LEARNING OBJECTIVES ⌵
- Understand AST (Abstract Syntax Tree) transformation and minification mechanics.
- Strip comments, whitespace, and collapse boolean attributes in production HTML.
- Configure Tree-Shaking and Dead Code Elimination in modern bundlers.
- Preserve source maps (
.map) securely for production error tracking without exposing client code.

📖 The Minification Pipeline
Raw HTML Source (48 KB) ===> Tokenizer ===> Tree-Shaking & Minifier ===> Output (18 KB)
- Strip HTML Comments (<!-- ... -->)
- Collapse Redundant Whitespace
- Remove Default Attribute Values (type="text", method="get")
- Shorten Class Names & Mangle Variables
📌 Key Takeaways
- Minification strips unneeded characters, comments, and whitespace while preserving 100% semantic functionality.
- Keep source maps hosted on private error tracking servers (e.g. Sentry) rather than public CDN roots.
