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.
v3.0.0 (Stable) — The "Next-Gen AI" Release
This release introduces the industry's first AI-native and environment-aware asynchronous orchestration engine. Version 3.0.0 transforms AsyncFlowState from a resilience library into an autonomous, self-optimizing framework.
Autonomous AI Optimizations
- Flow DNA (Genetic Auto-Tuning): Eliminates manual configuration. Flows analyze P95 latency and failure rates to continuously evolve their own timeouts, retries, and stale times in production.
- Speculative Execution: UI branch prediction. Renders optimistic and real execution paths in parallel, with smooth animated morphing upon server conflict.
- Emotional UX (Sentiment Analysis): Automatically tracks rage-clicking, cursor hesitation, and form abandonment to dynamically throttle operations or simplify the UI for frustrated users.
Distributed & Edge Architecture
- Flow Mesh (Cross-Tab Coordination): Tabs form a local P2P network using
BroadcastChannel. Leader election ensures only one tab fetches data while followers read from the shared mesh cache. - Edge-First Native: Runtime-aware execution. Automatically detects Cloudflare Workers, Vercel Edge, or Deno, utilizing the Edge Cache API and splitting workloads between client and edge.
- Collaborative CRDT Flows: Built-in Last-Writer-Wins (LWW) conflict resolution for real-time multiplayer applications, ensuring eventual consistency across all clients.
Advanced Execution Patterns
- Flow Choreography (DAG): Declare complex, multi-step dependencies. The engine handles topological sorting (Kahn's algorithm), parallel execution, and partial failure rollbacks automatically.
- Ambient Intelligence: Flows monitor device telemetry (battery, CPU pressure, network type). Automatically defers heavy syncs on 2G networks or compresses payloads on low battery.
Enterprise DevTools
- Temporal Replay: High-resolution lifecycle snapshots. Time-travel debug complex async race conditions by scrubbing back and forth through execution history.
- Telemetry Dashboard: A zero-dependency, Shadow DOM overlay providing real-time flame graphs, cache hit rates, and AI healing events directly in the browser.
New Framework Adapters
We have officially expanded our framework support from 6 to 9 adapters, introducing native bindings for:
- Nuxt 3 (
@asyncflowstate/nuxt) - Remix (
@asyncflowstate/remix) - Astro (
@asyncflowstate/astro)
v2.0.2 (Previous Stable) — The "Complete Ecosystem" Update
Expanded the ecosystem from 6 to 9 framework adapters (adding Nuxt, Remix, and Astro). Standardized A11y announcements and reactive options across all bindings.
v2.0.0 — The "Universal" Release
The v2.0 release was a complete ground-up rewrite of AsyncFlowState. It transformed 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
AsyncIterablechunks 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
FlowProvideronce, and every flow in your app inherits them.
