Chapter 3. Building for the Mobile Web
The success of any mobile web application relies on two factors: design and performance. For mobile app design, we must have a consistent look and feel across all platforms. For better performance, we must have offline capabilities, animations on the UI, and backend services that retrieve and send data via RESTful or WebSocket endpoints. To put it simply, your app is constrained by two ever-changing speeds: the speed of the device CPU/GPU and the speed of the Internet. The UI is handled by device hardware, such as the GPU, when doing native-like animations and transitions through CSS, and your backend services are limited to the current Internet connection speed of the mobile device.
In this chapter, we’ll discuss how to design, create, and tune your mobile web app to be better looking and more performant. The chapter starts with a brief explanation of how apps should look for mobile devices then jumps into a low-level explanation of hardware-accelerated CSS and how to debug it. From there, you’ll learn what it takes to build an offline mobile application and how to bring all the code together into one application to create a native-like mobile web app that is capable of handling intermittent Internet connections. Lastly, you’ll examine today’s most popular mobile frameworks to get an understanding of when or if you should add a community-supported framework to your project.
