Learn TINYGO-WASM with Real Code Examples

Go code compiled by TinyGo frontend

LLVM backend optimizes output

Generates Wasm32 binaries (browser/WASI)

Optional WASI shims for system I/O

Interacts with JS/host via Wasm imports/exports

Go -> TinyGo frontend -> LLVM backend -> Wasm binary

Imports/exports bridge with JS or WASI runtime

Memory is linear Wasm memory space

Host functions provided via imports

Garbage collection with minimal overhead

Wasm-first Go microservices

Browser interop via syscall/js

WASI CLI tools

Edge plugins for serverless

IoT processing modules

Browser+TinyGo WebAssembly apps

Fermyon Spin Wasm microservices

IoT edge devices with TinyGo runtimes

WasmCloud actors written with TinyGo

Plugin systems embedding Wasm modules

Compile Go to extremely small binaries

Support WebAssembly and embedded systems

Maintain Go syntax and developer experience

Optimize for low memory environments

Remain predictable, portable, and safe

TinyGo Wasm scales well in serverless/runtime platforms

Edge deployments allow horizontal scaling

Smaller binaries reduce cold start time

Stateless Wasm modules scale automatically

WASI host runtimes can parallelize workloads

Rewrite performance-critical Go code in TinyGo

Test unsupported stdlib components

Replace heavy reflection-based patterns

Use syscall/js or WASI APIs

Optimize final module with wasm-opt
