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
Real-library tests
You can use vscode to see diffs. Select a file from tests/projects/output and select the corresponding file from tests/projects/refs. Then you can right click to see an option to open diff.
Splitting a library test
Extracting only subset from a library test makes development much easier.
Split status:
- angular-1.2.5
- backbone-1.1.0
- jquery-1.9.1
- jquery.mobile-1.4.2
- mootools-1.4.5
- underscore-1.5.2
- yui-3.12.0
Tests from terser
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
