toju-react-hooks

toju-react-hooks library is a tool designed to facilitate React application development by providing a series of custom hooks. These hooks are designed to address common problems and frequent usage patterns in application development, allowing developers to manage state, side effects, context, and more, efficiently and with less boilerplate code. The library focuses on improving code readability, component reusability, and performance optimization, ensuring that React applications are more maintainable and scalable.

Key features of toju-react-hooks include:

• View detection hook: useIsInView allows you to detect when an element is in the viewport, enabling you to perform actions such as lazy loading images or triggering animations only when elements are visible on the screen.
• Throttling hook: useThrottle helps manage performance by limiting the number of times a function is called over time, which is particularly useful for handling high-frequency events like scrolling or window resizing efficiently.
• Event handling hook: useEvent simplifies the process of adding and removing event listeners, ensuring that your components respond to user interactions and other events smoothly and without memory leaks. Easy to use: Each hook is designed to be simple and intuitive, making it easy to integrate into any React project. Whether you're building a complex web application or a straightforward React component, toju-react-hooks can help you create more responsive, performant, and maintainable code.

API

useCounter

Custom hook for managing numeric state with increment, decrement, and reset capabilities.

Parameters

• options: Object with the following property:
  • initialValue (optional, default = 0): The initial value of the counter.

Returns

UseCounterReturn: An object containing:

• value (number): The current value of the counter.
• reset (function): Resets the counter to its initial value.
• increment (function): Increments the counter by a specified value (default is 1).
• decrement (function): Decrements the counter by a specified value (default is 1).

Example Usage

1const { value, reset, increment, decrement } = useCounter({ initialValue: 10 });
2
3// Increment the counter
4increment();
5
6// Decrement the counter
7decrement();
8
9// Reset the counter to the initial value
10reset();

useEvent

Custom hook to memorize and optimize event handlers.

Parameters

• callback: Function to be memorized and called by the event handler.

Returns

• A memorized callback function that can be used as an event handler.

Example Usage

useIsInView

Custom hook that determines if a referenced element is within the viewport using the Intersection Observer API.

Parameters

• options: Object with the following properties:
  • ref (React.RefObject): A React ref attached to the element you want to check for visibility.
  • threshold (number | number[], optional): A single number or an array of numbers indicating at what percentage of the target's visibility the observer's callback should be executed.
  • rootMargin (string, optional): A string representing the margin around the root. Allows the callback to execute even if the target is not in the viewport but within this margin.
