Graphql-Sequelize-Generator

Graphql-Sequelize-Generator (GSG) is a set of tools that will allow you to easily generate a graphql API from your sequelize models.

What can I do with GSG?

The tools provided by this library will allow you to:

• Query any models and associated ones through Graphql.

• Auto-generate create/update/delete mutations.

• Define before/after hooks and all resolvers, including the mutations.

• Easily create custom mutations.

• Get an integrated interface to test your Graphql API.

• Counts for each model can also be generated.

• Subscriptions auto-generated for mutations.

• Add custom fields/resolvers/subscriptions on auto-generated types.

• Easily add fully custom endpoints

Getting started

Add the lib and the peer dependencies:

$ yarn add graphql-sequelize-generator graphql sequelize graphql-sequelize

Caution: GSG requires at least Node v9.11.2 or greater as it is using async/await.

Then you will be ready to add a GraphQL API to your express server.

const express = require('express')
const {
  generateModelTypes,
  generateGraphqlExpressMiddleware
} = require('graphql-sequelize-generator')
const models = require('./models')

const types = generateModelTypes(models)

graphqlSchemaDeclaration.user = {
  model: models.user,
  actions: ['list', 'create']
}

const server = generateApolloServer({
  graphqlSchemaDeclaration,
  types,
  models
})

const app = express()
server.applyMiddleware({
  app,
  path: '/graphql'
})
