Documentation on makeSchema/typegenAutoConfig

[JulianaAmoasei]

I'm looking for documentation on the use of the sources property on typegenAutoConfig, but ended up with more doubts... The related page in the docs seems to be incomplete, as some sentences kind of end abruptly.

In the code below, I used the module @prisma/client as source for type generation, but for some reason the API still works either I declare sources or not. I'm not sure I understood how this property works and how to use it...

I'd be grateful if someone could clarify it for me!

const schema = makeSchema({
  types: [Query, Mutation, Post, User, Review],
  plugins: [nexusPrisma({ experimentalCRUD: true })],
  outputs: {
    schema: path.join(__dirname, 'schema.graphql'),
    typegen: path.join(__dirname, '../prisma/generated', 'nexus.ts'),
  },
  typegenAutoConfig: {
    sources: [
      {
        source: '@prisma/client',
        alias: 'prisma',
      },
    ],
  },
})
