Release Notes

Stay informed about the evolution of AsyncFlowState. We're committed to building the most predictable, resilient, and developer-friendly async orchestration engine in the world.

v2.0.0 (Stable) — The "Universal" Release

Released on April 15, 2026

The v2.0 release is a complete ground-up rewrite of AsyncFlowState. It transforms the library from a React hook collection into a framework-agnostic behavior engine with native adapters for every modern frontend stack.

The New Universal Architecture

• Framework-Agnostic Core: The logic engine is now 100% decoupled from the UI layer. This ensures identical behavior whether you're using React, Vue, or Angular.
• Native Adapters: Six specialized packages supporting React, Next.js, Vue 3, Svelte, Angular, and SolidJS.
• Zero-Dependency: The core engine remains lightweight with zero external dependencies, making it safe for any production environment.

Resilience Engineering

• Dead Letter Queue (DLQ): Failed operations are no longer lost. They are automatically pooled in the DLQ for manual retry or auditing.
• Circuit Breakers: Prevent cascading failures by automatically pausing flows when a downstream service is down. State persists across page refreshes.
• Exponential Backoff: Smart retry logic with jitter to protect your backend while improving success rates for users.

Premium UX Patterns

• Optimistic UI 2.0: One-line implementation of "Success First" interactions. If the backend fails, AsyncFlowState performs a Deep-Diff Rollback of your local state automatically.
• Ghost Queues: Handle "spam-clicking" by queuing actions in the background. The UI remains responsive while the engine processes actions sequentially.
• Purgatory (Undo Support): Configurable delay for destructive actions (like "Delete"). Provides a native "Undo" grace period before committing the async operation.
• AI Skeletons: Purpose-built loading states for AI/LLM streaming. Dynamically responds to partial AsyncIterable chunks as they arrive.
• Cross-Tab Sync: Your async state is now shared across browser tabs. If a "Save" succeeds in Tab A, the button state in Tab B updates instantly.

Developer Experience (DX)

• Visual Time-Travel Debugger: A new DevTools-style debugger to inspect flow history, inputs, outputs, and state transitions in real-time.
• 100% Type Safety: Pure TypeScript implementation with advanced generics that infer your inputs and error types automatically.
• Unified Configuration: Set global behaviors (like global error handlers) via FlowProvider once, and every flow in your app inherits them.
