abdus / AbortController-in-action.js
Created July 27, 2020 09:17
An example of how to implement AbortController in a function which returns Promise.
/* this function would return a Promise
* which would resolve with value `hello`
* after 4s
*/
function abortTask({ signal }) {
return new Promise((resolve, reject) => {
// 1. check if it's already aborted
if (signal && signal.aborted) {
return reject(new DOMException('`signal` is in `aborted` state', 'ABORT_ERR'));
}
