best practice for custom http responses

[TomerSalton]

Hey,

I want to change the HTTP response (both errors and message) that is returned by the server.
Two examples:

1. If a user tries to send a PUT request in order to create an item, I want to return him a "ERROR 501 Not Implemented" response.
2. If a user sends a POST request that requires a lot of processing power, I want to return HTTP 202 (Created).

Would you be able to provide me the best practice of implementing those HTTP responses customizations?

Thanks alot for your help,
Tomer.

@TomerSalton, do you mean to change the HTTP response outside the controller?
If yes, could you please take a look at the discussion thread in #1867? especially this comment and this comment. Thanks.

Is there any plan to do first-class support on custom HTTP response (not just error-handling)?

I've followed the solution on StackOverflow. However, this meant that the repository now expects an @loopback/rest.Response, on which how to mock is not documented.

Otherwise, is there a way to create controller unit tests?

See an example at https://github.com/strongloop/loopback-next/blob/master/packages/rest/src/__tests__/unit/writer.unit.ts. stubExpressContext is the helper.
