Building GraphQL Servers with Node.JS & Prisma
0 likes736 views
This document discusses building GraphQL servers with Node.js and Prisma. It introduces GraphQL and its benefits like querying exact data needs. It also outlines the three parts of a GraphQL server: the schema, resolver functions, and network layer. It then provides an example of building a clone of the Medium API from scratch in steps, starting with a minimal GraphQL server and adding database integration with Prisma and completing the API operations. The document encourages following along with the code examples provided in the GitHub repository. It also mentions Prisma is hiring.

- 10. 3 parts of a GraphQL server 1. Structure: The GraphQL schema 2. Behaviour: Resolver functions 3. Network Layer: Network, Middleware, …
- 11. 1) The GraphQL Schema • Strongly typed & written in GraphQL Schema Definition Language (SDL) • Defines API capabilities ( = contract for client-server communication) • Special root types: Query, Mutation, Subscription @nikolasburk
- 12. Example: Hello World SCHEMA @nikolasburk SERVER RESPONSEQUERY
- 13. Example: CRUD for User type @nikolasburk
- 14. 2) Resolver functions • Concrete implementation of the API • One resolver function per field in SDL schema • Query execution: Invoke resolvers for all fields in query @nikolasburk
- 16. Example: CRUD for User type @nikolasburk
- 17. 3) Network Layer • Based on `graphql-yoga` • Network configuration: port, endpoints, CORS, … • Middleware (analytics, logging, crash reporting,…) @nikolasburk
- 18. …putting it all together 1) SCHEMA 2) RESOLVERS 3) NETWORK LAYER x
- 19. Building a clone of the Medium API …from scratch • Queries • Retrieve a list of all posts (or filter for `title` or `content`) • Retrieve a single post by its `id` • Mutations • Create a new draft • Publish a draft • Delete any post by its `id` (published or draft) @nikolasburk

- 21. Steps @nikolasburk Step 0: Minimal GraphQL server Step 1: Extend API with query arguments Step 2: Complete API operations Step 3: Add database layer with Prisma and Prisma bindings Step 4: Complete API operations against the database
