Access to Original Request on handlers.

Hi. Thanks for this awesome tool. It is making my life easier. 😀

Is your feature request related to a problem? Please describe.

Given the request handler below:

rest.post('/path', (req, res, ctx) => {
    // ...
}),

The req object is slightly different in the Browser and Node environments.

In Node:

• If the content-type is json it parses it and makes the data available on req.body.
• Otherwise it pass the original Body from the request. With this we have the chance to receive other object responses like FormData.

In the Browser:

• msw parses the body as text before pass it to the handler.

Describe the solution you’d like

Have a clone of the original request in the req object. This way the handler has access to the Body mixin methods to read the data in other formats: FormData, Blob, ArrayBuffer, etc.

Describe alternatives you’ve considered

To mock a multipart/form-data request I had to create a custom parser. It works just fine but if we have this feature available for free I guess it makes sense to passed it to the handler.

Does this makes sense? I can submit a PR with the suggested changes.

Hi @marcosvega91 and @kettanaito,

First, thanks for the very fast response. I was not completely aware of the MessageChannel (I just read the WebWorker docs). Now knowing that it was not an easy win like I initially thought, I agree with @kettanaito. Maybe this is a customization to my use case: I am saving some data in-memory to simulate the interactions when running on the browser for fast prototyping.

Yes, this is what I am currently doing. 😀
