Hi all, I'm looking to see if anyone has already done the work to hook up ariande with chalice? Searching didn't find anything at this stage. I could just go through the 'other technologies' section to add what I need, but I was hoping someone else had already done it.

Response headers

What if I need to add some headers to HTTP response? In my case it is Access-Control-Allow-Origin to disable CORS protection, but we can also consider other cases when non-standard HTTP Response headers are required. I overrode GraphQL.graphql_http_server method, and it works.…

Check request headers once, potentially return graphql error response

For each incoming request, I need to look at its headers and potentially return a typical error response: It seems simple, but every solution I could come up with has some issues: • using an ariadne middleware - this allows me to return the error response easily, but the…

Dynamic introspection

I'm trying to implement dynamic introspection like in tartiflette, but I can't find a way to exclude fields during introspection using directives. The general idea looks like this: User should not see helloAdmin field in the schema obtained from the introspection, but Admin…
