From Signals to Ownership: Why I Built a Dataflow Kernel (opens in new tab)

When I first started building signal-kernel, I thought I was simply writing a signal library—a fine-grained reactive system not tied to any specific UI framework. On the surface, it had all the basic building blocks you would expect from a signal library: Core primitives: Signal, Computed, and Effect Mechanisms: dependency tracking and scheduling Extensions: async resources and framework adapters It could build a reactive graph, track dependencies, update derived state precisely when data cha...
