Hackernews in Nodejs and GraphQL

In this project, I learned how to build a GraphQL server from scratch. The stack is Node.js, graphql-yoga and Prisma.

Technologies used:

• Written in Node.js as its a simple yet powerful technology to use.
• Making use of graphql-yoga as its a fast and simple GraphQL server library built on top of Express.js. It comes with several features, such as out-of-the-box support for GraphQL Playgrounds and realtime GraphQL subscriptions.
• The resolvers of the GraphQL server are implemented using Prisma Client ,which is responsible for database access.
• Using sqlite as the database.

Features Implemented

• Get links posted as feeds.
• Support pagination and sorting on feeds.
• Support filtering on feeds.
• Authentication using email and password with JWT support.
• Vote on the links posted.
• Update links posted.
• Delete links posted.
• Receive notification in realtime on recent links added.
• Receive notification in realtime on recent votes made.
