The root problem is the JS file we’re generating our .zipline
from is aggressively minified, and that deprives QuickJS of line number information.
I was able to fix by creating webpack.config.d/treehouseWebpackConfig.js
in the module directory with these contents:
config.optimization = config.optimization || {};
const TerserPlugin = require("terser-webpack-plugin");
config.optimization.minimizer = [
new TerserPlugin({
terserOptions: {
compress: {
sequences: false,
},
mangle: false,
format: {
beautify: true,
braces: true,
}
},
}),
];
from zipline.
The costs of good debug data are too damn high!
.zipline size gzipped size
A NO DEBUG DATA 2,856,719 941,474
B MANGLE CLASS + FUNCTION NAMES 3,400,044 (+19%) 1,193,241 (+27%)
C OMIT INSTRUCTION LINE NUMBERS 3,690,174 (+29%) 1,218,497 (+29%)
D TRUNCATE FILE PATH 3,642,791 (+28%) 1,338,461 (+42%)
E (B + C) 3,218,986 (+13%) 1,064,318 (+13%)
F FULL DEBUG DATA 3,871,128 (+35%) 1,346,230 (+42%)
Before closing this we should zipline { }
Gradle plugin options for these:
- Stripping the pc2line table
- Mangling class + function names
from zipline.
