A minimal deferred library that written in typescript
This deferred library can be used by es module, commonjs module and typescript module
Examples
Usage in es module, file with .mjs or .js extension
When .js extension used, the value of module property in package.json
should be module.
import { Deferred } from '@esutils/deferred';
async function demo() {
const defer = new Deferred();
setTimeout(() => {
defer.resolve();
});
console.log(`Start ${Date.now()}`);
await defer.promise;
console.log(`End ${Date.now()}`);
}
demo();
Usage in commonjs module, file with .cjs or .js extension
When .js extension used, the value of module property in package.json
should be commonjs or not specified.
const { Deferred } = require('@esutils/deferred');
async function demo() {
const defer = new Deferred();
setTimeout(() => {
defer.resolve();
});
console.log(`Start ${Date.now()}`);
await defer.promise;
console.log(`End ${Date.now()}`);
}
demo();
Usage in typescript module, file with .ts extension
import { Deferred } from '@esutils/deferred';
async function demo() {
const defer = new Deferred<void>();
setTimeout(() => {
defer.resolve();
});
console.log(`Start ${Date.now()}`);
await defer.promise;
console.log(`End ${Date.now()}`);
}
demo();
