What is kew?

The 'kew' npm package is a lightweight promise library for Node.js that provides a simple and efficient way to handle asynchronous operations. It is designed to be fast and easy to use, offering a minimalistic API for creating and managing promises.

What are kew's main functionalities?

Creating Promises

This feature allows you to create promises using the 'kew' library. The example demonstrates how to create a deferred object, resolve it after a timeout, and handle the resolved value using the 'then' method.

const Q = require('kew');

function asyncTask() {
  const defer = Q.defer();
  setTimeout(() => {
    defer.resolve('Task completed');
  }, 1000);
  return defer.promise;
}

asyncTask().then(result => {
  console.log(result); // 'Task completed'
});

Chaining Promises

This feature allows you to chain multiple promises together. The example demonstrates how to chain two asynchronous tasks, where the second task starts only after the first task is completed.

const Q = require('kew');

function firstTask() {
  const defer = Q.defer();
  setTimeout(() => {
    defer.resolve('First task completed');
  }, 1000);
  return defer.promise;
}

function secondTask() {
  const defer = Q.defer();
  setTimeout(() => {
    defer.resolve('Second task completed');
  }, 1000);
  return defer.promise;
}

firstTask()
  .then(result => {
    console.log(result); // 'First task completed'
    return secondTask();
  })
  .then(result => {
    console.log(result); // 'Second task completed'
  });

Handling Errors

This feature allows you to handle errors in asynchronous operations. The example demonstrates how to create a promise that rejects with an error and how to handle the error using the 'fail' method.

const Q = require('kew');

function asyncTaskWithError() {
  const defer = Q.defer();
  setTimeout(() => {
    defer.reject(new Error('Something went wrong'));
  }, 1000);
  return defer.promise;
}

asyncTaskWithError()
  .then(result => {
    console.log(result);
  })
  .fail(error => {
    console.error(error.message); // 'Something went wrong'
  });
