GQLify Open Source

December 5, 2018

Hi everyone! We are so happy to show you our new open source project - GQLify. After canner released, we spend much time on how to save developer time on building GraphQL projects. Today, we launched a new open source project called "GQLify"! With GQLify, only thing you need to do is define the Data Model and GQLify will generate APIs for you.

GQLify helps you do following things:

• Auto-generate GraphQL Schema
• Support multiple data sources (e.g. Firebase, Firestore, MongoDB, ...)
• Auto-generate APIs for different data sources.
• Auto-generate Query functions
• Auto-generate Mutation functions
• Handle relationship between data model (one-to-one, one-to-many, many-to-many)
• Auto-generate Apollo Server configuration

Learn more Why GQLify.

• 👉 GQLify documentation: https://www.gqlify.com/docs/intro

Quick Demo

1. Define your schema in demo.graphql

type User @GQLifyModel(dataSource: "memory", key: "users") {
  id: ID! @unique @autoGen # auto generate unique id
  username: String!
  email: String
  books: [Book!]! # User-Book: one-to-many
}

type Book @GQLifyModel(dataSource: "memory", key: "books") {
  id: ID! @unique @autoGen # auto generate unique id
  name: String!
  author: User!
}

2. Setup GQLify with Apollo Server in index.js

const { Gqlify, MemoryDataSource } = require('@gqlify/server')
const { ApolloServer } = require('apollo-server');

// Read datamodel
const sdl = readFileSync(__dirname + '/demo.graphql', { encoding: 'utf8' });

// mock default data
const defaultData = {
  users: [
    {id: '1', username: 'Alice', email: 'alice@gmail.com'},
    {id: '2', username: 'Bob', email: 'bob@gmail.io'},
  ],
  books: [
    {id: '1', name: 'book1', userId: '1'},
    {id: '2', name: 'book2', userId: '2'},
  ],
};

// construct gqlify
const gqlify = new Gqlify({
  // provide datamodel to gqlify
  sdl,

  // provide data-sources map to GQLify,
  // so GQLify would know how to create data-source for each model
  dataSources: {
    memory: args => new MemoryDataSource(defaultData[args.key]),
  },
});

// GQLify will provide graphql apis & resolvers to apollo-server
const server = new ApolloServer(gqlify.createApolloConfig());

// start server
server.listen().then(({ url }) => {
  console.log(`🚀 Server ready at ${url}`);
});

3. Start server!

$ node index.js

Now, GQLify console your data model and relationship.

Open http://localhost:4000, and you can enjoy GQLify.
