Readme
Delay execution using Promises.
This library implements a sleep
function that uses
setTimeout
under the hood to create a Promise
that resolves after a specified number of milliseconds.
Contrary to the bare setTimeout
function, this library
also supports delays greater than 2147483647 (0x7fffffff, ~24.8 days).
npm install @cdellacqua/sleep
Basic usage example:
import {sleep} from '@cdellacqua/sleep';
sleep(1000).then(() => console.log('see you in a sec!'));
Same example, with await:
import {sleep} from '@cdellacqua/sleep';
async function example() {
await sleep(1000);
console.log('see you in a sec!');
}
Abort timeout after 500ms, rejecting the promise:
import {sleep} from '@cdellacqua/sleep';
async function example() {
try {
await sleep(1000, {signal: AbortSignal.timeout(500)});
} catch (err) {
console.log('see you in half a sec!');
}
}
Skip timeout after 500ms:
import {sleep} from '@cdellacqua/sleep';
async function example() {
// Note the `.catch(...)`!
await sleep(1000, {signal: AbortSignal.timeout(500)}).catch(() => {});
console.log('see you in half a sec!');
}
Abort timeout when an event happens, rejecting the promise:
import {sleep} from '@cdellacqua/sleep';
async function example() {
const controller = new AbortController();
window.addEventListener('click', () => {
controller.abort();
});
try {
await sleep(1000, {signal: controller.signal});
console.log('nobody clicked within 1 second!');
} catch (err) {
console.log('somebody clicked within 1 second!');
}
}
Use custom setTimeout/clearTimeout implementation:
import {sleep} from '@cdellacqua/sleep';
async function example() {
await sleep(1000, {
timeoutApi: {
setTimeout: (callback, ms) => setTimeout(callback, ms * 3),
clearTimeout: (timeoutId) => clearTimeout(timeoutId),
},
});
console.log('see you in... 3 seconds?');
}
