Minifier

EcmaScript minifier for the swc project. This is basically a port of terser.

Note

Currently name mangler is very simple. To focus on creating a MVP, I (kdy1) will use simple logic for name mangler and implement the content-aware name mangler after publishing first non-beta version.

Testing

Tests ported from terser has

  • input.js
  • config.json
  • mangle.json (if name mangling is enabled)
  • output.js (if exists and can be modified if our one is better or due to lack of frequency-aware base54)
  • output.terser.js (if exists)

Copying tests

Replace the content of terser/test/compress.js with it of scripts/compress.js and run npm run test:compress
