simple-dom-listener
Simplified helpers to add/remove dom listeners without having to keep a reference to the listener itself to remove it
Features
- Very simple api,
on
,off
methods to add and remove dom listeners - The
on
method returns a function that you can use to remove the listener without having to pass the event name and the listener function
Installation
npm install simple-dom-listener
Usage
import { on } from 'simple-dom-listener';
// add a listener to the document element
const removeListener = on(document, 'click', (event) => {
console.log(event);
});
// later the returned function can be used
// to remove the event listener, without having to keep a reference to the listener
removeListener();
// a single listener for multiple events can be added
const off = on(document, ['click', 'keyup'], (event) => {
console.log(event);
});
// later calling the returned off function listeners can be removed without having to keep a reference to the listener itself
The returned function to remove the listener is very useful in React for example, as it can be used in the useEffect
cleanup function
useEffect(() => {
const off = on(document, 'click', (event) => {
console.log(event);
});
return off;
}, []);
// or more simplified as
useEffect(() => {
return on(document, 'click', (event) => {
console.log(event);
});
}, []);
