WebAssembly for Proxies (GoLang host implementation)

The GoLang implementation for proxy-wasm, enabling developer to run proxy-wasm extensions in Go.

This project is a restructured version of the original MOSN implementation. It follows the actual C++ host and sdk implementation of proxy wasm as there is no official spec of proxy wasm.

Run Example

• build and run host

cd runtime/wazero/example
go run .

• send http request

curl http://127.0.0.1:2045/

• host log

receive request /
print header from server host, User-Agent -> [curl/7.64.1]
print header from server host, Accept -> [*/*]
[http_wasm_example.cc:33]::onRequestHeaders() print from wasm, onRequestHeaders, context id: 2
[http_wasm_example.cc:38]::onRequestHeaders() print from wasm, Accept -> */*
[http_wasm_example.cc:38]::onRequestHeaders() print from wasm, User-Agent -> curl/7.64.1
