When I try to load this file (https://github.com/LocalIdentity/PathOfBuilding/blob/master/Modules/Common.lua) I'm getting this error :

uncaught exception http://localhost:3000/PathOfBuilding/Modules/Common.lua:23: module 'lcurl.safe' not found:
    no field package.preload['lcurl.safe']
    no file './lua/5.3/lcurl/safe.lua'

I followed the Getting started from your website https://fengari.io/, but replaced "/my-script.lua" with the file I linked previously. The error come from require, the script I try to run want to load some external library, how can I handle that? Is there a function to tell fengari that a script tag corresponds to a specific extension? Also, I know nothing about Lua, I just want to run a project written in Lua in a browser extension and your project looks like what I need.

Your script tries to load the lcurl.safe library: you would need to provide this library somehow (or some compatibility layer for it).
