Vite Config Validator

Validate Vite configuration files exported as JSON for structural correctness, build settings, server configuration, resolve/CSS options, plugin hygiene, and best practices. Uses pure Python 3 stdlib (json, argparse, re, os, sys) -- no external dependencies.

Since Vite configs are JS/TS (vite.config.ts), the validator works with JSON-exported snapshots. Export your config first:

node -e "import('./vite.config.ts').then(m => console.log(JSON.stringify(m.default)))" > vite.config.json

Then validate the JSON output.
