Example: uTLS.wasm

This example shows how to build a fully functional TLS client with TinyGo from uTLS.

Build

Go 1.20/1.21 is required to build this example until TinyGo supports Go 1.22.

tinygo build -o utls.wasm -target=wasi -scheduler=asyncify -gc=conservative -tags=purego .

Debug

tinygo build -o utls.wasm -target=wasi -scheduler=asyncify -gc=conservative -tags=purego .

Release

tinygo build -o utls.wasm -target=wasi -no-debug -scheduler=asyncify -gc=conservative -tags=purego .

Dependencies

The utls imported must be from the wasm branch of uTLS. You may use a replace directive in go.mod to your local clone of uTLS, or use a tagged version with suffix -wasm (e.g., v1.6.2-wasm) to make sure it is tagged from the correct branch.
