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
