@offirmo/deferred v4.0.1

A simple, TypeScript typed implementation of the deferred pattern

This is seldom used but useful sometimes.

Be sure to review your options before using the deferred pattern over a simple promise.

Note: no dependencies!

Usage

import Deferred from '@offirmo/deferred'

const promise = new Deferred<T>()

// it's an unresolved promise, you can attach stuff
promise.then(console.log).catch(...)

// later:
promise.resolve(...)
promise.reject(new Error('Foo!'))
