Cross-platform Desktop Application Development: Electron, Node, NW.js, and React

Overview of this book

Building and maintaining cross-platform desktop applications with native languages isn’t a trivial task. Since it’s hard to simulate on a foreign platform, packaging and distribution can be quite platform-specific and testing cross-platform apps is pretty complicated.In such scenarios, web technologies such as HTML5 and JavaScript can be your lifesaver. HTML5 desktop applications can be distributed across different platforms (Window, MacOS, and Linux) without any modifications to the code. The book starts with a walk-through on building a simple file explorer from scratch powered by NW.JS. So you will practice the most exciting features of bleeding edge CSS and JavaScript. In addition you will learn to use the desktop environment integration API, source code protection, packaging, and auto-updating with NW.JS. As the second application you will build a chat-system example implemented with Electron and React. While developing the chat app, you will get Photonkit. Next, you will create a screen capturer with NW.JS, React, and Redux. Finally, you will examine an RSS-reader built with TypeScript, React, Redux, and Electron. Generic UI components will be reused from the React MDL library. By the end of the book, you will have built four desktop apps. You will have covered everything from planning, designing, and development to the enhancement, testing, and delivery of these apps.

Application blueprint

This time, we will develop a screen capturer, a little tool capable of taking screenshots and recording screencasts.

The core idea can be expressed with the following user stories:

  • As a user, I can take a screenshot and save it as a .png file
  • As a user, I can start recording a screencast
  • As a user, I can start recording the screencast and save it as .webm file

Additionally, I expect a notification to appear when a screenshot or screencast file is saved. I also would like to have the application presented in the system notification area (Tray) and to respond to specified global hot-keys. With a help of WireframeSketcher (http://wireframesketcher.com/), I illustrated my vision with the following wireframe:

The wireframe implies a Tabbed Document Interface (TDI) with two panels. The first one, labeled as Screenshot, allows us to take a screenshot (photo...
