Micro frontends - team management, complexity and governance challenges “As a more distributed architecture, micro frontends will inevitably lead to having more stuff to manage - more repositories, more tools, more build/deploy p… more
CSS loading optimizations like Critical CSS are often one of the main tools to optimise for the first meaningful paint metric. This directly impacts the user experience as it lets the browser paint pixels on the screen with minimum data possible.
There are multiple parts to this problem such as:
- Detecting what all markup and CSS to load.
- How to lazy load the rest of the stylsheets.
- What strategy to use to evaluate critical CSS.
- How to do this without impacting time to first byte.
This conference is curated by Prateek Bhatnagar, frontend architect at Uber. Previously, Prateek was senior software engineer (frontend), collaborating with NextJS to help push the bar of performance on web using wrapper frameworks.
- Evaluate a variety of options for improving important web vitals.
- Knowledge about tools and frameworks which are providing these optimizations out of the box.
- Awareness about popular techniques around dead code elimination.

Critical CSS for CMS-based Server Rendered Websites
A super fast website often involves inlining your critical CSS while lazy loading the non-critical CSS. You understand what that means, but you’ve got a CMS-based website with many templates and hundreds or more (server rendered) pages but no simple switch or plugin to “Turn on Critical CSS”. This talk will show you how to marry Critical CSS with a site like yours to produce webpages that load quickly and get your green scores in your performance monitors.
We’ll look at an end-to-end solution that we have evolved and battle tested over the years at Miranj. I’ll cover identifying target templates, leveraging the Critical & Penthouse libraries to extract critical CSS, automating the extraction process using Gulp, reducing response size for repeat visitors, and getting this entire system to work with the caching layer(s) that you may already be using.
