Enabling minification reduces bundle size significantly while maintaining full
debugging capability through source maps.
Size reductions (what consumers download over network):
📦 STANDARD BUILD
ES Module:
Raw: 2,299 KB → 1,714 KB (25.4% reduction)
Gzipped: 486 KB → 423 KB (12.9% reduction)
UMD Module:
Raw: 2,425 KB → 1,361 KB (43.8% reduction)
Gzipped: 492 KB → 384 KB (21.9% reduction)
📦 BUNDLED BUILD (with styled-components)
ES Module:
Raw: 2,361 KB → 1,767 KB (25.1% reduction)
Gzipped: 506 KB → 441 KB (12.7% reduction)
UMD Module:
Raw: 2,487 KB → 1,400 KB (43.7% reduction)
Gzipped: 511 KB → 400 KB (21.8% reduction)
Average: 34.5% reduction (raw), 17.3% reduction (gzipped)
Background:
- minify: false was added in March 2024 (PR #371) to aid debugging
- sourcemap: true was added in July 2024 (PR #644) to improve stack traces
- With source maps enabled, minification no longer affects debugging experience
Benefits:
- Smaller bundle size for faster downloads and better CDN caching
- Source maps still provide full TypeScript source-level debugging
- Follows industry standard (React, Material-UI, etc. all ship minified)
- Browsers load source maps on-demand only when devtools are open
Consumer Impact:
- Consumers download 60-111 KB less per bundle (gzipped)
- No loss of debugging capability - stack traces show original TypeScript
- DevTools display original source code, not minified code
