The one of the most important features - I see thats not mentioned by the author of the post here - even though it should be super highlighted - Voiden is the first client where the entire api request is deconstructed into reusable blocks.
Headers, Query Params, Path Params, Body (JSON, Form params etc)..
and reuse them in different apis to have ALL common elements done in one file and then change them once and it will all get updated in all the other docs (just like in code - when we add a extra logic to an imported method). thats super super convenient and saves so much time compared to all the other tools out there - where you mainly duplicate stuff or just use environment variables to substitute.
OH and the pre and post request scripts - with the support for different languages like JS, python etc .. its amazing.. first API client i use where you can write pre and post api requests in a different language than JS (as a non JS developer this is huge)!
super nice! Not something I can attempt but its great to see how you did it!
