React + Sinatra Starter

for Heroku deployment

OVERVIEW

This is a simple starter to get you up and running with React & Sinatra. This is intended to provide:

• a lightweight Webpack config (for development and production)
• some helpful tooling for development workflow
• Heroku-ready deployment setup

WHY REACT + SINATRA?

This starter has been a surprisingly valuable tool. Sinatra provides a really simple web framework for serving our React frontend. You can quickly add some API endpoints (and/or GraphQL) and connect ActiveRecord. We get all the benefits of using Ruby's simple syntax and predicability, and React's powerful rendering.

UP & RUNNING

• Clone the repo
• Install Ruby dependencies: $ bundle install
• Install JS dependencies: $ npm install or $ yarn
• Fire up a dev server: $ npm run dev or $ yarn dev
• Visit http://localhost:8080 in your browser

WHATS HAPPENING?

When you run npm run dev, webpack is transpiling all your JS and CSS into a ghost file, lib/app/public/bundle.js. It then serves up the HTML file, lib/app/views/index.html on a ghost Express server on port 8080.

BUT WAIT, WE'RE NOT USING A SINATRA SERVER?

That's correct. To use the Puma server for Sinatra with the transpiled assets, take a look at the Production Build section

LINTING

To run the linter once:

$ npm run lint
// or
$ yarn lint

To run the watch task:

$ npm run lint:watch
// or
$ yarn lint:watch

TESTING

To run the tests:

$ npm test
// or
$ yarn test

PRODUCTION BUILD

• run $ npm run build or $ yarn build
• run ruby lib/app.rb (We're using Puma by default)

This creates a transpiled asset file (bundle.js) of your JS and CSS in the lib/app/public/ directory. This is great for production, but not so hot for development workflow as you would need to transpile every time you made a change to the JS.

DEPLOYING TO HEROKU

This app is set up for deployment to Heroku!

This assumes you have already have a Heroku account and have the Heroku CLI installed

🚨 Be sure to run the build script before deploying. 🚨

$ heroku login
$ heroku create -a name-of-your-app
$ git push heroku master
$ heroku open

If you're unfamiliar with Heroku deployment (or just need a refresher), they have a really great walkthrough here.
