Volve

Tiny, Performant Debounce and Throttle Functions.

Why use these functions?

• Volve avoids the use of setTimeout and setInterval for efficency with the exception of the trail option when using debounce.

• No clutter.

• Built with ES6.

• UMD, CJS and ES6 support.

• Supports all browsers from IE5+ with the use of requestFrame.

• npm i --save volve

• yarn add volve --save

Debounce:

volve.debounce(<callback>,<delay>,<lead>)

import { debounce } from 'volve'

const helloWorld = (e) => {console.log('Hello World Debounced!', e.target)}
const debounceHelloWorld = debounce(helloWorld, 1000)  // Can only click 1 second after your last click.

document.body.addEventListener('click',debounceHelloWorld, false)
// Hello World! <div id="some-element-you-clicked"></div>

By default debounce will trail with the first function call, if the lead option {Boolean} is enabled, the callback will be fired after the last batch of calls that fall within conjoining delays.

Throttle:

volve.throttle(<callback>,<limit>)

import { throttle } from 'volve'

const helloWorld = (e) => {console.log('Hello World Throttled!', e.target)}
const throttleHelloWorld = throttle(helloWorld, 1000) // Can only click once in every second.

document.body.addEventListener('click',throttleHelloWorld, false)
// Hello World! <div id="some-element-you-clicked"></div>

In the two examples above debounce will make the user wait 1000ms until they can trigger a future call. Throttle will only allow the user trigger a call once within every 1000ms period.
