Progressive Web Apps

Starbucks and Ipsy Win with eCommerce PWA and SPA Frontends

Progressive Web Apps have become the fastest, most reliable and engaging frontend, particularly on mobile. See how Starbucks and others win with modern technology.

Progressive Web Apps (PWAs) have become the fastest, most reliable and engaging frontend, particularly on the mobile-web. Network performance has become a concern of the past, as service workers allow PWAs to deliver speedy page loads regardless of network quality. This modern web technology along with others, including Single Page Applications (SPAs), and Accelerated Mobile Pages (AMP), change the game for eCommerce websites, enhancing the entire digital experience from landing through checkout.

If you run an online business, you know performance is crucial. Slow sites have a negative impact on search ranking, traffic, conversions, and revenue. Even the almighty Amazon calculated a $1.6 billion drop in annual sales, with a one-second delay in page load. The eCommerce industry is realizing the need to provide the best, and fastest, mobile experience  with leaders like Nike, Walmart, Target, and, going headless with PWAs and AMP. But if you haven’t already figured that out, we have you covered.

We’ve been showcasing examples of top eCommerce PWAs on a monthly basis. These are examples of industry leaders who’ve made the shift to headless eCommerce architecture and adopted PWAs and/or SPA frontends, along with other cutting-edge technologies. Those who have made the switch see dramatic business wins and appreciation from today’s consumers who demand site speed.
