Custom React hooks: a three-part series

A short series on custom React hooks I wrote in 2023. Each post covers one hook, the implementation, and a concrete use case. Nothing fancy — just patterns I kept reaching for.

Why custom hooks?

Hooks let you pull stateful logic out of components and reuse it. Custom hooks are the same idea: extract a pattern once, call it from anywhere.

Series outline

Part 1: useLocalStorage: persist React state in localStorage Keep theme, language, or other preferences across page reloads.

Part 2: useMouseCoords: track cursor position Read clientX / clientY from mousemove events in a reusable hook.

Part 3: useNetworkStatus: react to online/offline Listen to online and offline events and expose a boolean.
