Great news guy we have extension support for the Twitch Desktop app! 🎉 Thanks to Brian Allred which contributed his code that adds the ability to load unpacked extensions and the dependencies. Right now this is just a start to the support and is currently a bit clunky and not standardised. If you are interested to see the full merge request here

As you can see I am using the FrankerFaceZ extension on the new twich app.

Currently to install the extension you will either need the unpacked extension or the script js file. These instructions are on the official Twitch Gitlab Repo as well in case you need to refer back to them.

Extensions / User Scripts

Load unpacked Chrome extensions or User Scripts from your application data directory and you will have to currently to manually update them yourself.

Windows:

• %APPDATA%\Twitch\Extensions
• %APPDATA%\Twitch\Scripts

Linux

• $XDG_CONFIG_HOME/Twitch/Extensions or ~/.config/Twitch/Extensions
• $XDG_CONFIG_HOME/Twitch/Scripts or ~/.config/Twitch/Scripts

macOS

• ~/Library/Application/Twitch/Extensions
• ~/Library/Application/Twitch/Scripts

A idea I want to eventually do to fix this is add a system that allows to see available extensions that you can enable/disable on a click of a button and auto update from source but that will be something I will have to work with someone to figure out how to implement later in the future.

You can download the latest version from the release page here or if you are using a Arch based system you will already have a notification on a package update.
