Context

Nuxt Kit provides a set of utilities to help you work with context.

Nuxt modules allow you to enhance Nuxt's capabilities. They offer a structured way to keep your code organized and modular. If you're looking to break down your module into smaller components, Nuxt offers the useNuxt and tryUseNuxt functions. These functions enable you to conveniently access the Nuxt instance from the context without having to pass it as an argument.

When you're working with the setup function in Nuxt modules, Nuxt is already provided as the second argument. This means you can access it directly without needing to call useNuxt().

`useNuxt`

Get the Nuxt instance from the context. It will throw an error if Nuxt is not available.

Usage

import { useNuxt } from '@nuxt/kit'

const setupSomeFeature = () => {
  const nuxt = useNuxt()

  // You can now use the nuxt instance
  console.log(nuxt.options)
}

Type

function useNuxt(): Nuxt

Return Value

The useNuxt function returns the Nuxt instance, which contains all the options and methods available in Nuxt.

Property	Type	Description
`options`	`NuxtOptions`	The resolved Nuxt configuration.
`hooks`	`Hookable<NuxtHooks>`	The Nuxt hook system. Allows registering and listening to lifecycle events.
`hook`	`(name: string, (...args: any[]) => Promise<void> \| void) => () => void`	Shortcut for `nuxt.hooks.hook`. Registers a single callback for a specific lifecycle hook.
`callHook`	`(name: string, ...args: any[]) => Promise<any>`	Shortcut for `nuxt.hooks.callHook`. Triggers a lifecycle hook manually and runs all registered callbacks.
`addHooks`	`(configHooks: NestedHooks) => () => void`	Shortcut for `nuxt.hooks.addHooks`. Registers multiple hooks at once.

Examples

import { useNuxt } from '@nuxt/kit'

export const setupTranspilation = () => {
  const nuxt = useNuxt()

  if (nuxt.options.builder === '@nuxt/webpack-builder') {
    nuxt.options.build.transpile ||= []
    nuxt.options.build.transpile.push('xstate')
  }
}

import { setupTranspilation } from './setupTranspilation'

export default defineNuxtModule({
  setup () {
    setupTranspilation()
  },
})

`tryUseNuxt`

Get the Nuxt instance from the context. It will return null if Nuxt is not available.

Usage

import { tryUseNuxt } from '@nuxt/kit'

function setupSomething () {
  const nuxt = tryUseNuxt()

  if (nuxt) {
    // You can now use the nuxt instance
    console.log(nuxt.options)
  } else {
    console.log('Nuxt is not available')
  }
}

Type

function tryUseNuxt(): Nuxt | null

Return Value

The tryUseNuxt function returns the Nuxt instance if available, or null if Nuxt is not available.

The Nuxt instance as described in the useNuxt section.

Examples

import { tryUseNuxt } from '@nuxt/kit'

interface SiteConfig {
  title?: string
}

export const requireSiteConfig = (): SiteConfig => {
  const nuxt = tryUseNuxt()
  if (!nuxt) {
    return {}
  }
  return nuxt.options.siteConfig
}

import { defineNuxtModule, useNuxt } from '@nuxt/kit'
import { requireSiteConfig } from './requireSiteConfig'

export default defineNuxtModule({
  setup (_, nuxt) {
    const config = requireSiteConfig()
    nuxt.options.app.head.title = config.title
  },
})
