Programmatic Usage

Programmatic usage can be helpful when you want to use Nuxt programmatically, for example, when building a CLI tool or test utils.

loadNuxt

Load Nuxt programmatically. It will load the Nuxt configuration, instantiate and return the promise with Nuxt instance.

Type

async function loadNuxt (loadOptions?: LoadNuxtOptions): Promise<Nuxt>

interface LoadNuxtOptions extends LoadNuxtConfigOptions {
  dev?: boolean
  ready?: boolean
}

Parameters

loadOptions

Type: LoadNuxtOptions

Default: {}

Loading conditions for Nuxt. loadNuxt uses c12 under the hood, so it accepts the same options as c12.loadConfig with some additional options:

• dev (optional)
  Type: boolean
  Default: false
  If set to true, Nuxt will be loaded in development mode.
• ready (optional)
  Type: boolean
  Default: true
  If set to true, Nuxt will be ready to use after the loadNuxt call. If set to false, you will need to call nuxt.ready() to make sure Nuxt is ready to use.

buildNuxt

Build Nuxt programmatically. It will invoke the builder (currently @nuxt/vite-builder or @nuxt/webpack-builder) to bundle the application.

Type

async function buildNuxt (nuxt: Nuxt): Promise<any>

Parameters

nuxt

Type: Nuxt

Required: true

Nuxt instance to build. It can be retrieved from the context via useNuxt() call.

loadNuxtConfig

Load Nuxt configuration. It will return the promise with the configuration object.

Type

async function loadNuxtConfig (options: LoadNuxtConfigOptions): Promise<NuxtOptions>

Parameters

options

Type: LoadNuxtConfigOptions

Required: true

Options to pass in c12 loadConfig call.

writeTypes

Generates tsconfig.json and writes it to the project buildDir.

Type

function writeTypes (nuxt?: Nuxt): void

interface Nuxt {
  options: NuxtOptions
  hooks: Hookable<NuxtHooks>
  hook: Nuxt['hooks']['hook']
  callHook: Nuxt['hooks']['callHook']
  addHooks: Nuxt['hooks']['addHooks']
  ready: () => Promise<void>
  close: () => Promise<void>
  server?: any
  vfs: Record<string, string>
  apps: Record<string, NuxtApp>
}

Parameters

nuxt

Type: Nuxt

Required: true

Nuxt instance to build. It can be retrieved from the context via useNuxt() call.
