Modern JavaScript Web Development Cookbook

By: Federico Kereki

Overview of this book

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.

Working with modules

In the Organizing code in modules section of Chapter 2, Using JavaScript Modern Features, we saw how modern JS works with modules. However, with Node, we have a little setback: it doesn't do modules the modern JS way—unless you are willing to work with experimental features!

Why doesn't Node work with the modern JS modules? The reason harkens back to several years before the new modules with import and export statements existed, and Node implemented the CommonJS module format. (We'll be seeing more about those modules in the next section.) Obviously, libraries meant to be used with Node were also developed using that format, and nowadays there are an uncountable number of modules that follow those guidelines.

However, since the new standard for modules appeared, a pressure began to apply to use the new syntax—but that posed some...
