How to use the default function from bluebird

bluebird.default is a function in the Bluebird library that can be used to create a new instance of a Promise.

How does bluebird.default work?

bluebird.default is a function in the Bluebird library that can be used to create a new instance of a Promise.

When bluebird.default is called, it takes a single argument, which is a function that is called with two parameters, resolve and reject. The function represents the asynchronous operation that the Promise represents.

Inside the function, the resolve function should be called when the operation succeeds, passing it the result of the operation. The reject function should be called when the operation fails, passing it an error object.

Once the Promise is created, it can be used to chain together asynchronous operations using methods such as then, catch, or finally.

By default, bluebird.default uses the global Promise implementation if it exists, or falls back to the built-in Promise implementation if it does not. However, this behavior can be customized using various options, such as cancellation, longStackTraces, or promisify.

Overall, bluebird.default provides a flexible and powerful way to create and work with Promises in JavaScript, allowing developers to write asynchronous code that is easier to read and reason about.

const Promise = require("bluebird");

// Create a new Promise that resolves after a timeout
const myPromise = new Promise((resolve, reject) => {
  setTimeout(() => {
    resolve("Promise resolved successfully");
  }, 1000);
});

// Chain together Promises using `then` and `catch`
myPromise
  .then((result) => {
    console.log("Promise result:", result);
    return "Next Promise resolved successfully";
  })
  .then((result) => {
    console.log("Next Promise result:", result);
    throw new Error("An error occurred");
  })
  .catch((error) => {
    console.log("Promise error:", error.message);
  });

In this example, we use bluebird.default to create and work with a Promise. We call new Promise with a function that sets up an asynchronous operation using setTimeout. The function calls resolve after a timeout of 1000ms, passing it a success message. We then chain together Promises using then and catch methods. The first then callback logs the resolved result of the initial Promise, and returns a new success message. The second then callback logs the resolved result of the second Promise, and throws an error. The catch callback logs the caught error. This example shows how bluebird.default can be used to create and work with Promises in JavaScript, allowing developers to write asynchronous code that is easier to read and reason about.
