This example demonstrates a reusable React hook, `useInterval`, that manages a timed callback for animations or periodic updates in a component. It accepts a callback function, a delay in milliseconds, and a dependency list, ensuring the interval resets whenever the callback or dependencies change. The hook relies on React’s `useEffect` and `useMemo` APIs to set up and clear a `setInterval` timer, returning a cleanup function to prevent memory leaks. The code shows a concise pattern for integrating interval-based logic into React projects, suitable for driving data-visualization updates or animations without external libraries.

React cheatsheet

This animated React cheatsheet presents reusable code patterns for hooks, state management, and component composition. The example uses React hooks including `useState`, `useEffect`, `useRef`, `useReducer`, and `useContext`, alongside custom hooks like `useTimeout` and higher-order components. It demonstrates conditional JSX rendering, callback-based state updates, and the containment pattern via props slots. The animation shows code snippets transitioning between sections, sourced from a gist by abernier.

Repeater triggers the onRepeat event multiple times at the speed interval.

This example demonstrates how a React `Repeater` component triggers its `onRepeat` callback repeatedly at a fixed `speed` interval, simulating a continuous animation loop. The component uses React’s `useEffect` hook to set up a `setInterval` that fires `onRepeat` at the specified millisecond rate, while respecting a `disabled` prop and an optional `emitFirst` flag that triggers the callback once immediately. It renders no visible output, serving purely as a timing utility. The example shows the `Repeater` API in action, where the interval is cleared on unmount or when dependencies change.

Hook that debounces values by discarding inputs that take less than the specified milliseconds between changes.

This example demonstrates a React hook that delays updates to a value until a specified number of milliseconds pass without new input, effectively debouncing rapid changes. The `useDebounce` function takes a `next` value and a delay `ms`, then uses `useState` to store the debounced result and `useEffect` with `setTimeout` to schedule the update, clearing the previous timer via `clearTimeout` when dependencies change. It returns the debounced value, enabling components to ignore frequent intermediate states, such as keystrokes or slider movements, until the user pauses. The code uses only React's core hooks, with no external libraries.

Hook that rotates the items of an Array over time like a news ticker tape.

This example demonstrates a React hook that continuously cycles through an array of items like a news ticker tape, presenting each value in sequence at a set interval. The hook, `useTickerTape`, takes an iterable and a speed in milliseconds, then maintains the current order of items in state. Using `useEffect` and `setTimeout`, it shifts the first item to the end of the array on each tick, triggering a re-render that displays the rotated list. The code relies on React’s `useState` and `useEffect` APIs, with the array spread operator to create immutable updates.

Hook that debounces useState() changes.

This React hook demonstrates how to debounce state updates from `useState` by wrapping the setter in a custom `useStateDebounce` function. It uses `useCallback`, `useRef`, and `useEffect` to manage a `window.setTimeout` and `window.clearTimeout` pair, delaying the `setState` call by a specified `ms` interval. The hook accepts an initial state value and returns the debounced state and setter, preventing rapid re-renders from frequent input changes. The example is implemented as a TypeScript `.tsx` file, showing the logic in isolation without external data sources or visualization libraries.

ReactJs hook that joins an Array of Elements with a separating Element.

This example demonstrates a React hook that inserts a separator element between each item in an array of JSX elements, producing a new array where the original items and separators alternate. The hook, `useArrayJoin`, uses `useMemo` to cache the result and relies on `Array.reduce` to iterate through the input array, placing the join element—generated by a callback function—between consecutive items. The code specifically leverages React’s JSX type system and the `useMemo` API to optimize re-renders, with the separator receiving a unique key based on the current index.

A hook that persists useState() to localStorage.

This example demonstrates a custom React hook that synchronizes a component’s state with the browser’s localStorage, enabling persistent data across page reloads. The hook, `useStateStorage`, initializes state with a provided default value and reads any stored JSON from localStorage on mount, updating the state if valid. It exposes a setter function that writes both the new state and its JSON-serialized form to localStorage. The code uses React’s `useState`, `useEffect`, and `useCallback` APIs to manage lifecycle and memoization, while leveraging `localStorage.getItem` and `localStorage.setItem` for storage operations.

Hook that increments a counter every time useState() is changed.

This example demonstrates a React hook that tracks how many times a component’s state value is updated. The hook, `useStateCount`, returns both the current value and an incrementing counter that increases each time `setValue` is called. It uses React’s `useState` to store a tuple of `[count, value]` and `useCallback` to memoize the update function, depending on the current count. The code is written in TypeScript and shows a pattern for monitoring state changes without external libraries, relying solely on React’s built-in hooks.
