Effector
#frontend
Effector is a reactive state manager for JavaScript and TypeScript with stores, events, and effects as first-class concepts. It emphasizes explicit dataflow, strong TypeScript inference, and tree-shakeable modules—popular in React via bindings but not React-specific. Compared to Redux-style global reducers, Effector encourages smaller units of state and derived stores; pick it when you want reactive composition without a single giant reducer tree.
