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
