Validation and auto-completion for hand-typed info objects in resolvers

[jhalborg]

As discussed in this forum post

I'm wondering if there is any way to validate handwritten queries passed instead of info in Prisma resolvers against the Prisma DB schema? In the following example, I have a User model that has a reference to a UserCredentials model. In the login resolver, I will find the UserCredential by the passed email, and find the relevant User's ID from a handwritten query:

resolve: async (parent, { email, password }, ctx, info) => {
    const userCredentials = await ctx.db.query.userCredential({ where: { email } }, `{id password user {id}}`);
    ...
}

I would like to check queries like that against the schema - how would I do that? 😃

And even better - how could you get auto completion in VSCode for these strings?

PS: The idea came from the HowToGraphQL tutorial project (https://github.com/howtographql/graphql-js/blob/master/src/resolvers/Mutation.js#L34)

Just as there's an option to inspect the DB from a playground as it runs on a different port than the app, would it be possible to have another key in the graphqlconfig.yml that listens to that port and validates gql tags or .graphql files against that, perhaps alongside a regular .graphql app instance? Say, something like this:

{
  "projects": {
    "app": {
      "schemaPath": "schema.graphql",
      "includes": ["**/*.{graphql,ts,tsx}"],
      "extensions": {
        "endpoints": {
          "dev": "http://localhost:4000/graphql"
        }
      }
    },
    "db": {
      "schemaPath": "schema.graphql",
      "includes": ["**/*.{graphql,ts,tsx}"],
      "extensions": {
        "endpoints": {
          "dev": "http://localhost:4001/db"
        }
      }
    }
  }
}
