What is element-resize-detector?

The element-resize-detector npm package is a utility for detecting changes in the size of HTML elements. It provides a way to listen for resize events on any DOM element, which can be useful for responsive design, dynamic content adjustments, and more.

What are element-resize-detector's main functionalities?

Basic Resize Detection

This feature allows you to listen for resize events on a specific DOM element. When the element is resized, the provided callback function is executed.

const elementResizeDetectorMaker = require('element-resize-detector');
const erd = elementResizeDetectorMaker();

const element = document.getElementById('myElement');
erd.listenTo(element, function(element) {
  console.log('Element resized:', element);
});

Unlisten to Resize Events

This feature allows you to stop listening to resize events on a specific DOM element. This can be useful for cleanup or when the resize detection is no longer needed.

const elementResizeDetectorMaker = require('element-resize-detector');
const erd = elementResizeDetectorMaker();

const element = document.getElementById('myElement');

function onResize(element) {
  console.log('Element resized:', element);
}

erd.listenTo(element, onResize);

// Later, if you want to stop listening to resize events
erd.uninstall(element);

Batch Listening

This feature allows you to listen for resize events on multiple elements at once. The provided callback function is executed whenever any of the elements are resized.

const elementResizeDetectorMaker = require('element-resize-detector');
const erd = elementResizeDetectorMaker();

const elements = document.querySelectorAll('.resize-listen');

function onResize(element) {
  console.log('Element resized:', element);
}

elements.forEach(element => erd.listenTo(element, onResize));
