# Oxc Minifier
Next-generation JavaScript/TypeScript minifier achieving best-in-class compression.
## Inspiration
- **Closure Compiler**: Advanced size optimizations
- **Terser/UglifyJS**: Comprehensive battle-tested transforms
- **esbuild**: Efficient algorithms and architecture
- **SWC**: Modern Rust performance
## Key Features
- Maximum compression through exhaustive optimizations
- 100% correctness with comprehensive testing
- Fixed-point iteration for optimal size
- Arena allocation for performance
## Current Performance
See [`tasks/minsize`](../../tasks/minsize) for compression benchmarks.
- Matching/beating esbuild on many libraries
- Full test262, Babel, TypeScript conformance
## Usage
```rust
use oxc_minifier::{Minifier, MinifierOptions};
let options = MinifierOptions::default();
let minifier = Minifier::new(options);
let result = minifier.minify(&mut program);
```
## Testing Infrastructure
- `just minsize` - Track compression benchmarks
- `cargo coverage` - Conformance tests (test262, Babel, TypeScript)
- `tasks/e2e` - Real-world E2E testing
## Development
- `just test` - Run all tests
- `cargo run -p oxc_minifier --example minifier` - Try the minifier
## Key Dependencies
- [`oxc_ecmascript`](../oxc_ecmascript) - ECMAScript operations and constant evaluation
- [`oxc_semantic`](../oxc_semantic) - Scope and symbol analysis
- [`oxc_mangler`](../oxc_mangler) - Variable renaming
