Join us for an engaging and insightful journey of transitioning a legacy web application with over 1 million users in the finance industry from Webpack to Vite. Discover the steps, challenges, and surprising moments that made this migration both an adventure and a valuable learning experience — including updating Node versions, modernizing npm packages, and unifying a custom homemade design system with a blend of SCSS and Tailwind.

If you write JS or TS, probably every tool you use daily is currently being rewritten in Rust.

This has advantages (have you heard that Rust is "blazing fast"?), but also potential downsides.

The evolution of JS from the dark days before async/await was fuelled by tooling written in JS. If our tools migrate to a language we don't know, will we lose the ability to control or customize them?

In this talk, I'll explain how in Oxc (the compiler underlying the next generation of the open source Vite bundler), we're trying to "square the circle" - providing rich customisation via plugins written in JS, but maintaining the exceptional performance of Rust - and take you into the nerdy details of memory layouts, allocators, garbage collection, and the tricks that make it possible to have our Rusty cake and eat it with a JS fork.

Providing a robust and unobtrusive Dev Experience to work in a monorepo is a challenging endeavour. Many teams experience resistance with monorepos due to the lack of solid tech to support it at scale.

This talk will showcase how Nx can truly make working with monorepos a joyful reality that combines a higher built-in quality with a higher productivity as well.
