## What it is
A highly configurable, well-tested JavaScript-based HTML minifier with Node.js and CLI support, capable of also minifying inline CSS and JavaScript. It is now deprecated and unmaintained; users should switch to HTML Minifier Next.

## Use cases
- minify html files for production
- compress html in a node build pipeline
- reduce page weight by stripping comments and whitespace
- minify inline css and js inside html
- run html minification from the command line

## When to choose
- you need a battle-tested, highly configurable HTML minifier for Node.js or CLI
- you want to minify embedded CSS and JS along with HTML
- you're maintaining a legacy build pipeline already using html-minifier

## When to avoid
- starting a new project - use HTML Minifier Next instead
- you need security fixes or ongoing maintenance
- you need minification of non-HTML assets only

## Facets
- artifact type: library
- maturity: abandoned
- function: parser, compression, cli, developer-tools
- domain: web-development, frontend, developer-tools, performance
- platform: cli, cross-platform
- tags: html-minifier, minification, deprecated, build-pipeline, nodejs
