@types/bluebird
Advanced tools
Package description
The @types/bluebird package provides TypeScript type definitions for Bluebird, a powerful, full-featured Promise library that focuses on innovative features and performance. These type definitions allow TypeScript developers to use Bluebird in their projects with the benefits of type checking and IntelliSense support in their code editors.
Promise creation and usage
This feature demonstrates how to create a new Promise using Bluebird and handle its resolution with the `then` method.
import * as Bluebird from 'bluebird';
const promise = new Bluebird((resolve, reject) => {
resolve('Success!');
});
promise.then((result) => {
console.log(result);
});
Promise chaining
This feature shows how to chain multiple operations on a Promise, transforming its value step by step.
import * as Bluebird from 'bluebird';
Bluebird.resolve(1)
.then((result) => result + 1)
.then((result) => result * 2)
.then((result) => console.log(result)); // Outputs: 4
Error handling
This feature illustrates how to handle errors in Promise operations using the `catch` method, specifically catching instances of the Error class.
import * as Bluebird from 'bluebird';
Bluebird.reject(new Error('Failed'))
.catch(Error, (error) => {
console.error(error.message);
});
Q is a library for creating and managing promises in JavaScript. It's similar to Bluebird but differs in its API and performance characteristics. Bluebird is generally considered to have better performance and more features.
The es6-promise package is a polyfill for the ES6 Promise specification. It provides basic Promise functionality but lacks the advanced features and performance optimizations found in Bluebird.
This package is a simple implementation of Promises. It is lightweight and straightforward but does not offer the extensive feature set or the performance optimizations of Bluebird.
