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.

Actions and Reducers

So, we have our core services and can start designing the Redux store. We can describe the intended state mutations in a table:

Action creator

Action Type

State Impact

toggleOpenAddFeed

TOGGLE_ADD_FEED

state.isOpenAddFeed

addFeed

ADD_FEED

state.isOpenAddFeed

state.feedError
state.items

setFeedError

SET_FEED_ERROR

state.feedError

removeFeed

REMOVE_FEED

state.feedError

fetchFeed

FETCH_FEED

state.items
state.feedError

fetchMenu

FETCH_MENU

state.menu
state.items

state.activeFeedUrl

setActiveFeed

SET_ACTIVE_FEED

state.activeFeedUrl

First of all, we need to populate our feed menu. For that, we are going to have a modal window with a form to add a feed. The action creator function toggleOpenAddFeed will be used to toggle the visibility of the modal window.

When the form in the modal window is submitted...
