schema first from multiple files

[zivfuture]

I tried to split graqhql language code in multiple files like this:

a.graphql:
type Query{
hello: String!
}

b.graphql:
type Query{
hi: String!
}

and typed code like this in gateway, but i get an error
" HotChocolate.SchemaException:“The name Query was already registered by another type. - Type: Query":

services.AddGraphQL(sp => SchemaBuilder.New()
.AddDocumentFromFile("a.graphql")
.AddDocumentFromFile("b.graphql")
.BindComplexType()
.Create());

anyone can help ?

If you define the same type in multiple files, you have to add extend before the type definition in the b.graphql file.

a.graphql:

type Query{
  hello: String!
}

b.graphql:

extend type Query{
  hi: String!
}

Thanks for reply.
I do as you said and get a new error:
{
"errors": [
{
"message": "The field hi does not exist on the type Query.",
"locations": [
{
"line": 7,
"column": 5
}
]
}
]
}

I think you have another issue.

This following code works:

class Program
    {
        static void Main(string[] args)
        {
            var sb = SchemaBuilder.New().AddDocumentFromFile("a.graphql")
            .AddDocumentFromFile("b.graphql")
            .AddResolver("Query", "hi", "Earth")
            .AddResolver("Query", "hello", "World")
            .Create();

            var r = sb.MakeExecutable().Execute("{ hi\nhello\n }");
            Console.WriteLine(r.ToJson());
        }
    }

Result:

{
  "data": {
    "hi": "Earth",
    "hello": "World"
  }
}

Can you please share more code or create a github repo with your code?

We haven’t support for extend on sdl first yet. There is however a big update coming to sdl first. We will soon start discussing sdl first in v11

Closing this issue since splitting types in sdl first is not supported in 10

Is it supported for v11?
