A tiny JavaScript library providing transparent reactivity using ES6 Proxies, with observables and automatic reactions that re-run when observed state changes. It is framework-independent and supports 100% of the JavaScript language, including dynamic properties and delete.

Use cases

• build a reactive state layer without a framework
• auto-update UI when plain JS state changes
• replace setState-style boilerplate with transparent observables
• react to dynamic property additions and deletions
• integrate reactivity into a custom frontend framework

When to choose

• you want framework-agnostic reactivity with full JS language coverage
• you need a tiny, dependency-free observable library
• your target environments support ES6 Proxies

When to avoid

• you need to support browsers or environments without ES6 Proxy support
• you already use a framework with a built-in reactivity system
• you need a full state management solution with devtools and ecosystem
