Introduction
Last week I was at Vueconf US. It's one of my favorite conferences and I try to go every year. This year Evan You gave a talk on the future of Vue and tooling. Halfway through he started talking about Vite and some of the new features of Vite 8 that just came out. I was amazed at how far Vite has come and the millions of downloads a month it's getting. What I found especially interesting was how few people really knew about these features. Evan asked the audience by a show of hands who had tried out Vite 8, and only a few people raised their hands! So when I got home I decided to write this blog post and create a video on some configurations you must try out with Vite, including some new features that just came out with Vite 8.
If you haven't heard yet, Vite 8 shipped in March 2026 with the most significant architectural change since Vite 2. One of the most significant is the Rust-based bundler called Rolldown that delivers 10-30x faster builds. If you've been using Vite with zero config, that's fine. The defaults are great. However, there are a handful of options that, once you know them, you'll reach for in every project.
This post covers 8 config options that you should know. Two are new in Vite 8, and six have been around but you probably have not heard of them. All of them go in your vite.config.ts.
