RESTful Event Handler Middleware modifications and typings

[nateiler]

One middleware we often introduce in a multi-tenant api is a transaction middleware which is responsible for extracting various parts of the request (mostly from the authorizer context) and providing a Transaction object to the route(s).

With the introduction of middleware, what is the proposed approach for a middleware needing to modify the request context? In this particular scenario, I would like to attach a transaction property and have the typing available within the route.

In general, it seem like any manipulations that occur within the middleware is unable to update the request context typing

Hi @nateiler, thanks for the question.

You're right, at the moment there's no way to pass state between middleware functions and route handlers, but we're planning on adding an API very soon.

We started having a discussion in this issue (see this comment), but I'm going to create a dedicated issue later today.
