twitter search React Project with Node Express Backend

Example on using create-react-app with a Node Express Backend

Usage

Install nodemon globally

npm i nodemon -g

Install server and client dependencies

yarn
cd client
yarn

To start the server and client at the same time (from the root of the project)

yarn dev

How this works

The key to use an Express backend with a project created with create-react-app is on using a proxy. We have a proxy entry in client/package.json

"proxy": "http://localhost:5000/"

This tells Webpack development server to proxy our API requests to our API server, given that our Express server is running on localhost:5000
