graphql-mongodb-resolver

Resolvers generator for GraphQL and MongoDB

Concept

var express = require('express');
var graphqlHTTP = require('express-graphql');
var { buildSchema } = require('graphql');
var resolver = require('graphql-mongodb-resolver')
var MongoClient = require('mongodb').MongoClient

var url = 'mongodb://localhost:27017/myproject';

var schema = buildSchema(`
  type Query {
    hello: String
  }
`);

MongoClient.connect(url, function(err, db) {
    var app = express();
    app.use('/graphql', graphqlHTTP({
      schema: schema,
      rootValue: resolver(schema, db),
      graphiql: true,
    }));
    app.listen(4000, () => console.log('Now browse to localhost:4000/graphql'));
  db.close();
});

No need for writing resolvers. User should only define GraphQL scheme.
