Css and JS are the two main blocking elements when it comes to critical rendering path. Today’s modern apps are mostly on React or other SPA’s frameworks which make it difficult to maintain the asset loading pipeline and track the page load metrics.
The talk would be cover different ways of improving the first paint time, removing parse blocking JS from the page maintaining multiple JS on the pages and execution order, the pre-connect, pre-fetch meta tags for managing assets and connections, and chunking of the response from the server for the faster download.
The talk introduces PWA@Housing.com and how caching strategies and service workers help improve the page speed and better UX helps improve the percieved speed. The talk is inpired by the efforts that went into revamping Housing.com’s mobile website and making it stand at best in almost all known metrics possible.
