A complete clone of whatsapp web using React Js as the front end and Node Js as the back end. MongoDB is used as the database. Use of 3rd party library is minimum. Redux is used for managing the entire state and redux saga for handling side effects. AWS S3 is used for data storage and retrieval.

a) Front End: React Js, Redux, Redux-Saga, Axios, Socket Client, Peer JS, React Spring.
b) Back End: Node Js, Redis, Cluster, Socket.io, Mongo DB, Peer and Express, AWS S3.

Make sure to create a IAM user with the required policies. For this project I've used my custom policy:

  npm i && npm run dev

• In whatsapp-client run:
  npm i && npm start

A modified version of WhatsApp Web where you can create global rooms and chat in realtime. It uses firebase for google authentication and uses its NoSQL and SQL hybrid as database. React Context API is used for managing global state.
