throttleit
Advanced tools
Package description
The throttleit package is a utility that allows you to throttle a function, meaning it limits the rate at which a function can fire. This is particularly useful for handling repetitive events that you want to control, such as window resizing, scrolling, or keypresses in a performant way.
Throttling function calls
This code sample demonstrates how to use throttleit to throttle a window resize event handler. The onResize function will not be called more than once every 200 milliseconds, no matter how often the resize event fires.
const throttle = require('throttleit');
function onResize(event) {
console.log('Window resized.');
}
window.addEventListener('resize', throttle(onResize, 200));lodash.throttle is a function from the popular Lodash library that provides a similar throttling functionality. It is often used for the same purposes as throttleit but comes as part of a larger utility library, which might be more suitable for projects that already use Lodash for other utilities.
underscore.throttle is a function from the Underscore.js library that also offers throttling capabilities. Like lodash.throttle, it is part of a larger set of utility functions. It is a good choice for projects that use Underscore.js.
Bottleneck is a package that is more focused on rate-limiting and not just throttling. It can be used to limit the execution of functions to a maximum number of times per interval, which is useful for managing API rate limits or other scenarios where you need a more robust solution than simple throttling.
Readme
Throttle a function to limit its execution rate
npm install throttleit
import throttle from 'throttleit';
// Throttling a function that processes data.
function processData(data) {
console.log('Processing:', data);
// Add data processing logic here.
}
// Throttle the `processData` function to be called at most once every 3 seconds.
const throttledProcessData = throttle(processData, 3000);
// Simulate calling the function multiple times with different data.
throttledProcessData('Data 1');
throttledProcessData('Data 2');
throttledProcessData('Data 3');
Creates a throttled function that limits calls to the original function to at most once every wait milliseconds. It guarantees execution after the final invocation and maintains the last context (this) and arguments.
Type: function
The function to be throttled.
Type: number
The number of milliseconds to throttle invocations to.
