Key Features Over 90 practical recipes to help you write clean and maintainable JavaScript codes with the latest ES8 Leverage the power of leading web frameworks like Node and React to build modern web apps Features comprehensive coverage of tools and techniques needed to create multi-platform apps with JavaScript Book Description JavaScript has evolved into a language that you can use on any platform. Modern JavaScript Web Development Cookbook is a perfect blend of solutions for traditional JavaScript development and modern areas that developers have lately been exploring with JavaScript. This comprehensive guide teaches you how to work with JavaScript on servers, browsers, mobile phones and desktops. You will start by exploring the new features of ES8. You will then move on to learning the use of ES8 on servers (with Node.js), with the objective of producing services and microservices and dealing with authentication and CORS. Once you get accustomed to ES8, you will learn to apply it to browsers using frameworks, such as React and Redux, which interact through Ajax with services. You will then understand the use of a modern framework to develop the UI. In addition to this, development for mobile devices with React Native will walk you through the benefits of creating native apps, both for Android and iOS. Finally, you'll be able to apply your new-found knowledge of server-side and client-side tools to develop applications with Electron. What you will learn Use the latest features of ES8 and learn new ways to code with JavaScript Develop server-side services and microservices with Node.js Learn to do unit testing and to debug your code Build client-side web applications using React and Redux Create native mobile applications for Android and iOS with React Native Write desktop applications with Electron Who this book is for This book is for developers who want to explore the latest JavaScript features, frameworks, and tools for building complete mobile, desktop and web apps, including server and client-side code.

There's no doubt that the JavaScript ecosystem changes fast. Not only are new tools and frameworks introduced and developed at a rapid rate, the language itself has undergone big changes with the introduction of ES2015 (aka ES6). Understandably, many articles have been written complaining about how difficult it is to learn modern JavaScript development these days. We're aiming to minimize that confusion with this set of books on modern JavaScript. This book presents modern JavaScript best practice, utilizing the features now available in the language that enable you to write more powerful code that is clean, performant, maintainable, and resusable. It contains: The Anatomy of a Modern JavaScript Application by James Kolce Clean Code with ES6 Default Parameters & Property Shorthands by Moritz Kruger JavaScript Performance Optimization Tips: An Overview by Ivan CuriC JavaScript Design Patterns: The Singleton by Samier Saeed JavaScript Object Creation: Patterns and Best Practices by Jeff Mott Best Practices for Using Modern JavaScript Syntax by M. David Green Flow Control in Modern JS: Callbacks to Promises to Async/Await by Craig Buckler JavaScript's New Private Class Fields, and How to Use Them by Craig Buckler This book is for all front-end developers who wish to improve their JavaScript skills. You'll need to be familiar with HTML and CSS and have a reasonable level of understanding of JavaScript in order to follow the discussion.

Long description: In einer Welt von Gadgets, die verwirrend viel können, führt Sie dieses Buch zurück auf die Grundlagen der Technik. Es zeigt Ihnen, wie Sie Ihren eigenen Scanner, Plotter, Ihre Kamera und vieles mehr mit ein paar Alltagsgegenständen und dem Espruino Mikrocontroller selbst bauen können.Mit der Internet-Programmiersprache JavaScript und einem Espruino – oder einem kompatiblen Mikrocontroller – realisieren Sie viele spannende Projekte und verstehen so, wie die Dinge von Grund auf funktionieren. Dabei entwickeln Sie Ihre Fähigkeiten und Kenntnisse weiter, sodass Sie in der Lage sind, auch eigene Ideen zum Leben zu erwecken und neue, clevere Objekte zu verwirklichen.Sie brauchen keine besonderen Fähigkeiten, Werkzeuge oder teure Komponenten, um interessante Geräte herzustellen. Dieses Buch ist perfekt für Einsteiger, aber auch für fortgeschrittene Maker geeignet. Es vermittelt Ihnen die Konzepte, die hinter den Alltagsgegenständen stecken, erklärt die Grundlagen der JavaScript-Progammierung und zeigt Ihnen, wie Sie alle Projekte mit dem Espruino und wenigen alltäglichen Komponenten selbst verwirklichen können.Espruino-Boards sind leicht erhältlich und der Espruino-Interpreter lässt sich auch auf vielen Standard-Boards nachinstallieren (z.B. BBC micro:bit, Raspberry Pi).Verwenden Sie Espruino mit nur wenigen gewöhnlichen Alltagsobjekten und lernen Sie:Was ist ein Mikrocontroller und wie programmiert man ihn?Die Grundlagen der JavaScript-ProgrammierungWie man einen Motor mit einem Weinkorken basteltDie Technik zur Herstellung eines eigenen StroboskopsEinfache Roboter zu bauenWie man einen niedrig auflösenden Scanner selbst konstruiertDie Grundlagen zum Bau eines funktionierenden DruckersWie bastele ich eine Digitalkamera?... und vieles mehr Biographical note: Gordon Williams ist ein Unternehmer und Erfinder aus der Gegend von Oxford. Schon als Kind schrieb er Software und spielte mit Elektronik, später studierte er Informatik an der Universität von Cambridge.Gordon hat für verschiedene Technikunternehmen gearbeitet und sich dabei auf 3DGrafik und Compilerdesign in verschiedenen Sprachen spezialisiert. Seit 2012 arbeitet er an dem JavaScript-Interpreter Espruino. Dabei hat er im Alleingang drei erfolgreiche Crowdfunding-Kampagnen gestartet und vier verschiedene Espruino-Geräte entwickelt. Inzwischen entwickelt Gordon Espruino hauptberuflich weiter und unterstützt damit eine großartige Gemeinschaft von Espruino-Benutzern in aller Welt. Des Weiteren tritt er als Redner auf Veranstaltungen zu JavaScript, eingebetteter Software und bei Maker-Communitys in aller Welt auf.

Create and animate stunning 3D browser based graphics with Three.js JavaScript library Key Features Enhance your 3D graphics with light sources, shadows, advanced materials, and textures Load models from external sources, and visualize and animate them directly from JavaScript Create your own custom WebGL shader and explore the postprocessing feature of Three.js Book Description WebGL makes it possible to create 3D graphics in the browser without having to use plugins such as Flash and Java. Programming WebGL, however, is difficult and complex. With Three.js, it is possible to create stunning 3D graphics in an intuitive manner using JavaScript, without having to learn WebGL. With this book, you'll learn how to create and animate beautiful looking 3D scenes directly in your browser-utilizing the full potential of WebGL and modern browsers. It starts with the basic concepts and building blocks used in Three.js. From there on, it will expand on these subjects using extensive examples and code samples. You will learn to create, or load, from externally created models, realistic looking 3D objects using materials and textures. You'll find out how to easily control the camera using the Three.js built-in in camera controls, which will enable you to fly or walk around the 3D scene you created. You will then use the HTML5 video and canvas elements as a material for your 3D objects and to animate your models. Finally, you will learn to use morph and skeleton-based animation, and even how to add physics, such as gravity and collision detection, to your scene. After reading this book, you'll know everything that is required to create 3D animated graphics using Three.js. What you will learn Work with the different types of materials in Three.js and see how they interact with your 3D objects and the rest of the environment Implement the different camera controls provided by Three.js to effortlessly navigate around your 3D scene Work with vertices directly to create snow, rain, and galaxy-like effects Import and animate models from external formats, such as OBJ, STL, and COLLADA Create and run animations using morph targets and bones animations Explore advanced textures on materials to create realistic looking 3D objects by using bump maps, normal maps, specular maps, and light maps Interact directly with WebGL by creating custom vertex and fragment shaders Who this book is for The ideal target audience for this book would be JavaScript developers who who wa...
