client-zip VS Penumbra

Absolutely! Here’s one I found very useful just the other day, client-zip: https://github.com/Touffy/client-zip#usage

(Three functions rather than one, but it’s one main entrypoint and a couple of minor variants.)

I think this is a really well-designed API, and greatly preferable to a more fine-grained OO approach. It does a lot of work under the hood but keeps it carefully contained so you don’t get a bunch of dependency sprawl.

This is an interesting use case, thanks a lot for sharing. I haven't tested this, but https://github.com/Touffy/client-zip looks interesting and might work in Deno Edge Functions.

you need penumbra if you don't have it yet and use that to install the mod

You can find various body edits on https://www.xivmodarchive.com/ . In order to use them, the easiest way is to use the XIVLauncher (https://github.com/goatcorp/FFXIVQuickLauncher) which enables the addon system. With that, download the addon "Penumbra" to use those edited bodies ingame (https://github.com/xivdev/Penumbra).

Runtime loader (Custom clothes, animation): https://github.com/xivdev/Penumbra (a year old)

You'll need Penumbra, which in itself requires Dalamud ala the FFXIVQuickLauncher tool. You can install FFXIVQuickLauncher via an installer and here's a video for installing Penumbra.

Download that, also download textools https://www.ffxiv-textools.net/ OR penumbra https://github.com/xivdev/Penumbra (this one also needs XIVLauncher) and then import the file you downloaded from nexusmods, and that's it.

Penumbra

Penumbra is a quicklauncher plugin (link) that allows you to non-destructively apply mods.

From what I understand that was fixed a few versions ago. https://github.com/xivdev/Penumbra/releases/tag/0.4.6.7

Should be this one I think.
