perfect-debounce

An improved debounce function with Promise support.

• Well tested debounce implementation
• Native Promise support
• Avoid duplicate calls while promise is being resolved
• Configurable trailing and leading behavior

Usage

Install package:

# npm
npm install perfect-debounce

# yarn
yarn add perfect-debounce

# pnpm
pnpm add perfect-debounce

Import:

// ESM
import { debounce } from 'perfect-debounce'

// CommonJS
const { debounce } = require('perfect-debounce')

Debounce function:

const debounced = debounce(async () => {
  // Some heavy stuff
}, 25)

When calling debounced, it will wait at least for 25ms as configured before actually calling our function. This helps to avoid multiple calls.

To avoid initial wait, we can set leading: true option. It will cause function to be immediately called if there is no other call:

const debounced = debounce(async () => {
  // Some heavy stuff
}, 25, { leading: true })

If executing async function takes longer than debounce value, duplicate calls will be still prevented a last call will happen. To disable this behavior, we can set trailing: false option:

const debounced = debounce(async () => {
  // Some heavy stuff
}, 25, { trailing: false })
