Body limit in oak@13+

[andreial]

Before oak@13, we were able to add a limit to body:

ctx.request.body({ type: 'json', limit: maxHttpBodyBytes }).value

which was throwing BadRequest whenever the request body was exceeding that limit.

Is there a way to do this using the new body API?

There are some challenges because of the underlying changes of the way Deno HTTP server works. In other runtimes like Bun, it is controllable at the HTTP server, and there isn't a consistent way to enforce that in the middleware framework. It isn't a bad idea, but there isn't a clear way to implement that is obvious.
