Chrome Dev Summit 2016: The Mobile Web Moves Forward
2016年11月16日水曜日
Last week at the 4th annual
Chrome Dev Summit
, we were excited to share a glimpse of what’s possible with
over 1,000 developers in person, and thousands more on the livestream. Each year this is a time to hear what developers have been building, share our vision for the future of the web platform, and celebrate
what we love
about the web...
Reach of the web
As we've talked about before, one of the superpowers of the web is its incredible reach. There are now more than two billion active Chrome browsers worldwide, with many more web users across other browsers. The majority of these users are now on mobile devices, bringing new opportunities for us to explore as an industry.
Mobile browsers also lead the way for the internet’s newest users. Exclusively accessing the internet from mobile devices, users in emerging markets struggle with limited computing power, unreliable networks, and expensive data. For these users, native apps can be a poor match due to their large data and storage requirements. And, it’s these constraints that have resulted in the developing markets leading the charge when it comes to innovating on the web.
Progressive
Instead, the web can fill these needs for all users through an experience we've been calling
Progressive Web Apps
(PWAs). These web apps provide the performance
users
have come to expect from their device, while also offering critical capabilities such as offlining, add-to-homescreen, and push notifications. We've been encouraged by the strong adoption of these capabilities, with push notifications recently exceeding 18 billion notifications per day across 50,000 domains.
Last year when we spoke about PWAs, things were just getting started. Now we're seeing the movement in full swing, with many large sites across the globe launching great new apps and feeling the success that PWAs can bring.
Alibaba.com, built a PWA and saw a
76% increase in conversion rates
across browsers.
The investment in the mobile web increased monthly active user rates on iOS by 14 percent. On Android devices where re-engagement capabilities like push notifications and Add to Homescreen were enabled, active user rates increased by 30 percent.
Another great example is The Weather Channel. Since launching a PWA they achieved an
80% reduction in load time
and within three months, saw almost 1 million users opt in to receive web push notifications.
During the Summit, we also
heard from Lyft
, who shared their experience of building a PWA in less than a month, and using less than a quarter of the engineering support needed to build their native app.
Learn more
about our how partners are using PWA technologies to enhance their mobile web experience.
What can you do?
We also have a variety of tools, libraries, and APIs available to help you bring the benefits of PWAs to your site. For example,
Chrome's DevTools
provides assistance along every step of the development flow. DevTools has a ton of new features to help you build great mobile apps, such as network simulation, CPU throttling, and a PWA audit tool powered by
Lighthouse
.
For developers just beginning their web app or looking to rework an existing one, the
Polymer App Toolbox
provides a set of components and tools for easily building a Progressive Web App using web components. And Polymer 2.0 is right around the corner, making it easy to take advantage of the new Web Components v1 APIs shipping cross-browser and build mobile web apps with minimal overhead.
Finally, checkout can be a complicated process to complete and in the retail sector alone there are
66% fewer conversions
on mobile than on desktop.
With
PaymentRequest
, you can now bring a seamless checkout experience to your website with support for both credit cards and
Android Pay
, increasing odds for conversion.
Catch up
Finally, if you didn’t catch our live stream in real time, you can always check back on our YouTube channel for all
the recordings

Thanks for coming, thanks for watching, and most of all, thank you for developing for the web!
