This talk was recorded at Code BEAM America 2024, a conference by Code Sync https://codebeamamerica.com

WebAssembly is an up and coming technology with wide support and bright promise. But until recently, integrating with WebAssembly for something as simple as calling a function with a string was almost prohibitively difficult. That is in the process of changing: there are now multiple options to integrate Elixir and WebAssembly at a higher level in a more productive way. In this session, we’ll start with a brief (re-)introduction to WebAssembly and discuss the possibilities it unlocks for us as Elixir developers. We’ll see what the challenges are to integration and how they are addressed by open source projects like Extism and advances to WebAssembly itself such as the WebAssembly Component Model. We’ll explore this via concrete, thoroughly explained code examples. You will walk away from this talk with the knowledge of why and how you can integrate WebAssembly in your next Elixir application.

Let’s stay in touch!
