Mastering PhoneGap Mobile Application Development

Chapter 2. ECMAScript 2015 and Browserify

JavaScript has quickly become the lingua franca of the Web and the language's syntax and semantics have long been in need of improvements. ECMAScript 2015 introduces a lot of syntactic sugar that makes writing JavaScript easier. It also provides many new useful concepts that simplify application development. We briefly introduced you to ES2015 in the previous chapter. We'll be delving deeper into ES2015, as it's important that you become familiar with what the new syntax looks like.

Furthermore, it can be extremely useful to reuse your own work and that of others as well. But doing so would require you to manage your dependencies and ensure that the appropriate libraries are included. Doing this manually can be painful; but you can leverage a tool such as Browserify to assist. Browserify is a utility that not only packages your JavaScript files along with their dependencies, but also provides a Node.js-like environment for...

Getting started

Several of the snippets in this chapter are also available using the interactive snippet playground that accompanies the code package of this book. Instructions to launch the playground are in the README.md file in the code package. Once it starts, select 2: ES2015 and Browerify and then browse and experiment with the examples in the adjacent dropdown. Where applicable, each section and snippet will indicate which example you should select.

Benefits of ES2015

Although we briefly touched upon ES2015 (ECMAScript 2015) in the previous chapter, it's possible that you may not be very familiar with it. Most browsers (especially mobile) do have full support for ES2015, if any at all. This is unfortunate, because there are tremendous improvements in syntax and semantics that make it easier to create complex mobile applications.

Thankfully, as you saw in the previous chapter, there are tools that port this functionality back to ES5, which is very well supported in modern browsers. These tools convert the ES2015 syntax and semantics into their ES5 equivalent (where possible). Where a perfect equivalence is not possible, the conversion will get as close as possible, which will still bring us great benefit.

We can't go over every new change in ES2015 in this book; but we do need to go over some common examples, especially if you aren't familiar with the syntax.

Note

If you are developing for older devices, you will want to...

Using Browserify

Very few applications require completely custom code. Most applications can benefit from modularization and code reuse, and it's important to use modularization to your benefit so that you can build apps more efficiently.

There's a syndrome common to many developers (and even some companies): the not-invented-here syndrome. The afflicted developer (or company) is extremely hesitant to use code, algorithms, or any other assets that they themselves didn't create. It's easy to see where this syndrome comes from—it ensures that one can't be held liable for third-party code, one can't be sued for improperly licensing assets, and so on; but it also means that one must continually reinvent the wheel. This invariably results in buggier, less secure algorithms, as everyone is always attempting to build their apps completely from scratch.

If you've worked through other books on mobile application development, chances are you've already...

Summary

We've covered quite a bit in this chapter—most of it is related to the new syntax and features that ES2015 is bringing. Furthermore, we covered how to import npm modules and utilize them in our own code.

In the next chapter, we'll work on building modular CSS files with Sass. We'll also see how to integrate this into our build process.

Key benefits

  • Create a useful PhoneGap workflow for larger projects in order to simplify and manage the development process
  • Use third-party plugins, IndexedDB, and SQLite for PhoneGap to develop large-scale, data-driven, and highly accessible applications
  • A pragmatic guide to construct top-notch large-scale applications using PhoneGap

Description

PhoneGap is a useful and flexible tool that enables you to create complex hybrid applications for mobile platforms. In addition to the core technology, there is a large and vibrant community that creates third-party plugins that can take your app to the next level. This book will guide you through the process of creating a complex data-driven hybrid mobile application using PhoneGap, web technologies, and third-party plugins. A good foundation is critical, so you will learn how to create a useful workflow to make development easier. From there, the next version of JavaScript (ES6) and the CSS pre-processor SASS are introduced as a way to simplify creating the look of the mobile application. Responsive design techniques are also covered, including the flexbox layout module. As many apps are data-driven, you'll build an application throughout the course of the book that relies upon IndexedDB and SQLite. You'll also download additional content and address how to handle in-app purchases. Furthermore, you’ll build your own customized plugins for your particular use case. When the app is complete, the book will guide you through the steps necessary to submit your app to the Google Play and Apple iTunes stores.

Who is this book for?

If you have created simple applications using PhoneGap in the past and now want to take your workflow and apps to the next level, this book will help you reach your goals. You should have a good working knowledge of HTML, CSS, and JavaScript, and prior experience with PhoneGap.

What you will learn

  • Construct build workflows that simplify complex application development
  • Integrate the next version of JavaScript to simplify your code
  • Create accessible hybrid applications
  • Persist and query data using third-party database plugins
  • Create your own PhoneGap plugins for your unique use cases
  • Create icons and splash screens suitable for submission to app stores
  • Publish your app to the Google Play and Apple iTunes stores

As an enterprise PhoneGap developer, I was happy to find this book. It covers topics like Hybrid App Accessibility, testing (including Appium), in-device databases, and some topics on deployment that are difficult to find anywhere else. The other topics, such as automating the build were helpful too. If you want to step up your PhoneGap game, this is a good book.I bought the kindle version, and the presentation was quite readable. The text is well written and most topics include code samples and diagrams, as well as installation instructions for node modules and PhoneGap plugins.

Can I download the code files for Early Access titles? Chevron down icon Chevron up icon

We try to ensure that all books in Early Access have code available to use, download, and fork on GitHub. This helps us be more agile in the development of the book, and helps keep the often changing code base of new versions and new technologies as up to date as possible. Unfortunately, however, there will be rare cases when it is not possible for us to have downloadable code samples available until publication.

When we publish the book, the code files will also be available to download from the Packt website.

How accurate is the publication date? Chevron down icon Chevron up icon

The publication date is as accurate as we can be at any point in the project. Unfortunately, delays can happen. Often those delays are out of our control, such as changes to the technology code base or delays in the tech release. We do our best to give you an accurate estimate of the publication date at any given time, and as more chapters are delivered, the more accurate the delivery date will become.

How will I know when new chapters are ready? Chevron down icon Chevron up icon

We'll let you know every time there has been an update to a course that you've bought in Early Access.
