The advancement of WASI, the WebAssembly System Interface, is key to pushing WebAssembly beyond the browser - from the Cloud to the Edge - allowing developers to build applications that are capable of running in a wide range of architectures and interfacing with an array of systems. One of the most exciting developments has been WASI’s networking support, which will unleash a whole new set of applications. In this session, we’ll explore the current state of WASI networking and cover the recent implementation of sock_accept(). Next, we’ll demonstrate a Wasm server using the Rust mio framework, along with some examples of networked applications. Finally, we’ll discuss the next steps towards building a full fledged networking API and the future of network-enabled WebAssembly applications, including some considerations with regards to deploying network identities and security.
