Invalid schema code generated

[tobimori]

When generating a TypeScript schema (without frameworks, without subscribes) for https://api.expo.dev/graphql, the generated code contains 3 instances of:

  8839 |     limit: ScalarsEnums["Int"];
  8840 |     offset: ScalarsEnums["Int"];
> 8841 |   }) => Array<[Update!]>;
       |                      ^

Which is not valid TypeScript syntax.

From my past experiences, this is usually due to an invalid schema of double arrays.

For example:

type Query {
  foo: [[String]] # This is invalid schema definition
  bar: [Bar] # Instead you have to wrap the inner value with an object
}

type Bar {
  baz: String
}

Would you mind sharing your schema here?

You can fetch it from https://api.expo.dev/graphql - This is a third-party API without an official API client and I don't really know much abt GraphQL, sorry for that.

With a quick search, it seems that their introspection query requires an OAuth token that is only acquirable via expo-auth-session.

Assuming it's a public API without vendor specific information, you may attach your schema.generated.ts here; otherwise I'll take some time to write a custom script for their oauth this weekend.

Here's the generated schema - https://gist.github.com/tobimori/d5bfb0bd310b660f25a5e1b8d2335b81

You can generate an Bearer Token via the Expo interface, no need for a complicated Auth setup.

Confirming that Expo contains return type [[Update!]!]! in a few places, servers usually avoid this for backward compatibility. I'll see if we can support that in GQty.
