4chan XT is a script that adds various features to anonymous imageboards. It was originally developed for 4chan but has no affiliation with it.

Originally forked from 4chan X for this PR, this fork started getting some features on its own. See the changelog.

New features include:

Fetching the thread from an external archive and inserting deleted posts
Basic audio posts support
Automatically converting unsupported image files to PNG
Automatically JPG'ing image files above the size limit
Having both relative time and a timestamp on a post at the same time
Counting poster ID's as a replacement of the deleted IP counter
Hiding all posts from a poster ID in a thread
A manifest v3 version for chromium browsers dropping support for v2
A button to un-randomize a filename in the quick reply

The 4chan XT project is a migration of 4chan X from coffeescript to TypeScript/JavaScript. It is named XT both as a continuation of eXTended, and a T for TypeScript. The goals of this project is to first get a working bundle from js/ts files, and then gradually convert js files to ts and add types as needed.
