Introducing Zustand (State Management) – Frontend Masters Blog

Zustand is a minimal state management library for React that offers a simpler alternative to React Context with better performance. Unlike Context, which re-renders all consumers when any state changes, Zustand allows selective subscriptions through selector functions, reducing unnecessary re-renders. The library provides a clean API using a create function to define stores and supports async operations, external state access, and fine-grained subscriptions. The post demonstrates three implementations of the same task management app: vanilla React Context, basic Zustand usage, and optimized Zustand with selectors, showing how proper selector usage prevents excessive re-rendering.
