Mongoose (MongoDB) adapter for the graffiti GraphQL ORM.

graffiti-mongoose generates GraphQL types and schemas from your existing mongoose models, that's how simple it is. The generated schema is compatible with Relay.

For quick jump check out the Usage section.

npm install graphql @risingstack/graffiti-mongoose --save

Check out the /example folder.

cd graffiti-mongoose
npm install # install dependencies in the main folder
cd example
npm install # install dependencies in the example folder
node . # run the example application and open your browser: http://localhost:8080

This adapter is written in ES6 and ES7 with Babel but it's published as transpiled ES5 JavaScript code to npm, which means you don't need ES7 support in your application to run it.

import mongoose from 'mongoose';

var UserSchema = new mongoose.Schema({
  name: {
    type: String
  },
  age: {
    type: Number,
    indexed: true
  },
  friends: [{
    type: mongoose.Schema.Types.ObjectId,
    ref: 'User'
  }]
});

var User = mongoose.model('User', UserSchema);

import {getSchema} from '@risingstack/graffiti-mongoose';
import graphql from 'graphql';

var schema = getSchema([User]);

var query = `{
    users(age: 28) {
      name
      friends(first: 2) {
        egdes {
          cursor
          node {
            name
            age
          }
        }
        pageInfo {
          startCursor
          endCursor
          hasPreviousPage
          hasNextPage
        }
      }
    }
  }`;

graphql(schema, query)
  .then((result) => {
    console.log(result);
  });

• Number
• String
• Boolean
• Date
• [Number]
• [String]
• [Boolean]
• [Date]
• ObjectId with ref (reference to other document, populate)
• more types coming soon...

• query
  • singular: for example user
  • plural: for example users
  • node: takes a single argument, a unique !ID, and returns a Node

• indexed fields
• "id" on singular type
• array of "id"s on plural type

Which means, you are able to filter like below, if the age is indexed in your mongoose model:

users(age: 19) {}
user(id: "mongoId1") {}
user(id: "relayId") {}
users(id: ["mongoId", "mongoId2"]) {}
users(id: ["relayId1", "relayId2"]) {}
