Pulse v0.1.1

v0.1.1 (Initial Base Release)

We are excited to announce the first public release of Pulse, a semantic reactivity system for modern applications. This release establishes the core primitives and ecosystem under the new @pulse-js namespace.

📦 Packages

• @pulse-js/core: The reactivity engine.
• @pulse-js/react: React 18+ integration hooks.
• @pulse-js/tools: Visual debugging suite (formerly devtools).

Features

Core Reactivity

• Sources: Primitive containers for state values.
• Guards: First-class "Conditions" that track status (ok, fail, pending) and failure reasons.
• Composition: Logic helpers guard.all, guard.any, guard.not, and guard.compute.
• Async Support: Native Promise handling for async guards.
• SSR: Isomorphic evaluate (server) and hydrate (client) methods.

React Integration

• usePulse Hook: Universal hook for both Sources and Guards.
• Concurrent Mode: Built on useSyncExternalStore for safe concurrent updates.
• Smart Re-renders: Components only update when semantic state changes.

Developer Experience

• Pulse Tools: A zero-config, draggable overlay for inspecting the reactive graph.
• Type Safety: Full TypeScript support with inferred types.

Getting Started
