Wraps an async function and ensure only last call will actually resolve/reject
npm install awesome-only-resolves-last-promise
``bash`
npm install --save awesome-only-resolves-last-promise
// or
yarn add awesome-only-resolves-last-promise
- Wraps an existing async function
- When calling the wrapped function multiple times consecutively, only the last returned promise will resolve and formerly returned promises will be cancelled (they won't resolve nor reject)
`typescript jsx
import { onlyResolvesLast } from 'awesome-only-resolves-last-promise';
const asyncFunction = async (arg: number, arg2: string) => {
await delay(100);
return val ${arg} ${arg2};
};
const wrappedAsyncFunction = onlyResolvesLast(asyncFunction);
const promise1 = wrappedAsyncFunction(1, '1');
const promise2 = wrappedAsyncFunction(2, '2');
const promise3 = wrappedAsyncFunction(3, '3');
// promise1 and promise2 will never resolve/reject
// promise3 will resolve in 100ms
``
Useful as an implementation detail of awesome-debounce-promise.
