Graphitejs: Create GraphQL Servers with Node.js

Graphitejs

Framework NodeJS for GraphQl

GraphiteJS is a NODE.JS Framework for building GraphQL schemas/types fast, easily and with scalability.

  • Easy to use: GraphiteJS make easy GraphQL in NodeJS without effort.
  • Any Front: GraphiteJS support any front library.
  • Data agnostic: GraphiteJS supports any kind of data source.

Install


npm i @graphite/server --save

yarn add @graphite/server

on your index file:


import { Graphite } from '@graphite/server'

main = async () => {
  const graphite = await Graphite()
}

main()

and that's all, you have running the graphqli tool on the port 4000 by default.

How to use

After install @graphite/server you have to create your first model. We recommend creating a folder called models and follow the pattern matching the filename with the Type name.

Types


import { GraphQL } from '@graphite/server'

export const Developer = GraphQL('Developer')({
   // the value always have to be an array first arg is the type, the second arg is an optional comment
  name: ['String!', 'Your name is required'],
  age: ['Int'],
  isGreatDeveloper: ['Boolean']
})

So, now you need to pass this model to the Graphite Server

on index.js


import { Graphite } from '@graphite/server'
import { Developer } from './models/Developer'

main = async () => {
  await Graphite({ models: [Developer] })
}

main()

Queries


import { GraphQL } from '@graphite/server'

export const Developer = GraphQL('Developer')({
  name: ['String!', 'Your name is required'],
  age: ['Int'],
  isGreatDeveloper: ['Boolean'],

  Query: {
    'developer: Developer': () => ({ name: 'Your name' }),
    'developers: [Developer]': () => ([{ name: 'Your name' }]),
  }
})

Mutations


import { GraphQL } from '@graphite/server'

export const Developer = GraphQL('Developer')({
  name: ['String!', 'Your name is required'],

  Mutation: {
    'createDeveloper(name: String): Developer': (_, { name, }) => ({ name }),
    'updateDeveloper(id: ID!, name: String): Developer': (_, { name }) => ({ name }),
    'removeDeveloper(id: ID!): Developer': (_, { name }) => ({ name }),
  },
})

Subscriptions


import { GraphQL, PubSub } from '@graphite/server'

const pubsub = new PubSub()
const DEVELOPER_ADDED = 'DEVELOPER_ADDED'

export const Developer = GraphQL('Developer')({
  name: ['String!', 'Your name is required'],

  Mutation: {
    'createDeveloper(name: String): Developer': (_, { name, }) => { 
      pubsub.publish(DEVELOPER_ADDED, { developerAdded: { name } })
      return { name }
    },
  },

  Subscription: {
    'developerAdded: Developer': {
      subscribe: () => pubsub.asyncIterator([DEVELOPER_ADDED]),
    },
  },
})

Relations


  // models/Repository.js
  const Repository = GraphQL('Repository')({
      name: ['String'],
      url: ['String'],
  })

  // models/GithubProfile.js
  const GithubProfile = GraphQL('GithubProfile')({
      url: ['String'],
  })

  // models/Developer.js
  const Developer = GraphQL('Developer')({
    name: ['String'],

    'respositories: [Repository]': () => [{ name: 'GraphiteJS', url: 'https://github.com/graphitejs/graphitejs' }],

    'githubProfile: GithubProfile': () => ({ url: 'https://github.com/wzalazar' }),

    Query: {
      'developer: Developer': () => ({ name: 'Walter Zalazar' }),
    },
  })

So, now you need to pass this model to the Graphite Server

on index.js


import { Graphite } from '@graphite/server'
import { Developer } from './models/Developer'
import { Repository } from './models/Repository'
import { GithubProfile } from './models/GithubProfile'

main = async () => {
  await Graphite({ models: [Developer, Repository, GithubProfile] })
}

main()
