There are two different services, the backend is built using nodeJS. This can be run by
npm run server
The client is a ReactJS application generated by create-react-app. To run the client application
npm run client
Now the react application can be used from http://localhost:3001
Note: npm install has to be run inside client folder as well as the folder containing server index.js file.
To run both server and client application
npm run dev
Run the build command to generate the static files to serve
npm run build --prefix client
Note: Here the socket port should be the same as the port number server is hosted
Run the node server using the command
PORT=80 node index.js
