WIT, or Wasm Interface Types, allows WebAssembly modules to communicate with each other using complex data types. WIT is a language agnostic interface definition language (IDL) that enables composing WebAssembly components, regardless of source language, using language-specific bindings. If you're using a WIT-generated set of language bindings it will feel just like using a regular language SDK. If you're writing your own WIT, then this guide is for you!

One of the most formidable barriers in adopting and building event-sourced systems is learning to live with, and even embrace, the restrictions on component behavior. As it turns out, the same restrictions that make WebAssembly so powerful line up perfectly with event sourcing requirements.

Some thoughts and reflection on my first day using Wasm components for something more involved than hello world.

An examination of how wasifills—a component adapter pattern like polyfills, but for components—can help bridge the gap between today's rapidly changing standards landscape and the future of interoperable components facilitated with wit and wit worlds. It's an amazing time to be on the bleeding edge of the WebAssembly adoption curve, but it's not without risk.
