# Minifier

A high-performance minifier that shrinks your code by removing unused code and transforming to a shorter equivalent.

## Features

* [Eliminate dead code.](./minifier/dead-code-elimination)
* [Transforms syntaxes to make the output shorter and repetitive.](./minifier/syntax-normalization)
* [Mangle variable names and selected property names.](./minifier/mangling)
* [Remove whitespace and comments.](./minifier/codegen#whitespace-stripping)
* [Escape non-ASCII characters.](./minifier/codegen#ascii-escaping)

## Assumptions

To allow better optimizations, Oxc minifier makes some assumptions about your code. See [Assumptions document](https://github.com/oxc-project/oxc/blob/main/crates/oxc_minifier/docs/ASSUMPTIONS.md) for more information.

## FAQ

See [FAQ](./minifier/faq) for common questions.

## Installation

### With Rolldown

If you are using [Rolldown][url-rolldown], `oxc-minify` will be used for minification by default. No extra installation is required.

### Node.js

* Use the node binding [oxc-minify][url-oxc-minify-npm].
* Try on [stackblitz](https://stackblitz.com/fork/github/oxc-project/website/tree/main/stackblitz-templates/oxc-minify).

### Rust

Use the umbrella crate [oxc][url-oxc-crate] with the `minifier` feature.

Rust usage example can be found [here](https://github.com/oxc-project/oxc/blob/main/crates/oxc_minifier/examples/minifier.rs).
