Import meta
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.

Runtime (App) Properties
These values are statically injected and can be used for tree-shaking your runtime code.
| Property | Type | Description |
|---|---|---|
import.meta.client | boolean | True when evaluated on the client side. |
import.meta.browser | boolean | True when evaluated on the client side. |
import.meta.server | boolean | True when evaluated on the server side. |
import.meta.nitro | boolean | True when evaluated on the server side. |
import.meta.dev | boolean | True when running the Nuxt dev server. |
import.meta.test | boolean | True when running in a test context. |
import.meta.prerender | boolean | True when rendering HTML on the server in the prerender stage of your build. |
Builder Properties
These values are available both in modules and in your nuxt.config.
| Property | Type | Description |
|---|---|---|
import.meta.env | object | Equals process.env |
import.meta.url | string | Resolvable path for the current file. |
Examples
Using import.meta.url to resolve files within modules
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')
})
}
})
