Learning lots from

• prisma 2 schema auto completion rocks! but it auto completes with PascalCase watch out for that!

• placing the prisma instance into the ApolloServer context is a good idea! it means that when we create our mutations and resolvers we have access to prisma via context e.g prisma.context.

• The real magic is when when combine the prisma autogenerated types with GraphQL Code Generator

  • We can tell the codegen also use a custom interface which defines the context.
  • overwrite: true schema: “http://localhost:4000” generates: src/generated/graphql.ts: plugins: - “typescript” - “typescript-resolvers” config: contextType: ../context#Context useIndexSignature: true

  • When then use the Resolvers types in our code like so, we have full prisma auto completion on the context argument.

  •  import { Resolvers } from "./generated/graphql";
    
       export const resolvers: Resolvers = {
         Query: {
           AllPosts: async (_, args, context) => {
           },
         },
         Mutation: {
           AddPost: async (_, args, context) => {},
           LikePost: async (_, args, context) => {},
         },
       };
