WAZERO NET

this project provider net/http for wazero, it not belong to wazero's official project

note: unsupport tinygo, because tinygo's gc has some problem for wasm

Dial's Conn can not convert to net.TCPConn,net.UDPConn

Install

go get github.com/labulakalia/wazero_net

Example

must use go version >= go1.24, because go1.24 will support go:wasmexport directive to export function

Install Required Go Version

go install golang.org/dl/go1.24rc1@latest
go1.24rc1 download

cd example
GOOS=wasip1 GOARCH=wasm go1.24rc1 build -buildmode=c-shared -o http.wasm http.go
GOOS=wasip1 GOARCH=wasm go1.24rc1 build -buildmode=c-shared -o net.wasm net.go
go1.24rc1 run example.go

Todo

• support listen ip
• add unit test

Some Limit or Bug

sleep sleep2 need call on multi goroutine syscall, or goroutinue can no scheduler,this is bug example code
