Progressive Web App (PWA), in general, is a term used to denote web apps that use the latest web technologies. As such, this year’s PWAs will be average web apps in a few years.

Specifically, though, Progressive Web Apps, also known as Installable Web Apps or Hybrid Web Apps, are regular web pages (or websites) but can appear to the user like traditional applications or (native) mobile applications. This new application type attempts to combine features offered by most modern browsers with the benefits of mobile experience. This specific use of the term is the subject of this article.

Another fresh and hot video from Google Developers Day Europe 2017. In this video, you'll learn where to start with Progressive Web Apps, what to implement, and how to prioritize PWA techniques. You'll also learn how to make the most of 'low hanging fruit' and take advantage of small changes that can have a big impact.

Electron 8.0.0 to be Released

The new released is considered major due to the upgrade to the Chromium 80 code base, the Node.js 12.13 platform, and the V8 8.0 engine
06 February 2020   139

The release of the Electron 8.0.0 platform has been prepared, which provides a self-sufficient framework for developing multi-platform user applications, using Chromium, V8 and Node.js. components as a basis. A significant change in the version number is associated with the upgrade to the Chromium 80 code base, the Node.js 12.13 platform, and the V8 8.0 JavaScript engine.

Among the Electron-specific API changes:

  • Provided the ability to check spelling in input forms using the built-in Chrome spellchecker;
  • When exchanging data between processes (IPC), the Structured Clone Algorithm, which is used in the V8 engine to copy complex JavaScript objects, is used. Compared to the previously used data serialization mechanism, the new algorithm is more predictable, fast and functional. When moving large buffers and complex objects, the new algorithm is approximately two times faster with practically unchanged delays in the transmission of small messages;
  • Disabled rendering to the buffer (Offscreen Rendering) is disabled, because when switching to a new release of Chromium there were problems, and the subsystem was left without an accompanying one;
  • New APIs added: app.getApplicationNameForProtocol (url), BrowserWindow.getMediaSourceId (), BrowserWindow.moveAbove (mediaSourceId), session.downloadURL (url), session.addWordToSpellCheckerDictionary, tray.removeBallexava () (worldId, scripts [, userGesture]).

Electron allows you to create any graphical application using browser technology, the logic of which is determined by JavaScript, HTML and CSS, and the functionality can be expanded through the add-on system. Node.js modules are available for developers, as well as an advanced API for creating native dialogs, integrating applications, creating context menus, integrating with the notification output system, window manipulation, and interaction with Chromium subsystems.

Unlike web applications, Electron-based programs come in the form of self-contained executable files that are not browser-bound. In this case, the developer does not need to worry about porting the application for various platforms, Electron will provide the ability to build for all systems supported in Chromium. Electron also provides tools for organizing the automatic delivery and installation of updates (updates can be delivered either from a separate server or directly from GitHub).

Among the programs built on the basis of the Electron platform, one can mention the Atom editor, the Nylas email client, the tools for working with Git GitKraken, the Wagon analysis and visualization system for SQL queries, the WordPress Desktop blogging system, the WebTorrent Desktop BitTorrent client, as well as the official clients for Services like Skype, Signal, Slack, Basecamp, Twitch, Ghost, Wire, Wrike, Visual Studio Code and Discord. In total, about 850 applications are presented in the Electron software catalog. To simplify the development of new applications, a set of standard demo applications has been prepared, including code examples for solving various problems.
