Even with the most optimized code, it is hard for eCommerce sites to reach a 100 out of 100 score on PageSpeed Insights unless they serve only static HTML. By Misko Hevery.
By removing all of the JavaScript execution we can get a perfect score of 100 and pass with flying green colors! But, therein lies the problem. These pages are static. We need our pages to deliver content dynamically, full of interaction and life. How can we serve static HTML to receive high scores, but at the same time provide rich interaction?
The reason is that all existing frameworks are not designed with time-to-interactive in mind. They have complex bootstrap processes which require a lot of code to be downloaded and executed before the page can become interactive. Yes, most support server-side-rendering to get a quick flash of initial content, but the first thing they need to do is to download all of the templates on the page and execute them to rehydrate the page and make it interactive.
Introducing Qwik, an open-source DOM-centric, resumable web-app framework designed for best possible time-to-interactive, by focusing on resumability of server-side-rendering of HTML and fine-grained lazy-loading of code. The basic goal of Qwik is to focus on the time-to-interactive metric by delaying JavaScript as much as possible to take advantage of the browser’s lazy loading capabilities.
Qwik’s goal is to crush time-to-interactive to a blink of an eye on the slowest mobile device. We want to serve static pages to the user so that they are fast, but retain all of their interactivity. We want to have our cake and eat it too! Good read!
