Learn TINYGO-WASM with Real Code Examples
Updated Nov 25, 2025
Performance Notes
TinyGo Wasm binaries are extremely small
Wasm runtime executes at near-native speed
Manual memory management improves performance
Use wasm-opt for extra speed/size gains
Avoid heavy reflection or dynamic features
Security Notes
Wasm sandbox ensures memory isolation
No direct access to OS syscalls unless WASI allows
Safe for untrusted plugin execution
Predictable memory model prevents many vulnerabilities
Binary size reduction reduces attack surface
Monitoring Analytics
Use host runtime profiling
Track Wasm memory usage
Benchmark with wasm-time tools
Browser devtools for Wasm inspection
Manual GC observation via logs
Code Quality
Use Go best practices
Avoid large interfaces/reflection
Keep data structures simple
Benchmark Wasm functions
Document JS bindings thoroughly
