A small React library providing a useContextSelector hook in userland, allowing components to select parts of a context value to avoid unnecessary re-renders. It emulates the proposed React Context selector API with support for Concurrent React.

Use cases

• avoid re-renders when using React Context
• select specific fields from context value in a component
• replace prop drilling with performant context
• use context with concurrent React rendering
• optimize large React apps with shared context state

When to choose

• you specifically need context-selector semantics matching React's concurrent behavior
• you want a drop-in userland implementation of the proposed useContextSelector RFC
• you're a library author needing selector-based context in a peer dependency

When to avoid

• you only want to avoid re-renders and don't care about context semantics - prefer Zustand or useSyncExternalStore
• you want a full state management solution rather than a context enhancement
• you can't add peer dependencies like scheduler
