Control Plane Deployment Example

Control Plane offers a viable, cost-saving alternative to Heroku, especially when using the cpflow gem to deploy to Control Plane.

ShakaCode recently migrated HiChee.com to Control Plane, resulting in a two-thirds reduction in server hosting costs!

See doc in ./.controlplane/readme.md for how to easily deploy this app to Control Plane.

The instructions leverage the cpflow CLI, with source code and many more tips on how to migrate from Heroku to Control Plane in https://github.com/shakacode/heroku-to-control-plane.

React on Rails Pro and ShakaCode Pro Support

React on Rails Pro provides Node server rendering and other performance enhancements for React on Rails.

2018-09-11_10-31-11

For more information, see the React on Rails Pro Docs.

  • Optimizing your front end setup with Webpack v5+ and Shakapacker for React on Rails including code splitting with loadable-components.
  • Upgrading your app to use the current Webpack setup that skips the Sprockets asset pipeline.
  • Better performance client and server side.

ShakaCode can also help you with your custom software development needs. We specialize in marketplace and e-commerce applications that utilize both Rails and React. We can even leverage our code for HiChee.com for your app!

See the ShakaCode Client Engagement Model article to learn how we can work together.

Table of Contents

Demoed Functionality

  • Example of using the react_on_rails gem for easy react/webpack integration with Rails.
  • Example of React with CSS Modules inside of Rails using Webpack as described in Smarter CSS builds with Webpack.
  • Example of enabling hot reloading of both JS and CSS (modules) from your Rails app in development mode. Change your code. Save. Browser updates without a refresh!
  • Example of React/Redux with Rails Action Cable.
  • Example of Rails 7 with ReactJs/Redux/React-Router with Webpack and ES7.
  • Enabling development of a JS client independently from Rails using the Webpack Dev Server. You can see this by starting the app and visiting http://localhost:4000
  • Enabling the use of npm modules and Babel with a Rails application using Webpack.
  • Easily enable retrofitting such a JS framework into an existing Rails app. You don't need a brand new single page app!
  • Example setting up Ruby and JavaScript linting in a real project, with corresponding CI rake tasks.
  • Enabling the i18n functionality with react-intl.

Technologies involved

See package.json and Gemfile for versions

  1. react_on_rails gem
  2. React
  3. Redux
  4. react-router
  5. react-router-redux
  6. Webpack with hot-reload (for local dev)
  7. Babel transpiler
  8. Ruby on Rails 7 for backend app and comparison with plain HTML
  9. Heroku for Rails 7 deployment
  10. Deployment to the ControlPlane
  11. Turbolinks 5
  12. Tailwind CSS

Basic Demo Setup

Prerequisites

  • Node v22.3.0 or above. Be sure that you have Node installed! We suggest using nvm and running nvm list to check the active Node version. See this article Updating and using nvm.
  • Ruby 3.3.3 or above
  • Postgres v9.2 or above
  • Redis. Check that you have Redis installed by running which redis-server. If missing and on MacOS, install with Homebrew (brew install redis)
  • Yarn.

Setup

  1. git clone [email protected]:shakacode/react-webpack-rails-tutorial.git
  2. cd react-webpack-rails-tutorial
  3. bundle install
  4. yarn
  5. rake db:setup
  6. rails start

Basic Command Line

  • Run all linters and tests: rake
  • See all npm commands: yarn run
  • To start all development processes: foreman start -f Procfile.dev
  • To start only all Rails development processes: foreman start -f Procfile.hot

Rails Integration

We're now using Webpack for all Sass and JavaScript assets so we can do CSS Modules within Rails!

  • Production Deployment: heroku-deployment.md.
    • Configure Buildpacks 
      heroku buildpacks:set heroku/ruby --app your-app
heroku buildpacks:add --index 1 heroku/nodejs --app your-app
heroku buildpacks:set --index 3 https://github.com/sreid/heroku-buildpack-sourceversion.git --app your-app

Testing

  • See Yak Shaving Failing Integration Tests with React and Rails

  • Be sure to see Integration Test Notes for advice on running your integration tests.

  • Testing Mode: When running tests, it is useful to run foreman start -f Procfile.spec in order to have webpack automatically recompile the static bundles. Rspec is configured to automatically check whether or not this process is running. If it is not, it will automatically rebuild the webpack bundle to ensure you are not running tests on stale client code. This is achieved via the ReactOnRails::TestHelper.configure_rspec_to_compile_assets(config) line in the rails_helper.rb file. If you are using this project as an example and are not using RSpec, you may want to implement similar logic in your own project.

Webpack

Converted to use Shakapacker webpack configuration.

Additional Resources

Sass, CSS Modules, and Tailwind CSS Integration

This example project uses mainly Tailwind CSS for styling. Besides this, it also demonstrates Sass and CSS modules, particularly for some CSS transitions.

We're using Webpack to handle Sass assets so that we can use CSS modules. The best way to understand how we're handling assets is to close follow this example. We'll be working on more docs soon. If you'd like to give us a hand, that's a great way to learn about this!

For example in client/app/bundles/comments/components/CommentBox/CommentBox.jsx, see how we use standard JavaScript import syntax to refer to class names that come from CSS modules:

import css from './CommentBox.module.scss';

export default class CommentBox extends React.Component {
  render() {
    const { actions, data } = this.props;
    const cssTransitionGroupClassNames = {
      enter: css.elementEnter,
      enterActive: css.elementEnterActive,
      exit: css.elementLeave,
      exitActive: css.elementLeaveActive,
    };
  }
}

Fonts with SASS

The tutorial makes use of a custom font OpenSans-Light. We're doing this to show how to add assets for the CSS processing. The font files are located under client/app/assets/fonts and are loaded by both the Rails asset pipeline and the Webpack HMR server.

Process management during development

bundle exec foreman start -f <Procfile>
  1. Procfile.dev: Starts the Webpack Dev Server and Rails with Hot Reloading.
  2. Procfile.static: Starts the Rails server and generates static assets that are used for tests.

Contributors

The Shaka Code team!, led by Justin Gordon, along with with many others. See contributors.md

RubyMine and WebStorm

Special thanks to JetBrains for their great tools: RubyMine and WebStorm. Some developers of this project use RubyMine at the top level, mostly for Ruby work, and we use WebStorm opened up to the client directory to focus on JSX and Sass files.

Hiring

We're looking for great developers that want to work with Rails + React (and react-native!) with a remote-first, distributed, worldwide team, for our own products, client work, and open source. More info here.

Thank you from Justin Gordon and ShakaCode

Thank you for considering using React on Rails.

Aloha and best wishes from the ShakaCode team!
