http

Experimental HTTP Client Example

NB: this example uses an experimental wasmtime-http that incorporates a highly experimental HTTP client library that is not yet part of the WASI specification. Use at your own risk, things are likely to change drastically in the future.

Building

tinygo build -wasm-abi=generic -target=wasi -o main.wasm

Running

wasmtime --wasi-modules=experimental-wasi-http main.wasm

Regenerating the code

git clone https://github.com/WebAssembly/wasi-http
cd wasi-http
git checkout 6c6855a
cd ../
wit-bindgen tiny-go wasi-http/wit -w proxy --out-dir proxy

Note that there is currently a bug in wit-bindgen which prevents this from working correctly, it needs a small edit to add a typedef.

TODO: extract this out into a general purpose library
