WebAssembly for Gophers: from Wasm to Asm and back!

Have you ever heard about WebAssembly?

WebAssembly is a compilation target meant for efficient compilation, portability, and safe execution. A WebAssembly runtime is a language VM that is small and easy to embed.

All cool gophers know they can compile their Go software into Wasm using the Go compiler and TinyGo. But did you know that you can also embed Wasm binaries in your applications? Did you know that you can use Wasm to dynamically load code at runtime without giving up memory safety and performance?

In this talk, we will first show how WebAssembly might be relevant to your use cases, such as providing extension points to your end users or importing foreign libraries.

We will then dive deep into the implementation of one such language VM specifically designed for embedding in Go, and show how a WebAssembly function is compiled into efficient native code and then invoked without sacrificing the portability, safety, and integrity of your Go code base.

Join this session for a journey from Wasm to Asm from the eye of a gopher!
