SDKs

Use this section when the goal is to build against SOF from application code instead of wiring the Rust runtime manually.

Right now the public SDK story is:

  • @lythaeon-sof/sdk for TypeScript application authoring
  • native runtime host packages that the TypeScript SDK resolves automatically at install/runtime

The important boundary is simple:

  • TypeScript owns app composition and business callbacks
  • Rust still owns ingress, queues, replay, fan-in, gossip, direct shreds, and the runtime hot path

That means the SDK is meant to feel simple without turning SOF into a JavaScript reimplementation.

What This Track Is For

  • teams that want to write SOF apps in TypeScript
  • teams that want the Rust runtime underneath without thinking about Cargo
  • teams that need provider ingress, fan-in, gossip, or direct shreds from a simpler application API

What This Track Is Not

  • a full foreign-language replacement for the Rust workspace
  • a promise that Python is already at feature parity
  • a bypass around SOF runtime ownership

The TypeScript SDK is intentionally a thin application-facing layer over the existing Rust runtime.
