Reactive EngineThe logical core of the project

High-performance reactive state management and utils

Minimal Re-renders

Components subscribe strictly to specific primitive signals (`Signal`) or computed properties (`Computed`) rather than the entire state object. A change in a single signal updates *only* the component that actually reads it.

O(1) Computations

Computed properties are lazy. They are never recalculated until their underlying source signals change.

Automatic Batching

The engine groups multiple signal updates into single batches via microtasks. Network resources or heavy side-effects won't trigger 10 times in a row when 10 signals are updated within the same cycle.

Smart Asynchrony

The built-in `resource` tool orchestrates an `AbortController` out of the box, automatically cancelling previous pending network requests whenever dependencies change.
