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.

It's a very good fit for POCs and MVPs, while also scaling pretty well thanks to dataloader-sequelize.

What can I do with GSG?

The tools provided by this library will allow you to:

• Query any model defined in your app 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 on auto-generated types.
• Easy integration with dataloader-sequelize

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 with only a few lines of code:

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