+Vite will replace `__filename`, `__dirname`, and `import.meta.url` in config files and its deps. Using these as variable names or passing as a parameter to a function with string double quote (example `console.log`) will result in an error:
 
 ```js
 const __filename = "value"
 // will be transformed to
 const "path/vite.config.js" = "value"
+
+console.log("import.meta.url") // break error on build
 ```
