# Benchmark JavaScript Minifiers

Compare performance of terser, esbuild and swc as minifiers

## Sample Code

antd + lodash + react + react-dom + three.js

## Integrations

Use webpack + terser-webpack-plugin, which support terser, swc and esbuild minifier.

## Output Standard

- Bundled into one JS file with webpack

- IIFE format output

- Minified without source maps
