WASM regex size demo

This demo shows how regex crate contributes to WASM binary size.

How-to

1. Go to Cargo.toml and select regex features
2. Build: wasm-pack build
3. Check out pkg/regex_wasm_demo_bg.wasm

Results

For me the results with regex version 1.6.0 were as follows:

• Baseline (no regex): 1 KiB
• Limited Unicode support, no optimizations: 214 KiB
• Limited Unicode support, full optimizations: 338 KiB
• Full Unicode support, no optimizations: 500 KiB
• Full Unicode support, full optimizations (default features): 623 KiB
