How to autoload types to graphql resolver

[ziimakc]

I use apollo server with context type:

server.ts:

const prisma = new PrismaClient()

export type Ctx = {
  db: PrismaClient
}

How can i autoload and bind Ctx type to ctx in resolver?

const Query = objectType({
  name: 'Query',
  definition(t) {
    t.field('test', {
      type: 'Test',
      resolve: async (_root, _args, ctx) => {
        const [time] = await ctx.db.$queryRaw(`SELECT now();`)

        return { id: 1, time: time.now.toString() }
      },
    })
  },
})

export const schema = makeSchema({
  types: [Query, Test],
  typegenAutoConfig: {
    sources: [
      {
        alias: 'ctx',
        source: path.join(__dirname, 'backend', 'apollo', 'server.ts'),
        typeMatch: () => new RegExp(`Ctx`),
      },
    ],
  },
})

Without typegenAutoConfig ctx type is any. With typegenAutoConfig its type is {}.

It seems there is problem with path when using next.js, so solution is:

  typegenAutoConfig: {
    sources: [
      {
        alias: 'types',
        source: path.join(process.cwd(),  'backend', 'apollo', 'server.ts'),
      },
    ],
    contextType: 'types.Ctx',
  },
