Bun provides a handful of module-specific utilities on the [`import.meta`](/docs/runtime/module-resolution#import-meta) object. Use `import.meta.main` to check if the current file is the entrypoint of the current process.

```ts index.ts icon="/icons/typescript.svg"
if (import.meta.main) {
  // this file is directly executed with `bun run`
} else {
  // this file is being imported by another file
}
```
