Cortex is a lightweight JavaScript library providing an immutable data store for managing deeply nested data structures in React applications. It supports one-directional data flow with efficient batch updates and simple APIs for traversing and updating nested values.
Use cases
- manage deeply nested state in React apps
- immutable data store for React components
- fast shouldComponentUpdate comparisons with immutable data
- one-directional data flow without full Flux
- update nested arrays and objects from root
- lightweight state management for small React projects
When to choose
- building a legacy React app with deeply nested mutable-style data
- you want a tiny (~4.5kB) immutable state container with simple APIs
- you prefer one-way data flow without Flux/Redux boilerplate
When to avoid
- starting a new modern React project - use Redux, Zustand, or Immer instead
- you need active maintenance or community support - last release was 2018
- your app uses React hooks and modern state patterns
