REST API to GraphQL Example

This code is an example of how to migrate a traditional REST API to GraphQL using the API of jsonplaceholder as a reference.

Requirements

• Node 7.6+
• MongoDB
• Yarn

Installation

Make sure to have mongodb installed.

To start the mongodb server run:

$ mongod

After clonning the project run:

$ yarn install // install project dependencies
$ yarn build   // transpile code from typescript to js (ES6)
$ yarn loader  // populate mongodb with data from jsonplaceholder API
$ yarn start   // start koa server with graphql

An express server will be up and running in the port 3000.

Open your browser and go tohttp://localhost:3000/graphql to start playing with the graphiql GUI

$ yarn build:watch
