debounce-promise-with-cancel

A debounce utility for functions returning promises with an option to cancel

Why?

I needed a simple utility for debouncing fetch calls with the ability to cancel requests in case of errors

Instalation and usage

Install:

npm install debounce-promise-with-cancel

Import:

import { debounce } from 'debounce-promise-with-cancel'

or as default import

import debounce from 'debounce-promise-with-cancel'

or as commonjs

const debounce = require('debounce-promise-with-cancel')

Usage:

const debouncedFetch = debounce(fetchData, 500)

...
// use debouncedFetch just as you would use fetchData
// when you need to cancel just 
debouncedFetch.cancel()
