@kwsites/promise-deferred

What is @kwsites/promise-deferred?

@kwsites/promise-deferred is a utility package that provides a simple way to create deferred promises. This can be useful in scenarios where you need to create a promise and resolve or reject it at a later time, outside of the initial promise executor function.

What are @kwsites/promise-deferred's main functionalities?

Creating a Deferred Promise

This feature allows you to create a deferred promise that can be resolved or rejected at a later time. The code sample demonstrates creating a deferred promise, simulating an asynchronous operation with setTimeout, and resolving the promise after 1 second.

const { deferred } = require('@kwsites/promise-deferred');

const def = deferred();

// Simulate an asynchronous operation
setTimeout(() => {
  def.resolve('Success!');
}, 1000);

// Use the promise
async function asyncOperation() {
  const result = await def.promise;
  console.log(result); // Outputs: 'Success!'
}

asyncOperation();

Handling Deferred Promise Rejection

This feature allows you to handle the rejection of a deferred promise. The code sample demonstrates creating a deferred promise, simulating an asynchronous operation with setTimeout, and rejecting the promise after 1 second. The async function catches and logs the error.

const { deferred } = require('@kwsites/promise-deferred');

const def = deferred();

// Simulate an asynchronous operation
setTimeout(() => {
  def.reject(new Error('Failure!'));
}, 1000);

// Use the promise
async function asyncOperation() {
  try {
    const result = await def.promise;
  } catch (error) {
    console.error(error.message); // Outputs: 'Failure!'
  }
}

asyncOperation();
