Bundle Size

Keep WASM bundles small for fast loading.

Target

<500KB gzipped for production

Size Breakdown

Optimization Steps

1. Release Build

cargo build --target wasm32-unknown-unknown --release

2. LTO (Link-Time Optimization)

[profile.release]
lto = true
codegen-units = 1

3. wasm-opt

wasm-opt -O3 -o optimized.wasm output.wasm

4. Compression

gzip -9 optimized.wasm
# Or brotli for better compression
brotli -9 optimized.wasm

Measuring

# Raw size
ls -lh output.wasm

# Compressed size
gzip -c output.wasm | wc -c

Verified Test

#[test]
fn test_bundle_size_concerns() {
    // Verify we're thinking about size
    use std::mem::size_of;

    // Small types = small bundle
    assert!(size_of::<presentar_core::Size>() <= 8);
    assert!(size_of::<presentar_core::Point>() <= 8);
