GraphQL Subscriptions Spike Solution

Introduction

This project contains several servers and a React web client that demonstrate GraphQL subscriptions over WebSocket connections. The domain in the example app is that of a online blog, where you have posts and posts are associated with zero or more comments.

Implementation

Server

The spike solution consists of two different server implementations:

• graphql-subscriptions-apollo-express: Node.js which uses Apollo Server and Express modules.
• graphql-subscriptions-rails: Ruby on Rails 5.1 using the graphql-ruby gem.

Note that each server implements the same functionality, so you only need to run one server for the spike solution.

Web client

The GraphQL client is a React webapp which utilizes Apollo Client for the GraphQL connectivity to the backend servers.
