Plain-English Explanation: redux-react-hook

This library makes it easier to use Redux (a popular tool for managing app-wide data) inside React components. Instead of writing boilerplate code to connect your component to your Redux store, you can use simple hooks—lightweight functions that let you grab data and trigger actions in just a few lines.

Think of Redux as a central filing cabinet for your app's data. Normally, connecting a React component to that cabinet requires some ceremony. This library streamlines that by providing two main hooks: one that lets you read specific pieces of data from the store and automatically re-render when those pieces change, and another that gives you the ability to dispatch actions (instructions that update the store). You set it up once at the top of your app by wrapping your component tree with a provider, then any component nested inside can use these hooks to tap into your Redux store.

The most common use case is a component that needs to display some data from your store and respond to user actions. For example, a delete button might use the hook to grab whether the user has permission to delete something and what the item's name is, then dispatch an action when clicked. The library handles the bookkeeping of watching the store for changes and only re-rendering your component when the data it cares about actually changes.

One important note from the README: this is more experimental than the official Redux library (react-redux), which has been battle-tested in production apps. The README explicitly recommends sticking with react-redux for now unless you have a specific reason to try this. Also, you have to be careful to memoize your data-selection functions using React's useCallback to avoid accidental infinite loops—a quirk the maintainers acknowledge in their FAQ.
