I've yet to find specifics, but does anyone know if google's page speed score account for the fact that your app may be a single page application(SPA)? This could in theory change the results of the scores
// per google
Page Speed Insights measures the performance of a page for mobile devices and desktop devices. It fetches the url twice, once with a mobile user-agent, and once with a desktop-user agent.
From my understanding, the score used to only account server side rendered pages.. what about SPAs? do the scores reflect a SPA influenced web application?
