Subscription - ApolloServer context & Graphql-ws context

[RemyMachado]

I'm currently setting the apollo server context using an async callback:

const server = new ApolloServer({
 ...
 context: ({ req }) => {
        ... // returning Promise<context>
        }
}

Now I'm duplicating the code to give a context to the graphql-ws implementation:

const webSocketServerCleanup = useWebSocketServer(
        {
            schema: schemasAndResolvers,
            context: {
                ...
            },
        },
        wsServer
    )

I didn't succeed to set it up the same way since the signatures are different (how to retrieve the req obj for WS?).
ApolloServer context:
context?: Context | ContextFunction<ContextFunctionParams>;

Graphql-ws context:
context?: GraphQLExecutionContextValue | ((ctx: Context<P, E>, message: SubscribeMessage, args: ExecutionArgs) => Promise<GraphQLExecutionContextValue> | GraphQLExecutionContextValue);

What's the right way to have the same context in both servers?

Any help would be greatly appreciated.

I found that I can use ctx.connectionParams.Authorization to retrieve the bearerToken, and for the dataSources I may call the creatorFn, but I'm not sure it's the best way. Isn't there a way to synchronize them, without creating them twice?

You do have to write different code because the data structures are actually different. One represents parsing an HTTP request (based on your favorite web framework such as Request); the other represents parsing the beginning of a Websocket stream.

Thank you for your answer, it makes sense.

I'll leave the discussion unanswered, in case I or someone come up with a solid implementation. I might create an adapter to reuse most of the logic and create an example.
