This chapter has been a dense and intensive boot camp about the GraphQL world. Now, you have a strong base theory to understand the GQL ecosystem and how it works under the hood of every GQL adapter.
We have built a GraphQL server from zero using Fastify and Mercurius. All the knowledge gained from this book’s Chapter 1 is valid because a Fastify application doesn’t have any more secrets for you.
On top of your Fastify knowledge, you are able to define a GQL schema and implement its resolvers. We have solved the N+1 problem and now know the proper steps to manage it and create a fast and reliable application.
You finally have a complete toolkit at your disposal to create great APIs. You are ready to improve your code base even further by adopting TypeScript in the next chapter!
