title: 'Import meta'

description: Understand where your code is running using `import.meta`.

## The `import.meta` object
|
||
|
|
||
|
With ES modules you can obtain some metadata from the code that imports or compiles your ES-module.
|
||
|
This is done through `import.meta`, which is an object that provides your code with this information.
|
||
|
Throughout the Nuxt documentation you may see snippets that use this already to figure out whether the
|
||
|
code is currently running on the client or server side.

## Examples
|

|
|

### Using `import.meta.url` to resolve files within modules
|
||
|
|
||
|
```ts [modules/my-module/index.ts]
|
||
|
import { createResolver } from 'nuxt/kit'
|
||
|
|
||
|
// Resolve relative from the current file
|
||
|
const resolver = createResolver(import.meta.url)
|
||
|
|
||
|
export default defineNuxtModule({
|
||
|
meta: { name: 'myModule' },
|
||
|
setup() {
|
||
|
addComponent({
|
||
|
name: 'MyModuleComponent',
|
||
|
// Resolves to '/modules/my-module/components/MyModuleComponent.vue'
|
||
|
filePath: resolver.resolve('./components/MyModuleComponent.vue')
|
||
|
})
|
||
|
}
|
||
|
})
|
||
|
```
