Resolving
Nuxt Kit provides a set of utilities to help you resolve paths. These functions allow you to resolve paths relative to the current module, with unknown name or extension.
Sometimes you need to resolve a paths: relative to the current module, with unknown name or extension. For example, you may want to add a plugin that is located in the same directory as the module. To handle this cases, nuxt provides a set of utilities to resolve paths. resolvePath and resolveAlias are used to resolve paths relative to the current module. findPath is used to find first existing file in given paths. createResolver is used to create resolver relative to base path.
resolvePath
Resolves full path to a file or directory respecting Nuxt alias and extensions options. If path could not be resolved, normalized input path will be returned.
Type
async function resolvePath (path: string, options?: ResolvePathOptions): Promise<string>
Parameters
path
Type: string
Required: true
Path to resolve.
options
Type: ResolvePathOptions
Default: {}
Options to pass to the resolver. This object can have the following properties:
cwd(optional)
Type:string
Default:process.cwd()
Current working directory.alias(optional)
Type:Record<string, string>
Default:{}
Alias map.extensions(optional)
Type:string[]
Default:['.js', '.mjs', '.ts', '.jsx', '.tsx', '.json']
Extensions to try.
Examples
// https://github.com/P4sca1/nuxt-headlessui
import { defineNuxtModule, resolvePath } from '@nuxt/kit'
import { join } from 'pathe'
const headlessComponents: ComponentGroup[] = [
{
relativePath: 'combobox/combobox.js',
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 group.exports) {
addComponent(
{
name: e,
export: e,
filePath: join(root, group.relativePath),
chunkName: group.chunkName,
mode: 'all'
}
)
}
}
}
})
resolveAlias
Resolves path aliases respecting Nuxt alias options.
Type
function resolveAlias (path: string, alias?: Record<string, string>): string
Parameters
path
Type: string
Required: true
Path to resolve.
alias
Type: Record<string, string>
Default: {}
Alias map. If not provided, it will be read from nuxt.options.alias.
findPath
Try to resolve first existing file in given paths.
Type
async function findPath (paths: string | string[], options?: ResolvePathOptions, pathType: 'file' | 'dir'): Promise<string | null>
interface ResolvePathOptions {
cwd?: string
alias?: Record<string, string>
extensions?: string[]
}
Parameters
paths
Type: string | string[]
Required: true
A path or an array of paths to resolve.
options
Type: ResolvePathOptions
Default: {}
Options to pass to the resolver. This object can have the following properties:
cwd(optional)
Type:string
Default:process.cwd()
Current working directory.alias(optional)
Type:Record<string, string>
Default:{}
Alias map.extensions(optional)
Type:string[]
Default:['.js', '.mjs', '.ts', '.jsx', '.tsx', '.json']
Extensions to try.
pathType
Type: 'file' | 'dir'
Default: 'file'
Type of path to resolve. If set to 'file', the function will try to resolve a file. If set to 'dir', the function will try to resolve a directory.
createResolver
Creates resolver relative to base path.
Type
function createResolver (basePath: string | URL): Resolver
interface Resolver {
resolve (...path: string[]): string
resolvePath (path: string, options?: ResolvePathOptions): Promise<string>
}
interface ResolvePathOptions {
cwd?: string
alias?: Record<string, string>
extensions?: string[]
}
Parameters
basePath
Type: string
Required: true
Base path to resolve from.
Examples
// https://github.com/vuejs/pinia/blob/v2/packages/nuxt
import {
defineNuxtModule,
isNuxt2,
createResolver,
} from '@nuxt/kit'
export default defineNuxtModule({
setup(options, nuxt) {
const resolver = createResolver(import.meta.url)
nuxt.hook('modules:done', () => {
if (isNuxt2()) {
addPlugin(resolver.resolve('./runtime/plugin.vue2'))
} else {
addPlugin(resolver.resolve('./runtime/plugin.vue3'))
}
})
}
})
