Why You Should Use Implementation-First to Build Your GraphQL Schema Erik Wrede fulfillmenttools

When we look at GraphQL server implementation approaches, you often see the discussion between code-first and schema-first as a schema building approach. What is overlooked is that Facebook actually built their Hack-based GraphQL server with implementation-first. This approach will infer the GraphQL schema from your code, and by extension from your business layer. In this talk, I will look at various implementations of implementation-first and explain why Facebook chose this approach to build their own GraphQL server and why it is actually the better approach in most projects.
