## What it is
CommentCoreLibrary is a JavaScript/TypeScript engine for rendering streaming danmaku (bullet) comments over timed HTML5 video or audio. It provides the core controller for displaying, animating, and filtering timed comment overlays in web-based players.

## Use cases
- add danmaku bullet comments to an html5 video player
- render scrolling live comments over video streams
- build a video player with niconico-style comment overlays
- stream timed comments on top of audio or video playback
- filter and style danmaku comments in the browser
- integrate comment streaming into a custom web player

## When to choose
- you need danmaku/bullet-comment overlays for HTML5 media in the browser
- you want a mature, MIT-licensed core engine to extend in your own player
- you need advanced danmaku features like CSS-styled comments, filters, and scripting

## When to avoid
- you need a full video player UI rather than just a comment engine
- your project is not web/JavaScript based and you cannot adapt the modules
- you need server-side comment storage or delivery - this only handles client-side rendering

## Facets
- artifact type: library
- maturity: maintenance
- function: animation, ui-components, frontend-framework
- domain: web-development, frontend, media, entertainment
- platform: browser, cross-platform
- tags: danmaku, live-comments, video-overlay, html5-video, bullet-comments, typescript, nodejs
