TypeScript: Modern JavaScript Development

Book Description

Leverage the features of TypeScript to boost your development skills and create captivating applications

About This Book

• Learn how to develop modular, scalable, maintainable, and adaptable web applications by taking advantage of TypeScript
• Explore techniques to use TypeScript alongside other leading tools such as Angular 2, React, and Node.js

Who This Book Is For

This Learning Path is for intermediate-level JavaScript developers who want to use TypeScript to build beautiful web applications and fun projects. No prior knowledge of TypeScript is required, but a basic understanding of jQuery is expected. This Learning Path is also for experienced TypeScript developers who want to take their skills to the next level, and also for web developers who wish to make the most of TypeScript.

What You Will Learn

• Understand the key TypeScript language features and runtime
• Install and configure the necessary tools in order to start developing an application
• Create object-oriented code that adheres to the SOLID principles
• Develop robust applications with testing (Mocha, Chai, and SinonJS)
• Apply GoF patterns in an application with a testing approach
• Identify the challenges when developing an application
• Migrate JavaScript codebases to TypeScript to improve your workflow
• Utilize System.JS and Webpack to load scripts and their dependencies
• Develop high performance server-side applications to run within Node.js

In Detail

TypeScript is an open source and cross-platform typed superset of JavaScript that compiles to plain JavaScript that runs in any browser or any host. TypeScript adds optional static types, classes, and modules to JavaScript, to enable great tooling and better structuring of large JavaScript applications. Through this three-module learning path, you’ll learn the ins-and-outs of TypeScript for building more robust software.

The first module gets you started with TypeScript and helps you understand the basics of TypeScript and automation tools. Get a detailed description of function, generics, callbacks, and promises, and discover the object-oriented features and memory management functionality of TypeScript.

The next module starts by explaining the current challenges when designing and developing an application and how you can solve these challenges by applying the correct design pattern and best practices. You will be introduced to low-level programming concepts to help you write TypeScript code, as well as working with software architecture, best practices, and design aspects.

The final module will help you build a complete single page app with Angular 2, create a neat mobile app using NativeScript, and even build a Pac Man game with TypeScript. As if the fun wasn’t enough, you’ll also find out how to migrate your legacy codebase from JavaScript to TypeScript.

By the end of this Learning Path, you will be able to take your skills up a notch and develop full-fledged web applications using the latest features of the TypeScript.

This Learning Path combines some of the best that Packt has to offer in one complete, curated package. It includes content from the following Packt products:

About This Book

• 了解如何利用TypeScrip开发模块化、可伸缩、可维护和适应性强的Web应用程序
• Explore techniques to use TypeScript alongside other leading tools such as Angular 2, React, and Node.js
• 本分步指南侧重于打字稿中的设计模式，演示了实践中所有重要的设计模式

这本书是为谁写的

本学习路径面向那些想要使用TypeScrip构建漂亮的Web应用程序和有趣的项目的中级JavaScript开发人员。不需要事先了解类型脚本，但需要对jQuery有基本的了解。这条学习途径也适用于想要将自己的技能提升到更高水平的有经验的打印脚本开发人员，以及希望充分利用打印脚本的Web开发人员。

你将学到什么

• Understand the key TypeScript language features and runtime
• Install and configure the necessary tools in order to start developing an application
• 创建遵循可靠原则的面向对象代码
• 通过测试(Mocha、Chai和SinonJS)开发健壮的应用程序
• 使用测试方法在应用程序中应用GoF模式
• 确定开发应用程序时面临的挑战
• Migrate JavaScript codebases to TypeScript to improve your workflow
• Utilize System.JS and Webpack to load scripts and their dependencies
• Develop high performance server-side applications to run within Node.js

In Detail

TypeScrip是一个开源的跨平台类型的JavaScript超集，它可以编译成在任何浏览器或任何主机上运行的纯JavaScript。TypeScrip将可选的静态类型、类和模块添加到JavaScript中，以支持强大的工具和大型JavaScript应用程序的更好结构。通过这三个模块的学习，您将学习构建更健壮的软件的打字脚本的细节。

第一个模块让您开始使用TypeScrip，并帮助您了解TypeScrip和自动化工具的基础知识。获取函数、泛型、回调和承诺的详细描述，并了解TypeScrip的面向对象特性和内存管理功能。

下一个模块首先解释设计和开发应用程序时面临的当前挑战，以及如何通过应用正确的设计模式和最佳实践来解决这些挑战。将向您介绍低级编程概念，以帮助您编写打字脚本代码，以及使用软件体系结构、最佳实践和设计方面。

最后一个模块将帮助您构建一个完整的单页应用程序与角度2，创建一个整洁的移动应用程序使用NativeScrip，甚至建立一个吃豆人游戏与文字。如果乐趣还不够，您还将了解如何将遗留的代码库从JavaScript移植到TypeScrip。

在本学习路径结束时，您将能够将您的技能提升一个档次，并使用打字稿的最新功能开发成熟的Web应用程序。
