Tim Vereecke – Responsive RUM – WLS 2021
Categorizing device types by desktop, mobile and tablet no longer works in 2021. It is oversimplified, meaningless and likely breaks your current performance analysis on a modern responsive website.
As #perfmatters we need meaningful monitoring that takes into account the modern web:
Screen dimensions
Device pixel ratios
Image and CSS breakpoints
Connections
Keeping it both simple and meaningful is however not easy! Learn about the different approaches and how to apply this to your existing RUM monitoring solutions: be it free (Google Analytics), open source (Boomerang) or commercial.
