| # API | |
| The Spectrum API is a Node.js web server based on Express.js and GraphQL. It's also houses a websocket server for all of our subscription needs. | |
| ## Structure | |
| This server follows a GraphQL-first philosophy. That means we design the GraphQL schema first and then start implementing business logic. This is great because it gives us a clear separation of concerns (business logic vs. schema), and it's how Facebook recommends to use GraphQL. | |
