The Nuxt Kit provides a number of tools to help developers resolve paths, including relative paths, module aliases, and file extension handling. This is critical for module development and plugin integration.

catalogs

1. resolvePath
2. resolveAlias
3. findPath
4. createResolver

1. resolvePath

functionality

This function resolves the full path to a file or directory based on Nuxt's alias and extension options. If the path cannot be resolved, the normalized input path is returned.

typology

async function resolvePath(path: string, options?: ResolvePathOptions): Promise<string>

parameters

• path:

  • Type:string
  • Required field:true
  • Description: The path to be parsed.

• options:

  • Type:ResolvePathOptions
  • Default Value:{}
  • Description: Options to pass to the parser.
  • Optional Attributes:
    • cwd:
      • Type:string
      • Default Value:()
      • Description: The current working directory.
    • alias:
      • Type:Record<string, string>
      • Default Value:{}
      • Description: alias mapping.
    • extensions:
      • Type:string[]
      • Default Value:['.js', '.mjs', '.ts', '.jsx', '.tsx', '.json']
      • Description: The extension to try.

typical example

import { defineNuxtModule, resolvePath } from '@nuxt/kit';
import { join } from 'pathe';

const headlessComponents = [
  {
    relativePath: 'combobox/',
    chunkName: 'headlessui/combobox',
    exports: ['Combobox', 'ComboboxLabel', 'ComboboxButton', 'ComboboxInput', 'ComboboxOptions', 'ComboboxOption'],
  },
];

export default defineNuxtModule({
  meta: {
    name: 'nuxt-headlessui',
    configKey: 'headlessui',
  },
  defaults: {
    prefix: 'Headless',
  },
  async setup(options) {
    const entrypoint = await resolvePath('@headlessui/vue');
    const root = join(entrypoint, '../components');

    for (const group of headlessComponents) {
      for (const e of ) {
        addComponent({
          name: e,
          export: e,
          filePath: join(root, ),
          chunkName: ,
          mode: 'all',
        });
      }
    }
  },
});

2. resolveAlias

functionality

This function resolves path aliases according to Nuxt's alias options.

typology

function resolveAlias(path: string, alias?: Record<string, string>): string

parameters

• path:

  • Type:string
  • Required field:true
  • Description: The path to be parsed.

• alias:

  • Type:Record<string, string>
  • Default Value:{}

typical example

import { resolveAlias } from '@nuxt/kit';

const resolvedPath = resolveAlias('~assets/images/'); // Parses as an absolute path

3. findPath

functionality

This function tries to parse the first file that exists in the given path.

typology

async function findPath(paths: string | string[], options?: ResolvePathOptions, pathType: 'file' | 'dir'): Promise<string | null>

parameters

• paths:

  • Type:string | string[]
  • Required field:true
  • Description: The path or array of paths to be parsed.

• options:

  • Type:ResolvePathOptions
  • Default Value:{}
  • Description: Options to pass to the parser.

• pathType:

  • Type:'file' | 'dir'
  • Default Value:'file'
  • Description: The type of path to be parsed. If set to'file', the function will try to parse the file; if set to'dir', the function will try to parse the directory.

typical example

import { findPath } from '@nuxt/kit';

const existingFile = await findPath(['src/', 'src/'], {}, 'file');
if (existingFile) {
  (`Found file at: ${existingFile}`);
} else {
  ('No file found.');
}

4. createResolver

functionality

This function creates a resolver relative to the base path.

typology

function createResolver(basePath: string | URL): Resolver

parameters

• basePath:
  • Type:string
  • Required field:true
  • Description: The base path to be resolved.

return value

• Returns a parser object with the following methods:
  • resolve(...path: string[]): string
  • resolvePath(path: string, options?: ResolvePathOptions): Promise<string>

typical example

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

export default defineNuxtModule({
  setup(options, nuxt) {
    const resolver = createResolver();

    ('modules:done', () => {
      addPlugin(('./runtime/plugin.vue3'));
    });
  }
});
