Requires a WebAssembly runtime with WASI sockets preview support and compiling Go to the WASI target.
This project, go-wasi-socket, is a prototype that lets code written in the Go programming language communicate over the internet when it's running inside a special kind of sandboxed environment. Normally, if you build a web server or a networked tool in Go, it can directly access the computer's networking features. But when you run that same code inside a "WebAssembly" sandbox, a secure, isolated container often used to safely run untrusted or portable code, that direct access is blocked by default for security reasons. This project provides the missing link that lets the sandboxed Go code open network connections and send and receive data. At a high level, it bridges Go's networking capabilities with a new standard called WASI sockets. WASI is essentially a set of rules that allows sandboxed programs to safely ask the host system for permission to do things like read files or talk to the internet. By implementing this interface, the project enables Go programs compiled for WebAssembly to request and use those networking permissions, rather than being completely cut off from the outside world. The primary audience for this includes developers building tools that run safely in isolated environments, such as browser-based applications, serverless functions, or edge computing platforms. For example, if a company wants to run a lightweight Go service directly on a user's device or inside a strict cloud sandbox without risking the security of the underlying machine, they would compile that Go code to WebAssembly. This library would be what allows that isolated service to make external API calls or serve web requests. The repository doesn't go into further detail about its specific implementation or current limitations, other than noting that it is a prototype. This means it is likely an early-stage experiment meant to test how well Go can interact with the emerging networking standards for WebAssembly, rather than a finished, production-ready toolkit.
A prototype library that lets Go programs running inside WebAssembly sandboxes make network connections using the WASI sockets standard, enabling internet access in secure, isolated environments.
Mainly Go. The stack also includes Go, WebAssembly, WASI.
