Filip Rakowski presented this talk at Vue.js Live 2023 in London: "These days web performance is one of the most important things everyone wants to optimize on their apps, and it's clear to everyone how dramatic the impact of a poorly optimized website is on business.

If you’re one of those people thinking that good performance equals a good Lighthouse score, you’ve also fallen into this trap and this talk is for you." Ready to master Vue.js?
