In this minor, we focused on improving the dev server performance. The resolve logic got streamlined, improving hot paths and implementing smarter caching for finding package.json, TS config files, and resolved URL in general.
You can read a detailed walkthrough of the performance work done in this blog post by one of Vite Contributors: How we made Vite 4.3 faaaaster 🚀.
This sprint resulted in speed improvements across the board compared to Vite 4.2.
These are the performance improvements as measured by sapphi-red/performance-compare, which tests an app with 1000 React Components cold and warm dev server startup time as well as HMR times for a root and a leaf component:
