Introducing The Jres Specification

December 10, 2019

I have been making JSON/REST APIs for a while now, and have always been annoyed with the lack of opinionated structures of JSON/REST API responses. There are a few specs out there, including Jsend (which this specification was inspired from) but lacked in some spaces for me.

Most importantly:

  • Too much useless data being added to the response.
  • Lack of opinionated structure for input field validation errors originating from the UI.
  • Lack of focus on how the UI consumes this data in a modern web application.

The Jres Specification hopes to fix some of these issues. Jres is a specification on how to format JSON RESTful APi responses.

The spec itself is really quite simple, with only a few keys being required in the return JSON object. If you care to read more about it, you can check out the dedicated website below:
