Andromeda - The Future Of TypeScript

セッショントラックAEnglish

In this talk, we’ll explore Andromeda, a new experimental JS/TS runtime that rethinks what a lightweight execution engine can be. You’ll get a behind-the-scenes look at how Andromeda works, why it exists, and what makes it fundamentally different from Node.js or Deno. We’ll talk about its architecture, how it handles TypeScript natively, and the motivations behind building a runtime focused on simplicity and transparency. Whether you're a runtime nerd, a systems programming enthusiast, or just curious about where the JavaScript ecosystem could go next, this session will spark new ideas about what’s possible when you strip a runtime down to its essentials — and rebuild it with Rust.
