I am properly linking the javascript files however It says there was an error trying to load the resource and it says Invalid Extension Version Param, I am just trying to get a basic react app to work first then I can work on querying apis and what not.

I figured it out, I needed to remove the leading / from the file names to get it to work.

Just to answer even though you solved, for others

Extensions are uplaoded to a sub folder on the extensions domain of Twitch.

So your HTML/JS/CSS isn’t at the root of the domain that the files exist upon

I wrote about the domain structure here Twitch Extensions: Part 3 – The Architecture of an Extension – Barry Carlyon
