-You should return a default export with object containing `code` or `data` property:

-```ts
-import {
-  CompileTimeFunctionArgs,
-  CompileTimeFunctionResult,
-} from "vite-plugin-compile-time"
-
-export default async (
-  args: CompileTimeFunctionArgs,
-): CompileTimeFunctionResult => {

-    },
-    // Trigger rebuild when watched files change
-    watchFiles: ["/absolute/path"],
-  }
-}
-```
+## Caveats
 
-See the type docs on [paka.dev](https://paka.dev/npm/vite-plugin-compile-time#module-index-export-CompileTimeFunction).
+The files where you call `compileTime` will be evaluated at build time in Node.js environment, which means you should avoid calling browser APIs on the top level. It's recommended to use `compileTime` in a separate file and import it in your app.
