Detailed Guide to the Nuxt Kit Auto Import Function

The Nuxt Kit provides a number of tools that enable developers to use automatic import functions. These features make it easier to use helper and combinatorial functions from different modules during development without having to manually import each file.

Catalog structure and automatic import

Nuxt's auto-import feature is based on a project's directory structure, and every Nuxt application can automatically import combinatorial functions and plug-ins based on its structure. With the Nuxt Kit, you can add your own tools and functions and make them globally available, dramatically improving development efficiency.

1. Add import:addImports

1.1 Functional description

addImports Functions allow you to add single or multiple imports and make them available in your Nuxt application. Using this feature, you can seamlessly introduce functions from libraries or modules into your components.

1.2 Function signatures

function addImports(imports: Import | Import[]): void

1.3 Import connector

Import The interface has the following properties:

  • from(Required): The name of the module to be imported, must be a string.
  • priority(Optional): Priority of the import, defaults to 1. If there are multiple imports with the same name, they will be prioritized according to this attribute.
  • disabled(Optional): Boolean indicating whether this import is disabled.
  • meta(Optional): Additional information, usually used to provide a link or description of the document.
    • description(Optional): Imported description information.
    • docsUrl(optional): URL to the relevant document.
  • type(Optional): Boolean type indicating whether the import is a type import.
  • typeFrom(Optional): Specifies the source used to generate the type declaration.
  • name(Required): The name of the import being detected.
  • as(Optional): The alias to import.

1.4 Example code

The following example shows how to use theaddImports Add multiple import functions:

import { defineNuxtModule, addImports } from '@nuxt/kit';

export default defineNuxtModule({
  setup(options, nuxt) {
    const names = [
      "useStoryblok",
      "useStoryblokApi",
      "useStoryblokBridge",
      "renderRichText",
      "RichTextSchema"
    ];

    ((name) => 
      addImports({ name, from: "@storyblok/vue", as: name })
    );
  }
});

1.5 Code Parsing

In this example, we define a Nuxt module and loop through multiple functions (from the@storyblok/vue module fetch) are added to Nuxt one by one. Each function has a corresponding alias and can be used directly in Vue components without having to import them manually.

2. Add an import from the catalog:addImportsDir

2.1 Functional description

addImportsDir function is used to automatically import all files in a specified directory. It traverses the directory and automatically processes all imported items to make them available in Nuxt applications.

2.2 Function signatures

function addImportsDir(dirs: string | string[], options?: { prepend?: boolean }): void

2.3 Description of parameters

  • dirs(Required): Can be a string or an array of strings specifying the path to the directory from which to import.
  • options(Optional): Options passed to the import.
    • prepend(optional): Boolean type, if set totrueThe import will be placed at the top.

2.4 Example code

The following code example shows how to use theaddImportsDir Adds all combinatorial functions in a directory:

import { defineNuxtModule, addImportsDir, createResolver } from '@nuxt/kit';

export default defineNuxtModule({
  setup(options, nuxt) {
    const resolver = createResolver();
    addImportsDir(('./runtime/composables'));
  }
});

2.5 Code Parsing

In this example, thecreateResolver Used to build a parser that dynamically resolves the position of the current module.addImportsDir command will add a new command to the specified./runtime/composables directory to automatically find and add all combinatorial functions. This makes all combinatorial functions available in Nuxt applications, eliminating the need for developers to manually import each function separately.

3. Add the import in the source:addImportsSources

3.1 Functional description

addImportsSources function enables you to add a set of imports from a specific source without having to specify each import manually.

3.2 Function signatures

function addImportsSources(importSources: ImportSource | ImportSource[]): void

3.3 ImportSource connector

ImportSource Properties of the interface include:

  • imports(Required): The name or object to be imported.
  • from(Required): The name of the module to import from.
  • priority(Optional): Import priority, default is 1.
  • disabled(Optional): Boolean value indicating whether to disable the import.
  • meta(Optional): Additional metadata.

3.4 Example code

The following code shows how to add multiple imports from a module:

import { defineNuxtModule, addImportsSources } from '@nuxt/kit';

export default defineNuxtModule({
  setup() {
    addImportsSources({
      from: 'h3',
      imports: [
        'defineEventHandler', 
        'getQuery', 
        'getRouterParams', 
        'readBody', 
        'sendRedirect'
      ] as Array<keyof typeof import('h3')>,
    });
  }
});

3.5 Code Parsing

In this example, we start with theh3 module adds five functions as auto-import. This allows you to use these methods directly in your application without having to manually import each function used.

4. Overall workflow

  1. Creating a Nuxt Module: Create a module in your Nuxt project to define and manage your imports.
  2. Calling the Auto Import Tool: UseaddImports、addImportsDir maybeaddImportsSources function to add the required imports with the necessary configuration.
  3. Using Import: In Vue components, the imported functions are called directly without the need for an explicit import statement.

5. Frequently asked questions

5.1 How do I add multiple imports?

You can do this byaddImports function's array argument to add multiple imports at once.

5.2 How does import prioritization work?

in usingpriority attribute, if there are multiple imports with the same name, the one with the highest priority will be selected for use.

5.3 Can I import type definitions?

By setting thetype attributetrue, you can mark the import as a type import.

summarize

With Nuxt Kit's automated imports, you can more efficiently manage and work with public functions, combinatorial functions, and the Vue API, whether you're importing individually, from a catalog, or from a third-party module - all with a simple API call.
