Description: swc-loader issue? What to choose between Rollup, Vite, Webpack, Rspack and Build for applications? How to approach a migration or write a plugin to fit your needs?  After this talk the audience will understand how bundlers work, some "hacks" we can do to customise it and the differences between bundlers to future proof your applications.

In the ever-evolving landscape of web development, bundlers play a crucial role in optimizing application performance. Rspack, a Rust-based bundler, has emerged as a promising alternative to traditional tools. This presentation will delve into the intricacies of Rspack, exploring its architecture, key features, and performance advantages. By the end, you will have a solid understanding of how to harness Rspack's power to create high-performance web applications.

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.

The JavaScript ecosystem is longing for a standardized tooling. No more plumbing work, no more choice fatigue and no more analysis paralysis. But how would such a tool look like? Together, we have a look at the newly released Vite+ Alpha and see if the new open source CLI can hold up to its promises, covering developer's tooling needs and let them focus on shipping, especially in an agentic age.
