What is native-promise-only?

The native-promise-only package is a lightweight implementation of the ES6 (ECMAScript 2015) Promise specification. It provides a way to handle asynchronous operations in JavaScript, allowing you to write cleaner and more manageable code. This package is particularly useful for environments that do not natively support Promises or for those who prefer a minimalistic implementation.

What are native-promise-only's main functionalities?

Basic Promise Usage

This code demonstrates the basic usage of a Promise. It creates a new Promise that resolves with the message 'Hello, World!' after 1 second. The .then() method is used to handle the resolved value.

const Promise = require('native-promise-only');

const promise = new Promise((resolve, reject) => {
  setTimeout(() => resolve('Hello, World!'), 1000);
});

promise.then((message) => {
  console.log(message); // 'Hello, World!'
});

Chaining Promises

This code demonstrates how to chain multiple .then() methods to handle a sequence of asynchronous operations. Each .then() method returns a new Promise, allowing for a chain of operations.

const Promise = require('native-promise-only');

const promise = new Promise((resolve, reject) => {
  setTimeout(() => resolve(1), 1000);
});

promise
  .then((value) => {
    console.log(value); // 1
    return value + 1;
  })
  .then((value) => {
    console.log(value); // 2
    return value + 1;
  })
  .then((value) => {
    console.log(value); // 3
  });

Handling Errors

This code demonstrates how to handle errors in Promises using the .catch() method. If the Promise is rejected, the .catch() method will be called with the error.

const Promise = require('native-promise-only');

const promise = new Promise((resolve, reject) => {
  setTimeout(() => reject(new Error('Something went wrong!')), 1000);
});

promise
  .then((value) => {
    console.log(value);
  })
  .catch((error) => {
    console.error(error.message); // 'Something went wrong!'
  });
