from the
public/dist directory. However in production it may be needed to serve assets from a CDN or an S3 bucket etc.
Simply override the
Rails.application.config.assets.root_path property on the production environment to accomplish it.
Of course during the deployment script and after the
npm run webpack-production command,
public/dist/* output files should be copied to the target dir or infrastructure.
Run in Docker (optional)
Repository contains a basic Dockerfile for running the app in production mode.
Assets should be compiled first using webpack outside of the container.
