Usage 💻

npm install loopback-graphql-relay

Add the loopback-graphql-relay component to the server/component-config.json:

"loopback-graphql-relay": {
    "path": "/graphql",
    "graphiqlPath": "/graphiql",
    "subscriptionServer": {
      "disable": false,
      "port": 5000,
      "options": {},
      "socketOptions": {}
    },
    "viewer": {
      "AccessTokenModel": "CustomAccessToken",
      "relation": "user",
      "UserModel": "Account"
    }
  }

Requests will be posted to path path. (Default: /graphql);

Graphiql is available on graphiqlPath path. (Default: /graphiql);

Apollo's Subscription Server can be customised by passing subscriptionServer configuration. More information can be found at SubscriptionServer Docs.

Inspiration 🙌

This repository originally started as a fork of the loopback-graphql project by Tallyb. But due to considerable change in the way query end points are created, this repository is maitained as an independant project.
