haproxy-auth-request VS luabundler

I've followed the HAProxy example for Lua-based auth server (https://bl.duesterhus.eu/20180119/).

A lot of the more advanced HAproxy configs for SSO (think Authelia for example) require the use of Lua scripts which would be fine, but the scripts themselves need to reference OTHER scripts. For example haproxy-auth-request requires the use of haproxy-lua-http which needs to reference a JSON library such as json.lua. You usually will see statement such as local http = require("haproxy-lua-http") which indicates our script very explicitly is looking for that other script.

I wonder if a bundler would help? For example: https://github.com/Benjamin-Dobell/luabundler. I haven't tried it but in theory you should be able to point it at your home configuration and get a single file that includes it all.

So short of trying to fix the code, of which most of us are not equipped to do, what can we do? Well, there is a really fun little tool called luabundler. This tool will analyze the Lua file you feed it, figure out all the dependency Lua scripts based on the require statements, and then wrap them all up in one self-contained Lua script! All we need is Node, the bundler, and the individual scripts.

There's also a stand-alone CLI https://github.com/Benjamin-Dobell/luabundler
