# JavaScript to WebAssembly Compilation Comparison
|
# JavaScript to WebAssembly Compilation: Performance Analysis
|
||||||
|
|
||||||
A comprehensive analysis and comparison of different approaches to compile JavaScript to WebAssembly, with a focus on size optimization and runtime compatibility.
|
## Executive Summary
|
||||||
|
|
||||||
## 🎯 Overview
|
**Optimal choices by use case:**
|
||||||
|
- **Minimal size (< 10KB)**: AssemblyScript - 8.2KB gzipped
|
||||||
|
- **Balance (< 100KB)**: Porffor - 75.1KB gzipped (9.1x larger than smallest)
|
||||||
|
- **Full JS compatibility**: QuickJS - 265.5KB gzipped (32.3x larger, Wasmer/Extism compatible)
|
||||||
|
- **Avoid**: Go+Goja - 3.6MB gzipped (445.7x larger than AssemblyScript)
|
||||||
|
|
||||||
This repository explores 7 different JavaScript-to-WASM compilation approaches:
|
## Size Comparison (Actual Measurements)
|
||||||
|
|
||||||
1. **AssemblyScript** - 12KB gzipped ✨ **Smallest size**
|
*Data location: `results/size-comparison.csv`*
|
||||||
2. **TinyGo (optimized)** - 128KB gzipped ✅ **Good balance**
|
|
||||||
3. **Porffor** - 128KB gzipped (Node.js only)
|
|
||||||
4. **QuickJS (Rust)** - 320KB gzipped ✅ **Recommended for Wasmer**
|
|
||||||
5. **TinyGo Basic** - 384KB gzipped (Browser/Node.js)
|
|
||||||
6. **Go Basic** - 896KB gzipped (Browser/Node.js)
|
|
||||||
7. **Go + Goja** - 4.1MB gzipped (Full JS engine in Go)
|
|
||||||
|
|
||||||
## 🏆 Key Results

## Key Findings
|
||||||
|
|
||||||
|
1. **Size efficiency**: AssemblyScript produces the smallest binaries (8.2KB) but with limited JS compatibility
|
||||||
|
2. **Porffor issues**: Shows promise (75KB) but has compilation failures with invalid branch depths
|
||||||
|
3. **QuickJS sweet spot**: At 265KB provides full JS support with Wasmer/Extism compatibility
|
||||||
|
4. **Go overhead**: Go-based solutions are 100-445x larger than AssemblyScript
|
||||||
|
5. **Compression rates**: Range from 55% (AssemblyScript) to 85% (Porffor)
|
||||||
|
|
||||||
|
## Recommendations
|
||||||
|
|
||||||
|
| Use Case | Recommendation | Size | Rationale |
|
||||||
|
|----------|---------------|------|-----------|
|
||||||
|
| Size-critical | AssemblyScript | 8.2KB | Smallest possible WASM |
|
||||||
|
| General purpose | QuickJS | 265KB | Full JS + Wasmer support |
|
||||||
|
| Node.js only | Porffor* | 75KB | Good size (*if fixed) |
|
||||||
|
| Avoid | Go + Goja | 3.6MB | 445x overhead unjustified |

## 🔬 Research Findings
|
|
||||||
|
|
||||||
### Wasmer v6.1.0-rc.2 Dynamic Linking
|
|
||||||
- Introduces dynamic linking for WASIX/C++ libraries
|
|
||||||
- Does NOT support WASM module import resolution
|
|
||||||
- Javy dynamic builds still require Node.js runtime
|
|
||||||
|
|
||||||
### Size Optimization Techniques
|
|
||||||
- **wasm-opt**: 15-20% size reduction
|
|
||||||
- **Compression**: 60-70% reduction with gzip
|
|
||||||
- **Dead code elimination**: Significant impact on Go builds
|
|
||||||
|
|
||||||
### Runtime Performance
|
|
||||||
- **WASI overhead**: Minimal (~1ms)
|
|
||||||
- **JavaScript engine startup**: 5-10ms
|
|
||||||
- **Execution performance**: Comparable to native JavaScript

## 📌 Recommendations
|
|
||||||
|
|
||||||
- **For smallest size**: Use **AssemblyScript** (12KB) - ideal for simple transformations
|
|
||||||
- **For balance of size and features**: Use **TinyGo optimized** (128KB) or **Porffor** (128KB)
|
|
||||||
- **For full JavaScript support in Wasmer**: Use **QuickJS** (320KB) - complete JS engine in WASM
|
|
||||||
- **For existing Go codebases**: Use **TinyGo** (128-384KB) depending on optimization needs
|
|
||||||
- **For complex JavaScript transformations**: Use **Go + Goja** (4.1MB) if size isn't critical

```
|
||||||
|
|
||||||
|
## Methodology
|
||||||
|
|
||||||
|
### What We Measure
|
||||||
|
|
||||||
|
For each runtime/language combination, we measure:
|
||||||
|
|
||||||
|
1. **Dependency Download Size**: Total bytes fetched from package registries
|
||||||
|
2. **Installed Footprint**: Uncompressed size on disk after installation
|
||||||
|
3. **Deployed Artifact Size**: Size increase of deployable artifacts (binaries, JARs, bundles)
|
||||||
|
4. **Native Libraries**: Count and size of native libraries included
|
||||||
|
5. **Lazy Downloads**: Any runtime downloads on first execution
|
||||||
|
|
||||||
|
### Measurement Approach
|
||||||
|
|
||||||
|
#### Python
|
||||||
|
- **Baseline**: Empty venv with minimal script
|
||||||
|
- **With Runtime**: venv with Wasmer/Extism SDK installed
|
||||||
|
- **Metrics**: venv size delta, pip download size, native .so/.dylib files
|
||||||
|
|
||||||
|
#### TypeScript/Node.js
|
||||||
|
- **Baseline**: Empty npm project
|
||||||
|
- **With Runtime**: Project with runtime SDK dependencies
|
||||||
|
- **Metrics**: node_modules size delta, npm pack size, native bindings
|
||||||
|
|
||||||
|
#### Go
|
||||||
|
- **Baseline**: Minimal Go binary
|
||||||
|
- **With Runtime**: Binary with runtime SDK statically linked
|
||||||
|
- **Metrics**: Binary size delta, module cache size
|
||||||
|
|
||||||
|
### Test Modules
|
||||||
|
|
||||||
|
- **add.wasm**: Minimal 41-byte module exporting `add(i32, i32) -> i32`
|
||||||
|
- **wasi_hello.wasm**: Simple WASI module returning constant value
|
||||||
|
- **extism_echo.wasm**: Extism plugin with echo functionality (when built)
|
||||||
|
|
||||||
|
## Running Measurements
|
||||||
|
|
||||||
|
### Quick Start
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Measure all implementations
|
||||||
|
mise run measure:runtimes:all
|
||||||
|
|
||||||
|
# Measure specific runtime/language
|
||||||
|
mise run measure:wasmer:python
|
||||||
|
mise run measure:wasmer:typescript
|
||||||
|
mise run measure:wasmer:go
|
||||||
|
mise run measure:extism:python
|
||||||
|
```
|
||||||
|
|
||||||
|
### Manual Execution
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Build test modules
|
||||||
|
cd runtimes/test-modules
|
||||||
|
python3 create_test_modules.py
|
||||||
|
|
||||||
|
# Run individual measurement
|
||||||
|
cd runtimes/wasmer/python
|
||||||
|
python3 measure.py
|
||||||
|
|
||||||
|
# Run all measurements
|
||||||
|
cd runtimes
|
||||||
|
./measure_all.sh
|
||||||
|
```
|
||||||
|
|
||||||
|
## Results Format
|
||||||
|
|
||||||
|
Each measurement outputs JSON with:
|
||||||

|
||||||
|
|
||||||
|
### Footnotes
|
||||||
|
|
||||||
|
¹ **Wasmer Python Package Structure**: The wasmer 1.1.0 package on PyPI is the core API package only. To actually compile and run WebAssembly, you need to install a compiler engine separately:
|
||||||
|
- `pip install wasmer-compiler-cranelift==1.1.0` (recommended for development)
|
||||||
|
- `pip install wasmer-compiler-llvm==1.1.0` (recommended for production)
|
||||||
|
- `pip install wasmer-compiler-singlepass==1.1.0` (fastest compilation)
|
||||||
|
|
||||||
|
Our measurement only included the core package. With cranelift compiler, the total download would be significantly larger.
|
||||||
|
|
||||||
|
² **Wasmer Go Dynamic Linking**: The Go binary dynamically links to `libwasmer.dylib` which must be installed separately or bundled with the application. The binary size increase (159KB) doesn't include the ~40MB libwasmer library. For distribution, you need either:
|
||||||
|
- System-wide Wasmer installation
|
||||||
|
- Bundle libwasmer.dylib with your application
|
||||||
|
- Use CGO_ENABLED=0 for static linking (if supported)
|
||||||
|
|
||||||
|
### Analysis & Recommendations
|
||||||
|
|
||||||
|
#### Key Takeaways
|
||||||
|
|
||||||
|
1. **Go requires external dependencies**: Despite small binary size increase (159KB), it needs libwasmer.dylib (~40MB) at runtime due to dynamic linking.
|
||||||
|
|
||||||
|
2. **TypeScript/Node.js is self-contained**: 12.8MB for @wasmer/sdk includes everything needed, making deployment simpler.
|
||||||
|
|
||||||
|
3. **Python Wasmer is modular**: Requires separate compiler package installation. Total size with compiler would be much larger than our 3.9KB measurement.
|
||||||
|
|
||||||
|
4. **Extism is all-inclusive**: At 21.9MB for Python, it bundles everything needed including native libraries.
|
||||||
|
|
||||||
|
#### Recommendations by Use Case
|
||||||
|
|
||||||
|
- **Self-contained deployment**: Use TypeScript with @wasmer/sdk (12.8MB all-inclusive)
|
||||||
|
- **Minimal binary size**: Use Go, but plan for libwasmer distribution
|
||||||
|
- **Python applications**: Install both wasmer and a compiler package, or use wasmtime
|
||||||
|
- **Plugin systems**: Extism provides the most complete out-of-box experience
|
||||||
|
|
||||||
|
### Platform Considerations
|
||||||
|
|
||||||
|
- **macOS ARM64**: Some SDKs may not have pre-built wheels/binaries
|
||||||
|
- **Python 3.13**: Newer Python versions may lack wheel support
|
||||||
|
- **Native Libraries**: Dynamic vs static linking varies by language
|
||||||
|
- **Lazy Downloads**: Some SDKs download native components on first use
|
||||||
|
|
||||||
|
## Adding New Languages
|
||||||
|
|
||||||
|
To add Ruby or Java support:
|
||||||
|
|
||||||
|
1. Create directory: `runtimes/{runtime}/{language}/`
|
||||||
|
2. Add implementation files:
|
||||||
|
- `main.{ext}`: Runtime loader/executor
|
||||||
|
- `baseline.{ext}`: Minimal app without runtime
|
||||||
|
- `measure.{sh|py|js}`: Measurement script
|
||||||
|
3. Update `measure_all.sh` to include new language
|
||||||
|
4. Add mise task in `.mise.toml`
|
||||||
|
|
||||||
|
## Known Issues
|
||||||
|
|
||||||
|
1. **Wasmer Python on ARM64**: Limited wheel availability
|
||||||
|
2. **Extism Plugin Format**: Requires Extism-specific WASM format
|
||||||
|
3. **Version Compatibility**: Some SDK versions may not support latest language versions
|
||||||
|
|
||||||
|
## Future Improvements
|
||||||
|
|
||||||
|
- [ ] Add Ruby implementations
|
||||||
|
- [ ] Add Java implementations
|
||||||
|
- [ ] Create Docker containers for reproducible Linux measurements
|
||||||
|
- [ ] Add performance benchmarks (instantiation time, call overhead)
|
||||||
|
- [ ] Measure memory footprint at runtime
|
||||||
|
- [ ] Test with real-world WASM modules
|
||||||
|
- [ ] Add CI/CD automation for measurements

# Test WASM Modules
|
||||||
|
|
||||||
|
These are minimal WASM modules used for testing runtime overhead.
|
||||||
|
|
||||||
|
## add.wasm
|
||||||
|
- **Size**: 41 bytes
|
||||||
|
- **SHA256**: f61fd62f57c41269c3c23f360eeaf1090b1db9c38651106674d48bc65dba88ba
|
||||||
|
- **Exports**: add(i32, i32) -> i32
|
||||||
|
- **Description**: Simple addition function for basic runtime testing
|
||||||
|
- **Source**: Hand-crafted binary (equivalent to WAT: (module (func $add (param i32 i32) (result i32) (i32.add (local.get 0) (local.get 1))) (export "add" (func $add))))
|
||||||
|
|
||||||
|
## wasi_hello.wasm
|
||||||
|
- **Size**: 38 bytes
|
||||||
|
- **SHA256**: 53bd3da2fb75bcafb0677938f211ce6c85da8b6c1b6607b239786373b767e155
|
||||||
|
- **Exports**: hello() -> i32
|
||||||
|
- **Description**: Minimal WASI module that returns 42
|
||||||
|
- **Source**: Hand-crafted binary (returns constant value, no actual WASI imports)
|
||||||
|
|
||||||
|
## extism_echo.wasm
|
||||||
|
- **Note**: Requires Extism PDK to build. Will be created when needed for Extism-specific tests.
