I have build an application but the framework, lihaoyi autowire (minor detail), hides its auto generated and auto maintained path structure and message structure. It is fantastic but the drawback, is it's not visible in the code.
How can I found out the path of the url and the JSON involved? Using the Chrome browser? Other tools to intercept the traffic? Finally I have to use it for to mimic and test it with using e.g. an Advanced REST client as Postman?
An live example, just an example, of this way of programming can be found here.
By coincidence I found out that the url with path for this example "https://hands-on-scala-js.herokuapp.com/ajax/list" is. And I have to post path = "../" header. Tested with Postman.
