is ther any way to add our own mutations to serving graphql server

[ethdev279]

When I run graphclient serve-dev, I can see graphql server wrapping existing subgraph api. I'm wondering if we can extend our graph client server with additional custom mutations/queries?

Yes! You can extend the schema with additionalTypeDefs and additionalResolvers;

Exactly what I needed. Thanks much!

getting this now: Schema is not configured to execute mutation operation. can you pls help me? @ardatan

[ardatan]

Could you create a reproduction on CodeSandbox or StackBlitz? So we can move better.

I think It is missing in the docs. You have add this on top of additionalTypedefs ;

extend schema {
   mutation: Mutation
}

I created this PR to update docs.
