wtf is douyulive-danmu-merge?

This project is a web-based helper for watching live chat comments, called danmu, from Douyu, a Chinese live streaming platform. It is built to deploy as a single file on Cloudflare Workers or Cloudflare Pages, so setting it up does not require running a traditional server. Once deployed, it gives a viewer a webpage that connects directly to a Douyu live room and shows the chat comments in a cleaner, more readable format, along with a display mode meant to be used as an overlay in OBS for people who are streaming. The browser connects straight to Douyu's own chat server over a WebSocket connection, so the Cloudflare Worker itself only serves the static webpage and does not relay or store any chat traffic, keeping it cheap to run. A key feature is automatic merging of repeated spam-style comments: when many viewers post the same or similar text in a short time window, the tool groups them into a single combined entry with a badge showing how popular that comment is, and comments repeated more than ten times get pinned to the top of the screen so they are not missed. The tool also includes optional text to speech playback of comments and gifts, a way to look up a commenter's past messages by clicking their name, and adjustable settings like background transparency, font size, and how many messages to keep on screen at once, which helps keep things smooth on slower devices. Configuration includes toggles for showing normal comments, gift and subscription events, and viewer join notifications, plus a filter for automated bot comments that carry no user identity information. A room can be opened automatically by adding its room number to the page's web address, which is convenient for setting up a fixed OBS browser source. The chat parsing logic builds on an earlier open source project called douyuEx. It is released under the MIT license, with a note asking that it only be used for normal viewing, chat analysis, and research rather than spam or actions that violate Douyu's own platform rules.
