A tiny state manager for React, React Native, Preact, Vue, Svelte, Solid, Lit, Angular, Alpine, and vanilla JS. It uses many atomic stores and direct manipulation.

• Small. Less than 1 KB. Zero dependencies.
• Fast. With small atomic and derived stores, you do not need to call the selector function for all components on every store change.
• Tree Shakable. The chunk contains only stores used by components in the chunk.
• Was designed to move logic from components to stores.
• It has good TypeScript support.

It has many smart stores with built-in logic inside:

• Async computed store to fetch data or create chains of async operations.
• Persistent store to save data to localStorage and synchronize changes between browser tabs.
• Router store to parse URL and implements SPA navigation.
• Deep Map store to put big nested object/arrays and change keys by path.
• I18n library based on stores to make application translatable.
• Query store that helps you with smart remote data fetching.
• Logux Client: stores with WebSocket sync and CRDT conflict resolution.
• Immer plugin to enable immutable state updates using Immer.
