    Vite: Beyond a Build Tool and State of Vite 2025!

  • Mathias Biilmann

    From DX to AX: What Happens When AI Agents Build Your Vite App

    By Mathias Biilmann

    A perspective on the importance of agent experience (AX) which is proliferating fast, relevant to devs, teams, businesses alike. Keeping things practical, outlining an example of agent-built apps (couple Vite’s speed + Netlify’s MCP to create a safe, repeatable deployment routine an autonomous agent can trust)

    Rolldown: the JavaScript bundler written in Rust intended to serve as the future bundler used in Vite

    By Alexander Lichter

  • Jacob Gross

    Rolldown: Chunking in the wild

    By Jacob Gross

    How & why we started using it at Framer, how it compares to esbuild and why advanced chunking is an important feature to have, plus how Jacob helped design the chunking API and what our config looks like in a React stack. We've been running Rolldown on our homepage (www.framer.com) since half a year or so and are currently rolling out Rolldown to our stable channel. So by the time the conf is hosted I can also bring some real world experience from over 100k websites.

    tsdown: One Tool to Bundle Them All

    By Kevin Deng

    In this talk, we’ll dive into tsdown, a powerful and efficient tool designed to streamline the packaging process for TypeScript libraries. Whether you’re building Node.js modules or Vue component libraries, tsdown aims to unify and simplify your workflow. We’ll explore the core design principles behind tsdown and demonstrate how it automates type declaration generation, dependency analysis, and multi-format output. By the end of this session, you’ll see how tsdown empowers developers to publish high-quality libraries with ease and confidence.

    JS at the speed of Rust: Oxc

    By Jim Dummett

    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 Oxc is aiming 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.

    Building in Fast Feedback Loops

    By Kenneth Skovhus

    At Linear, speed shapes everything. We’ll walk through the systems that enable fast feedback loops and the challenges we’ve faced keeping it as we scale.

    Speeding up the ecosystem

    By James Garbutt

    Making Meaningful Open Source Contributions

    By Sarah Rainsberger

    Open source projects need help—but not always in the ways you think. Big features and bug fixes can actually add stress for maintainers, especially from newcomers. What many projects really need are overlooked contributions like issue triage, docs, community support, marketing, and onboarding. Using examples from the Astro community, this talk will show how you can make meaningful contributions that truly help maintainers—and how maintainers can make it easier for others to contribute effectively.

    The Vite Environment API: closing the gap between development and production

    By James Opstad

    Find out how the Cloudflare Vite plugin uses the Environment API to closely match production behaviour in development. Developers are provided with full access to platform specific features while retaining Vite’s trademark development experience. We will also look at how the Environment API enables framework and platform plugins to work together through a shared contract with Vite.

    Remote Control

    By Rich Harris

    SvelteKit's Remote Functions are a fresh take on RPC that makes type-safe client-server communication fast, easy and secure. But they weren't easy to build. This is the story of how we stretched the Vite plugin API to its limits in pursuit of the ultimate developer experience.
