Auto-imports

Nuxt Kit provides a set of utilities to help you work with auto-imports. These functions allow you to register your own utils, composables and Vue APIs.

Auto-imports

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.

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, Components, Plugins.
