This issue is tracking progress on implementing native GraphQL layer making it easy to build GraphQL APIs in LoopBack.

- Package name: [`@loopback/graphql`](https://www.npmjs.com/package/@loopback/graphql)
- Example app: [`@loopback/example-graphql`](https://github.com/strongloop/loopback-next/tree/master/examples/graphql)
- Docs: [Creating GraphQL APIs](https://loopback.io/doc/en/lb4/GraphQL.html)

## Progress

Stability: ⚠️Experimental⚠️

- [x] #5545 added the initial implementation of native GraphQL layer, built using [type-graphql](https://github.com/MichalLytek/type-graphql).
- [x] #6313 added support for GraphQL subscriptions
- [x] #6313 improved graphql configuration and subscriptions
