About
Henri is a developer who turned his interests to a passionate mix of site performance engineering, pinches of user experience and what is best known as the platform. He can also be found contributing back to the community as he presides over leading a few modern development meetups, helping curate community events or volunteering his time for lunch and learns with an emphasis on literacy. This led to him launching a little *start-up* he's calling command-h.. When not reading the deluge of daily research docs and case studies, streaming, or profiling sites in his favourite tool, Henri can be found focusing training and running the fastest 5k possible (surprise surprise), encouraging a healthy lifestyle and sharing it all via #devsWhoRun.
DevTools & The Performance Tab
“Firebug basically exists for two reasons: one is to show what's going on on your page when it loads, the other is to show you what happens after the page loads”. Firebug, the original devtools, was seen as a big step in website debugging. In fact, it was called "web development evolved". The evolution of the web eventually required an evolution in debugging and ultimately, advancements in browser devtools. We moved from the ability to observe what happens during, and after a page load, to determining user experience as well as render blocking interactions.
“DevTools & The Performance Tab” is a presentation about how browser devtools provide a powerful ability to debug, specifically with web performance in mind.
