GraphQL is a server-oriented query and execution environment for application programming interfaces (APIs) whose priority is to provide exactly the data that clients request and nothing more.
GraphQL
In this API we have a CRUD of users and posts using MongoDB database.
- Install dependencies with yarn install
- Run application with yarn dev
- Access the server at http://localhost:4000
