Realtime Calculator using React, Express and Socket-io
This is a realtime calculator that can be used to share calculations with friends also using the webapp. It uses React (bootstrapped with create-react-app) on the Front End. On the backend, I used Express and Socket to handle the realtime communication.
Hosting
It's available at https://realtime-calcc.herokuapp.com/
Heroku restarts servers every 24 hours, so the previous calculations which are stored on the backend are lost. This can be fixed by backing up calculations to a database
Building locally
