This is the Express/GraphQL/Apollo server, designed and configured for the Chat Application
This is an Express/GraphQL server with a built-in small SQLite database. It uses JSON Web Token for user authentication. Another feature is support for the WebSocket protocol, which enables bidirectional communication between the client and server through a single persistent TCP connection.
This server also uses GraphQL Subscriptions, which, together with the WebSocket protocol, allows us to receive fresh data instantly without making separate requests.
Both the client and server can send messages to each other simultaneously, making it ideal for real-time applications.
This server is only part of the application, the second part (the client) is located at this repo: Chat client
The app in this repo is deployed at https://render.com, hosting public URL: https://chat-app-server-0qdt.onrender.com/graphql
But you can use this server manually on your local machine
