This is the most simple Boilerplate in the world for starting projects with React on the front end with Express server and server render.
Before starting a React project just make sure you actually need all that fire power. If not maybe just use Vue?
Install the dependencies
npm install
Compile with webpack running the script with the following command
npm run dev
Start the server
npm start
Run production build of React with webpack command
webpack -p
Create Heroku staging with Heroku command line (optional)
heroku create --remote staging
Push Heroku staging
git push staging master
Create Heroku production
heroku create --remote production
Push Heroku production
git push production master
