graphql-compose-toolkit

Opinionated wrapper for GraphQL Compose Mongoose that provides an API controller factory.

Use an easy to read declarative style to build your GraphQL controllers for Mongoose Models.

Installation

This utility is eventually meant to be used as a NPM package, however there currently exists an issue with GraphQL Compose that is preventing this from working properly.

For now, copy the entire src folder into your project, make sure you have the peer dependencies installed if you don't already and import and call the makeGQLComposeToolKit function.

NPM:

npm install graphql-compose graphql-compose-mongoose ramda

Yarn:

yarn add graphql-compose graphql-compose-mongoose ramda

Usage

Example with controller factory, a central controller registry, and multiple controllers

Controller Factory Setup

import { SchemaComposer } from 'graphql-compose';
import { makeGQLComposeToolKit } from './graphql-compose-toolkit';

export const schemaComposer = new SchemaComposer();

export const { 
  gqlComposeMoongoosePipeline,
  getModelTC,
  addSchema,
  addSchemas,
 } = makeGQLComposeToolKit({
  schemaComposer
});

Building a simple controller

import { PersonModel } from './models';
import { myMiddleware } from './middleware';
import { 
  gqComposeMongoosePipeline 
} from './controllerFactory';

// building a basic controller using the configured pipeline function
export const PersonController = graphqlComposePipeline({
  Model: PersonModel,
  name: 'Person',
  useStandardQueryResolvers: true,
  useStandardMutationResolvers: true,
  commonMiddleware: [myMiddleWare],  
});

import { CompanyModel } from './models';
import { myMiddleware } from './middleware';
import { 
  gqComposeMongoosePipeline 
} from './controllerFactory';

// building a basic controller using the configured pipeline function
export const CompanyController = graphqlComposePipeline({
  Model: CompanyModel,
  name: 'Company',
  useStandardQueryResolvers: true,
  useStandardMutationResolvers: true,
  commonMiddleware: [myMiddleWare],  
});

Central Controller Registry

import {    
  addSchemas  
} from './controllerFactory';

import { PersonController, CompanyController } from './controllers';

addSchemas([
  PersonController,
  CompanyController
]);
