Bringing the JAMstack to the Enterprise

This document provides an overview of service workers and how they can be used. It begins with registering a service worker script and discussing the install and activate lifecycle events. It then covers using service workers to handle fetch events to provide offline functionality by precaching resources and serving cached responses when offline. Finally, it discusses several other potential uses of service workers like custom error pages, CDN failover, prefetching, and metrics collection.

Understanding what happens on the client side is not easy. When you user visits your website you need to check his location, his device, connection speed, browser, and what page he is visiting. After gathering all this data, you also need to check what happened. How long it takes for him to see the page? How long it takes until the page is fully loaded and working? If there was a JS error what was it and why can’t you replicate it? Most of the users don’t have powerful machines, with fast-connections. In this talk we will analyze the tools you can use to profile the client, synthetic and RUM analysis and how you can improve the performance on the client side. Basic and more advanced tips with real examples.

This document provides tips for optimizing a Joomla site for speed. It recommends keeping Joomla updated, choosing extensions wisely, simplifying templates, enabling compression, caching plugins and .htaccess rules. Specific extensions like JCH Optimize are suggested for combining and minifying CSS/JS and images. Server-level optimizations include using a CDN, opcode caching, moving PHP to RAM, and reverse proxy caching. Testing speed with tools like Google PageSpeed Insights is advised. Application optimizations alone can improve page load times from over 5 seconds to 3 seconds, while full server optimizations achieve over 1 second load times.

This document discusses techniques for improving perceived performance of websites. It explains that perceived performance is how quickly a site seems to load from a user's perspective, rather than actual technical performance metrics. Some key techniques discussed include using skeleton screens, progressive enhancement, and showing loading progress to trick users into thinking a site is loading faster than it actually is. The document also advocates for measuring real user performance data through APIs to identify actual bottlenecks and prioritize improvements.
