Golang-Relay Starter Kit

This kit includes:

• a NodeJS app server: to serve the front-end written with react-relay
• a Golang GraphQL server: to serve the back-end graphql-go server that handles GraphQL queries
• a Babel transpiler workflow using webpack that you can use to get started building an app with Relay.

For a walkthrough, see the Relay tutorial.

Notes:

This is based on alpha version of graphql-go and graphql-relay-go. Be sure to watch both repositories for latest changes.

Installation

• Install dependencies for NodeJS app server

npm install

• Install dependencies for Golang GraphQL server

go get -v

Running

Start a local server:

npm start

The above command will run both the NodeJS app server and Golang GraphQL server concurrently.

• Golang GraphQL server will be running at http://localhost:8080/graphql
• NodeJS app server will be running at http://localhost:3000

Developing

JavaScript

Any changes you make to files in the js/ directory will cause the server to automatically rebuild the app and refresh your browser.

Golang

Schema data

Since Golang does not support loading package / module dynamically, remember to update the package import for schema data in:

• graphql.go
• scripts/updateSchema.go

For e.g

import (
  ...
  "github.com/sogko/golang-relay-starter-kit/data" // <--- update to package containing schema
)

Schema updates

If at any time you make changes to data/schema.go, stop the server, regenerate data/schema.json, and restart the server:

npm run update-schema
npm start

schema.json is needed by the JS code for ./build/babelRelayPlugin.js

Examples

• todomvc-relay-go - Port of the React/Relay TodoMVC app, driven by a Golang GraphQL backend

Feel free to submit a PR to add to this list.

TODOs

• Swap out express-graphql server with a Golang GraphQL server
• GraphQL schema definition in Golang
• Generate schema.json from schema definition for babel-relay-plugin
• Generate schema.graphql from schema definition
