Vite build tool configuration, plugin API, SSR, and Vite 8 Rolldown migration. Use when working with Vite projects, vite.config.ts, Vite plugins, or building libraries/SSR apps with Vite.
— the description by Anthony Fu

AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

This skill provides comprehensive reference material for Vite 8, a frontend build tool that utilizes the Rolldown bundler and Oxc transformer. It covers core configuration patterns, the plugin API, library mode, and SSR primitives. It also includes specific guidance for migrating to Vite 8, managing multi-environment setups, and utilizing the JavaScript API for programmatic control over build and development processes.

What it does

  • Provides patterns for vite.config.ts including conditional and asynchronous configurations.
  • Explains the Rolldown migration process for Vite 8 projects.
  • Details the Vite plugin API for creating custom hooks and virtual modules.
  • Offers guidance on library mode, SSR middleware, and multi-page application setups.
  • Documents the JavaScript API for programmatic server creation and build execution.
  • Lists official plugins for framework support including Vue and React.

When to use it

  • When configuring a new or existing Vite 8 project.
  • When migrating a project from previous Vite versions to Vite 8.
  • When building libraries or SSR applications using Vite primitives.
  • When developing custom Vite plugins or integrating multi-environment support.
  • When needing to programmatically control the Vite build or dev server via the JavaScript API.

Advantages

  • Centralized reference for Vite 8 specific changes like Rolldown and Oxc.
  • Clear examples for complex configurations like proxying and environment variables.
  • Provides structured guidance for library distribution and multi-page entry points.
  • Includes TypeScript intellisense patterns for configuration files.

Usage examples

“How do I configure a proxy in my vite.config.ts?”
The skill provides a code snippet showing the server.proxy configuration object with target, changeOrigin, and path rewrite options.
“Show me how to set up a library build in Vite 8.”
The skill provides a configuration example using the build.lib option, including entry points and rolldownOptions for external dependencies.
“How do I access environment variables inside my Vite config?”
The skill demonstrates using the loadEnv function within a defineConfig function to access variables from .env files during configuration resolution.
“What is the new way to define entry points in Vite 8?”
The skill explains the top-level input option which replaces previous entry point configurations for build, SSR, and dependency optimization.

Documentation by Anthony Fu

Vite

Based on Vite v8.3.5 (Rolldown-powered), generated at 2026-11-05. Vite 8 uses the Rolldown bundler and the Oxc transformer instead of esbuild + Rollup.

Vite is a next-generation frontend build tool with fast dev server (native ESM + HMR) and optimized production builds.

Preferences

  • Use TypeScript: prefer vite.config.ts

  • Always use ESM, avoid CommonJS
