Chrome Web Store was originally launched in 2010 and serves as a hub for installing apps, extensions and bundled themes for Chrome. More than a year ago, Google announced that it would phase out Chrome apps on Windows, Mac and Linux in 2018. Today, the company sent an email to developers with additional information, as well as news about future Progressive Web App support.  The existing schedule continues for the most part: Chrome apps in the web store will no longer be detectable for Mac, Windows and Linux users. In fact, if you visit the store at this time on anything other than a Chromebook, the apps page is no longer there. Originally, Google planned to eliminate application support on all platforms (except the Chrome operating system) in the first quarter of 201
The Chrome team is now working to allow progressive web applications (PWA) installed on the desktop. Once this functionality is sent (approximately mid-2018), users will be able to install web applications on the desktop and execute them through icons and shortcuts; Similar to the way Chrome apps can be installed today.
To allow a smoother transition from Chrome applications to the web, Chrome will not completely eliminate compatibility with Chrome applications on Windows, Mac or Linux until after the installation of Desktop PWA will be available in 2018. The lines of time are still difficult, but this will be a number of months later than the originally planned disapproval timeline of "early 2018".
We also recognize that desktop PWAs will not replace all the capabilities of Chrome applications. We've been researching ways to simplify the transition for developers who rely on Chrome's unique application APIs, and we'll continue to focus on this, particularly the Sockets, HID and Serial APIs.
Progressive Web applications and Chrome applications are designed to make web applications more responsive to native desktop applications, but the similarities end there. PWAs are cross-platform and cross browser, while Chrome apps are obviously limited to Google's browser and use proprietary Chrome APIs.
Chrome on Android already supports the installation of PWA, even giving them their own icon in the drawer of the application. It will be interesting how Google provides the same treatment to Windows, Mac and Linux.
