# Auto-imports
[source code](https://github.com/nuxt/nuxt/blob/main/packages/kit/src/imports.ts)
Nuxt auto-imports helper functions, composables and Vue APIs to use across your application without explicitly importing them. Based on the directory structure, every Nuxt application can also use auto-imports for its own composables and plugins. With Nuxt Kit you can also add your own auto-imports. `addImports` and `addImportsDir` allow you to add imports to the Nuxt application. `addImportsSources` allows you to add listed imports from 3rd party packages to the Nuxt application.
::alert{type=info}
These functions are designed for registering your own utils, composables and Vue APIs. For pages, components and plugins, please refer to the specific sections: [Pages](/docs/api/kit/pages), [Components](/docs/api/kit/components), [Plugins](/docs/api/kit/plugins).
