Description

We’ve become accustomed to developing complex applications with powerful desktop and laptop machines, which only emphasizes that the mobile web is slow: 73% of mobile internet users say that they’ve encountered a website that was too slow to load. The world of frontend development is continuously evolving with more client-side heavy applications—and bundle sizes for many JavaScript frameworks can be huge. This can significantly affect loading times, especially on a mobile device with a poor connection.

Houssein Djirdeh offers an overview of the PRPL pattern, explaining what it is and how you can use it to build fast and reliable progressive single-page applications for users on any device.

Topics include:

  • How to push the most important resources first
  • How to render your initial route as soon as possible
  • How to precache resources for all your routes using a service worker
  • How to lazy load your remaining routes so that they load on demand
