Hands On: Beta PWA Support in Chrome OS

I recently discussed how Google is following Microsoft in supporting Progressive Web Apps (PWAs) on the desktop, in this case in Chrome OS. Here’s an early peek at how this works.

The PWA support I’m describing here will be coming to Chrome officially in one of the upcoming releases. But you can access it now if you’re running a Canary or Dev channel build. So you’ll need to switch from the normal Stable channel.

My Acer Chromebook 14 for Work is already configured for the Dev channel so I can check out new features early. But if you have a Chromebook and would like to check this out too, open Settings and navigate to About Chrome OS > Detailed build information > Channel and make the change.

Next, you have to enable the Desktop PWAs flag in Chrome Flags. To do that, navigate to chrome://flags in a browser window and then search forPWAs. Find the Desktop PWAs flag in the results, enable it, and then restart the browser as prompted.

OK, let’s find some PWAs. This is a bit difficult in Chrome OS since they aren’t integrated with an app store. So I did a Google search and came up with a couple of options that aren’t Twitter Lite. (Since I already am using that and it’s one of the only well-known examples of a PWA.)

First up: Starbucks, which is available at app.starbucks.com. After loading the site and signing in, I selected “Add to shelf…” from the Chrome menu. (This is unique to Chrome OS. If you’re using Chrome on Windows, you can choose More tools > Save page as” to add the site to your list of Chrome apps and create a shortcut that can be pinned to the taskbar.)

Now, when you launch Starbucks, it looks and works like a native app: It has its own shortcut in the Chrome launcher (like the Windows Start menu) and in the taskbar. And the app window takes on the color scheme of the site, in this case, green.

Unlike pinned Chrome websites (in Windows or Chrome OS), this app window also provides a basic menu of options that are available via a widget next to the minimize, restore, and maximize buttons. This menu lets you perform some useful actions like set a zoom size that is unique to this app. The app info option lets you manage the app: You can unpin it from the shelf (taskbar) or remove it from Chrome entirely.

Google Maps is also available as a PWA, though as Kenneth Christiansen explains, you have to use a specific URL (maps.google.com?force=pwa) and the browser’s developer tools (Toggle device toolbar > Application > Service Workers, and then enable both “Update on reload” and “Bypass for network”) for this to work properly right now. (Remember, this is early days.)

Once you get through all that, you can add this PWA to the shelf too. And then configure the shortcut to open as a window (and not as a tab). Voila: A blue color scheme and that app menu widget are present.

So, this is exciting stuff. And an interesting look at how PWAs should look and work on Windows 10, too, I think. Of course, the even bigger deal there is Store support, and the fact that most people won’t even know that they’re using web apps. All they’ll know is that the app selection suddenly got a lot better.

It’s going to be a great year for apps.

    <p>I just did the Starbucks PWA , using Windows 10 and the Chrome browser….. without doing any of those instructions. I just logged into my Starbucks account on their site and I got exactly what Paul got. What am I missing here?</p>

        <blockquote><a href="#247769"><em>In reply to RamblingGeek:</em></a></blockquote><p>I expect that it would work on Windows but I was asking if it would be added to the Windows Store? I believe the developer has to give Microsoft permission to be added to the store. Probably not a huge deal since I'd expect it to work no matter what but would make discover-ability better and could come into play down the road with Andromeda and would also help with the perception of the store. </p>

          <blockquote><a href="#247781"><em>In reply to Sprtfan:</em></a></blockquote><p>Nope. Microsoft can actually simply add it to the Store. No developer intervention required. TBH I doubt the developers would care at all if their PWA was added. </p>

The only thing that would matter to users is if the product worked indentically on all systems (although some users would still want it to have an OS-specific style). You don't need one code base to achieve that. The realtiy is the only time anyone gets close to a true cross-platform app is when they eliminate anything that can't be supported on all systems. That means the app isn't the best it could be on some systems.</p>

Web apps certainly don't. Is there even an industry standard for PWA apps? How can you make absolute statements about the characteristics of an approach that may vary from company to company?</p>

It's like someone saying chrome will support viewing JPG files while Edge will only support .bmp files.

    <p>I noticed something interesting. Google may be planning to market this as a more "appy" version of the existing Lite mode. In the PWA (in both Chrome and Edge), Google claims you are in Lite mode at the very bottom of the left nav menu. So I clicked it and it took me to the Help page for Lite mode. Then I clicked the Lite link in the Help page, and Lite is nearly the same as the PWA, but without the round icons, but it has the same simplified menu as the PWA.</p><p>Lite mode Help page</p><p><a href="https://support.google.com/maps/answer/3031966?p=litemode&amp;hl=en&amp;visit_id=1-636549087616297045-3449246714&amp;rd=1&quot; target="_blank">https://support.google.com/maps/answer/3031966?p=litemode&amp;hl=en&amp;visit_id=1-636549087616297045-3449246714&amp;rd=1</a></p&gt;

    <p>PWAs are simply the future of computing, for both personal and the enterprise. I'm in the midst of rolling out three major app upgrade projects, all of which are web apps replacing desktops clients. When this is done I will have ZERO internally supported clients with desktop apps. The biggest challenge is getting the user onto the damn apps, and PWAs solve a lot of these issues for me. The neat part is, users don't know the difference (they're not tech savvy), and I get to have mobile counterparts to accompany these apps. It's a win-win. I glad to see this starting to take flight in personal computing, and glad to see Google embracing them, it can only help bolster Chromebooks. </p><p>But this is BAD for Apple :)</p>

Another is to be able to translate linux sys commands natively.

    <p>In Chrome on Windows, <span style="color: rgb(0, 0, 0); background-color: transparent;">"More Tools-&gt;Save As…" saves the html to the desktop. What you want is</span> "Add to desktop…". This works with the Starbucks PWA. However I wasn't able to get the <a href="https://maps.google.com/?force=pwa&quot; target="_blank">maps.google.com/?force=pwa</a> to work for me in Windows with Chrome. I could add it to the desktop, but when I click on the "Google Maps" link on the desktop, it launches in Chrome in a tab. Starbucks, on the other hand, launched like an app (that is, no tabs) using the same procedure.</p>
