graphene-sequelize

Graphene-JS

A Sequelize integration for Graphene-JS.

Installation

For installing Graphene Sequelize, just run this command in your shell

npm install --save graphene-sequelize
# or
yarn add graphene-sequelize

Examples

Here is a simple Sequelize model:

import * as Sequelize from "sequelize";

const UserModel = sequelize.define("user", {
  name: Sequelize.STRING,
  lastName: Sequelize.STRING
});

To create a GraphQL schema for it you simply have to write the following:

import { ObjectType, Field, Schema } from "graphene-js";
import { SequelizeObjectType } from "graphene-sequelize";

@SequelizeObjectType({ model: UserModel })
class User {
  // Fields will be populated automatically from the sequelize
  // model, and we can also add extra fields here.
}

class Query {
  @Field([User])
  users() {
    return UserModel.findAll();
  }
}

schema = new Schema({ query: Query });

Then you can simply query the schema:

const query = `
query {
  users {
    name,
    lastName
  }
}
`
result = await schema.execute(query)
