• 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) => {},
           },
         };
