Summary : Unleash the power of XMPP in order to build exciting, realtime, federated applications based on open standards in a secure and highly scalable fashion Key Features [*] Learn about the fundamentals of XMPP and be able to work with the core functionality both server-side and in the browser [*] Build a simple 1-to-1 chat (the “Hello World” of XMPP), explore multi-user chat, publish subscribe systems, and work with a decentralized social network [*]Author Lloyd Watkins is a member of the XMPP standards committee Book DescriptionXMPP (eXtensible Messaging and Presence Protocol) is a messaging protocol that enables communication between two or more devices via the Internet. With this book, developers will learn about the fundamentals of XMPP, be able to work with the core functionality both server-side and in the browser, as well as starting to explore several of the protocol extensions. You will not only have a solid grasp of XMPP and how it works, but will also be able to use the protocol to build real-world applications that utilize the power of XMPP. By the end of this book, you will know more about networking applications in general, and have a good understanding of how to extend XMPP, as well as using it in sample applications.What you will learn [*] Install and configure an XMPP server and use it to connect from a traditional desktop client and send a message [*] Build a simple server-side application that will respond to messages from our logged in desktop client [*] Install and run XMPP-FTW, connect to the server from the browser, and handle incoming/outgoing messages [*] Connect to a multi-user chat room, send/receive stanzas, add a room password, join a protected room, set the room's subject, and change a user s affiliation [*] Get to grips with the publish-subscribe extension of XMPP and use it to build a pusher system that can make any website real-time [*] Build a simple XMPP component and create an extension for XMPP-FTW that allows you to use your own custom format [*] Build an XMPP version of the classic game “Pong” Who this book is for If you want to learn about the fundamentals of XMPP, be able to work with the core functionality both server-side and in the browser then this book is for you.No knowledge of XMPP is required, or of TCP/IP networking. It's important that you already know how to build applications of some form, and are looking get a better understanding of how to implement XMPP for one or more of its many uses. You should be interested in the decentralized web, know HTML, and likely know JavaScript and NodeJS. You will probably know JSON, and hopefully XML (this is the native output of XMPP).

It is used primarily to power instant-messaging services such as Jabber and WhatsApp. In this way, it is similar to other protocols such as WebRTC, which enable near real-time communication between Internet-connected devices.With this book, developers will learn about the fundamentals of XMPP, be able to work with the core functionality both server-side and in the browser, as well as starting to explore several of the protocol extensions. By the end of this book, you will not only have a solid grasp of XMPP and how it works, but will also be able to use the protocol to build real-world applications that utilize the power of XMPP.

Summary : Pro JavaScript with MooTools is unlike any other JavaScript book on the market today. While similar books focus on either JavaScript as a language of the browser or how to use JavaScript frameworks, Pro JavaScript with MooTools fills the gap between these topics and moves beyond—exploring the advanced features of JavaScript and how the MooTools framework uses these features to further improve the language itself. The book itself takes a unique three-pronged approach. It first walks you through the advanced features of JavaScript and the MooTools framework, including native augmentation and type creation, a comprehensive discussion of JavaScript functions, object-oriented programming with native JavaScript and MooTools Classes, and the MooTools Class internals. You’ll then learn all about Javascript in the DOM: the Elements classes and its internals, the MooTools Event system, Selector engines and MooTools Slick, Ajax and the Request Object, and animation and the Fx classes. The final section really sets the book apart from all others, as it discusses JavaScript outside the browsers. You’ll take an in-depth look at CommonJS and MooTools, using MooTools outside the browser to build ORM, creating simple CommonJS applications via the MooTools Deck framework, and creating complex server-side applications using Raccoon.

Summary : Develop your JavaScript programming skills by learning strategies and techniques commonly used in modern full-stack application development Key Features Write and deploy full-stack applications efficiently with JavaScript Delve into JavaScript’s multiple programming paradigms Get up to speed with core concepts such as modularity and functional programming to write efficient code Book DescriptionIn depth knowledge of JavaScript makes it easier to learn a variety of other frameworks, including React, Angular, and related tools and libraries. This book is designed to help you cover the core JavaScript concepts you need to build modern applications. You'll start by learning how to represent an HTML document in the Document Object Model (DOM). Then, you'll combine your knowledge of the DOM and Node.js to create a web scraper for practical situations. As you read through further lessons, you'll create a Node.js-based RESTful API using the Express library for Node.js. You'll also understand how modular designs can be used for better reusability and collaboration with multiple developers on a single project. Later lessons will guide you through building unit tests, which ensure that the core functionality of your program is not affected over time. The book will also demonstrate how constructors, async/await, and events can load your applications quickly and efficiently. Finally, you'll gain useful insights into functional programming concepts such as immutability, pure functions, and higher-order functions. By the end of this book, you'll have the skills you need to tackle any real-world JavaScript development problem using a modern JavaScript approach, both for the client and server sides.What you will learn Apply the core concepts of functional programming Build a Node.js project that uses the Express.js library to host an API Create unit tests for a Node.js project to validate it Use the Cheerio library with Node.js to create a basic web scraper Develop a React interface to build processing flows Use callbacks as a basic way to bring control back Who this book is for If you want to advance from being a frontend developer to a full-stack developer and learn how Node.js can be used for hosting full-stack applications, this is an ideal book for you. After reading this book, you'll be able to write better JavaScript code and learn about the latest trends in the language. To easily grasp the concepts explained here, you should know the basic syntax of JavaScript and should've worked with popular frontend libraries such as jQuery. You should have also used JavaScript with HTML and CSS but not necessarily Node.js.
