    If you have been to any conference in the last five years, you have probably heard about Progressive Web Apps<\/span><\/strong> (PWA<\/strong>). Web sites<\/span> that can progressively turn into app<\/span>-like experiences and be installed on your devices<\/span>. Kenneth Rohde Christiansen is Senior Web Platform Architect at Intel<\/span> Corporation and an <\/em>elected member of the W3C<\/span> Technical Architect Group (TAG). He’s currently working on making Progressive Web Apps<\/span> more capable as part of Project Fugu<\/a>, an effort to close gaps in the web<\/span>‘s capabilities enabling new classes<\/span> of applications<\/span> to run on the web<\/span>.  I spoke with him before his presentation at Codemotion\u2019s online conference: The Italian edition<\/em><\/a> to find out more.<\/p>\n\n\n\n

    What’s the genesis of progressive web apps?  <\/h2>\n\n\n\n

    According to Christian, “For many years, people working with the web have wanted something like progressive web apps<\/span>. I used to work for Nokia, and at that point, people could write kind of native-like applications<\/span> using the web<\/span>. It was the same thing when the iPhone<\/span> came out; you had ‘Add to Home screen<\/span>‘. A lot of like people that were web developers<\/a><\/span> were also interested in also building apps<\/span> for these devices<\/span>. But they were limited in comparison to what you could do on other platforms.”<\/p>\n\n\n\n

    Himself and others working on the web<\/span> pushed the idea, “Hey, we should make this possible, the Add to Homescreen<\/em> idea is great. What do we need to really take this to the next level?”<\/p>\n\n\n\n

    Corporations focused on creating packaged apps<\/span> without standards<\/span>, which Christian felt removed some of the advantages of the web<\/span><\/strong> itself. In response, he and others created the Web app manifest<\/a>. It may look simple today but was an extensive effort. Christian recalls: “We had to figure out requirements. How do we make sure that it looks like a full-screen app<\/span> or as a standalone window of the desktop<\/span>? What about the icons? Where should you launch the app<\/span>? And we turned that into a standard.”<\/p>\n\n\n\n

    The manifest caught the interest of Google<\/span><\/strong>, where some of the developers<\/span> got so excited that they started implementing the ideas inside of Chrome<\/span> on Android<\/span>. “They saw Add to Homescreen<\/em> as really the future. At the same time, people at Google<\/span> came up with this proposal called navigation controller<\/span>: how do I interact with the network, especially if I’m offline<\/span>? Can I make an experience a web experience that will work like offline<\/span> as well, or work with an intermediate network? Mozilla<\/span> came on board and the project<\/span> was renamed Service<\/span> Worker. <\/p>\n\n\n\n

    Another standard that “allows you whenever you’re fetching a file<\/span> from a web application<\/span>, to go through a proxy<\/span> server<\/span>, that’s called ServiceWorker<\/strong>, which then can like return that from a cache, or it can get it from a different server<\/span>. It’s very flexible and allows people to create offline<\/span> experiences and those that can be considered semi offline<\/span>, with an intermittent network. That combined with the web manifest Add to Homescreen<\/em> turned into what we call progressive web apps<\/span> today.”<\/p>\n\n\n\n

    There was extensive interest from browser<\/span> vendors and companies<\/span> like Samsung for their own internet. It slowly became possible on mobile<\/a>. Christian believed that the experience should also be available in desktop<\/span>. While Google<\/span> saw it at the time of more crucial for mobile<\/span>, Microsoft<\/span> started taking an interest, due to their Edge browser<\/span>. They thought “these progressive web apps<\/span> will be great for Windows<\/span> because not everyone wants to create a Windows<\/span> app<\/span> from scratch.” Google<\/span> saw the value for Chrome OS<\/span><\/strong>, and since then, like everyone has been pushing progressive web apps<\/span>.” This included companies<\/span> that had initial success on mobile<\/span> that wanted a good desktop experience. “Combined with new API<\/span>‘s coming to the web<\/span>, you can really do all the things that you need to do like file access<\/span> – we’re developing<\/span> this new specification called file system<\/span> access, where you can access your local files<\/span> as you do in any other native app<\/span>.”<\/p>\n\n\n\n

    The challenge of upselling progressive web apps to management<\/h2>\n\n\n\n
    \"Progressive<\/figure><\/div>\n\n\n\n

    Progressive web apps<\/span> appeal to web developers<\/span><\/strong> who want “a very tightly integrated, nice experience that works on mobile<\/span> and on desktop<\/span><\/strong>. They like progressive web apps<\/span> because like it takes very little effort to get something nice. However, it’s still a lot of effort actually selling that story to your management<\/span>. Some companies<\/span> will be reluctant, claiming that most of our users<\/span> are iOS<\/span> users<\/span>. So it doesn’t really matter that we have a native app<\/span>. So that is still lagging a bit behind.” <\/p>\n\n\n\n

    Christian, however, believes that the focus on the desktop experience means we are really about to shine. <\/p>\n\n\n\n

     What’s next for progressive web apps?<\/h2>\n\n\n\n

    Christian spoke of the fast progression in development, nothing that the next big thing is even better integration<\/span> in host OSs. For example, with Microsoft<\/span>, if you go to uninstall an app<\/span>, the PWA will show up. You basically cannot tell that this is not a native app<\/span><\/strong> installed on Windows<\/span>. It’ll be in the taskbar<\/strong>. If you get a notification on the app<\/span>, it will be able to show this batch on the icon – e.g.l how many unread notifications or news articles you have in the app<\/span>. There’s jump list – If you long press on an icon or right-click on an icon you get a new message, new event, new calendar shortcuts. They’re even working on the title bar, trying to make it possible to do slight modifications, for example, getting a search bar in the title bar, you see this on Spotify<\/span>.”<\/p>\n\n\n\n

    Christian explained, “When you go to a website that is a PWA, you get a few features<\/span> you won’t get if it’s just in your browser<\/span>, because it’s installed. Being installed means that it’s kind of there on your system as an icon. That also means that you can share content to this progressive web app<\/span>. And you can even register the app<\/span> to open files<\/span> with it through the file<\/span> explorer. So this is the kind of level of integration<\/span> you will be getting with progressive web apps<\/span>.”<\/p>\n\n\n\n

    The team<\/span> is also working on the Fugu API<\/span><\/strong>: “We’re trying to make the web<\/span> more capable of having the same capabilities as any native app<\/span>, as long as it can be done in a safe way that is privacy-preserving. So progressive web apps<\/span> are part of specific progressive web technology that will become much more capable.”<\/p>\n\n\n\n
