CGO-less Foreign Function Interface with WebAssembly

Explore CGO-less Foreign Function Interface (FFI) using WebAssembly in this GopherCon 2022 talk by Takeshi Yoneda. Learn about the basics of WebAssembly, its potential for achieving FFI in Go projects, and the current state of the Go ecosystem surrounding it. Discover wazero, an open-source WebAssembly runtime purely written in Go, which offers a secure and flexible approach to FFI without relying on CGO. Through a live demo, gain insights into implementing CGO-less FFI with WebAssembly, and delve into the intricacies of wazero's WebAssembly to machine code compiler and virtual machine implementation. Understand how to leverage this technology in your own Go projects, enabling cross-compilation and execution of applications written in other languages while maintaining Go's benefits.
