A module that listens on a port and keeps track of each HTTP request it receives, and makes them available via a .nextResponse() method

For use especially with creating tests for APIs that utilise a HTTP callback as part of their response mechanism (for when there is asynchronous actions on the server end, like a blockchain transaction being minded for example)

const CallbackListener = require('callback-listener-next-response')

const listener = new CallbackListener( port )

async () => {
	const callbackResponse = await listener.nextResponse()
}();

The properties of the object returned by nextResponse() include :

• request.body
• request.method

(See the Koa request object for more details)

This module could do with some tidying up, for now you can see how it works by doing the following :

node test/test.js

And in another tab do :

curl http://localhost:5123 -X POST --header "hello: API callback listener world" --data "It works"
