Advanced Features

Reacton's core is intentionally small -- reacton(), computed(), watch(), set(). But when your application grows, Reacton scales with you through a set of opt-in advanced features that cover enterprise-grade requirements.

Feature Overview

Feature	Description	Use Case
Middleware	Intercept reacton lifecycle events (init, read, write, dispose)	Logging, validation, analytics, persistence
Persistence	Auto-persist reacton values to storage	User preferences, auth tokens, cached data
History	Undo/redo with full action audit log	Form editing, drawing apps, time-travel debugging
State Branching	Git-like branching for state	Form preview, A/B testing, speculative updates
State Machines	Typed state/event transitions with guards	Auth flows, wizards, complex workflows
Modules	Group related reactons with lifecycle management	Feature isolation, team boundaries, lazy loading
Observable Collections	Reactive lists and maps with granular change events	Todo lists, user directories, inventories
Multi-Isolate	Share state across Dart isolates	Heavy computation, background processing

Progressive Complexity

You do not need to use any of these features to build a great app with Reacton. They are additive -- adopt them one at a time as your requirements demand.

Level 1: reacton() + computed() + watch()           ← 80% of apps
Level 2: effects, selectors, async reactons          ← derived state, API calls
Level 3: middleware, persistence, history, branching  ← enterprise features

What's Next

• Middleware -- Intercept and transform reacton operations
• Persistence -- Auto-save state to disk
• History -- Add undo/redo to any reacton
