unplugin-auto-import

NPM version

Auto import APIs on-demand for Vite, Webpack, Rollup and esbuild. With TypeScript support. Powered by unplugin.


without

import { computed, ref } from 'vue'
const count = ref(0)
const doubled = computed(() => count.value * 2)

with

const count = ref(0)
const doubled = computed(() => count.value * 2)

without

import { useState } from 'react'
export function Counter() {
  const [count, setCount] = useState(0)
  return <div>{ count }</div>
}

with

export function Counter() {
  const [count, setCount] = useState(0)
  return <div>{ count }</div>
}

Install

npm i -D unplugin-auto-import
Vite
// vite.config.ts
import AutoImport from 'unplugin-auto-import/vite'

export default defineConfig({
  plugins: [
    AutoImport({ /* options */ }),
  ],
})

Example: playground/


Rollup
// rollup.config.js
import AutoImport from 'unplugin-auto-import/rollup'

export default {
  plugins: [
    AutoImport({ /* options */ }),
    // other plugins
  ],
}


Webpack
// webpack.config.js
module.exports = {
  /* ... */
  plugins: [
    require('unplugin-auto-import/webpack')({ /* options */ }),
  ],
}


Nuxt

You don't need this plugin for Nuxt, it's already builtin.


Vue CLI
// vue.config.js
module.exports = {
  configureWebpack: {
    plugins: [
      require('unplugin-auto-import/webpack')({ /* options */ }),
    ],
  },
}


Quasar
// quasar.conf.js
const AutoImportPlugin = require('unplugin-auto-import/webpack')

module.exports = {
  build: {
    chainWebpack(chain) {
      chain.plugin('unplugin-auto-import').use(
        AutoImportPlugin({ /* options */ }),
      )
    },
  },
}


esbuild
// esbuild.config.js
import { build } from 'esbuild'

build({
  /* ... */
  plugins: [
    require('unplugin-auto-import/esbuild')({
      /* options */
    }),
  ],
})


Configuration

AutoImport({
  // targets to transform
  include: [
    /\.[tj]sx?$/, // .ts, .tsx, .js, .jsx
    /\.vue$/, /\.vue\?vue/, // .vue
    /\.md$/, // .md
  ],

  // global imports to register
  imports: [
    // presets
    'vue',
    'vue-router',
    // custom
    {
      '@vueuse/core': [
        // named imports
        'useMouse', // import { useMouse } from '@vueuse/core',
        // alias
        ['useFetch', 'useMyFetch'], // import { useFetch as useMyFetch } from '@vueuse/core',
      ],
      'axios': [
        // default imports
        ['default', 'axios'], // import { default as axios } from 'axios',
      ],
      '[package-name]': [
        '[import-names]',
        // alias
        ['[from]', '[alias]'],
      ],
    },
  ],

  // Auto import for all module exports under directories
  dirs: [
    // './hooks',
    // './composables'
    // ...
  ],

  // Filepath to generate corresponding .d.ts file.
  // Defaults to './auto-imports.d.ts' when `typescript` is installed locally.
  // Set `false` to disable.
  dts: './auto-imports.d.ts',

  // Auto import inside Vue template
  // see https://github.com/unjs/unimport/pull/15
  vueTemplate: false,

  // Custom resolvers, compatible with `unplugin-vue-components`
  // see https://github.com/antfu/unplugin-auto-import/pull/23/
  resolvers: [
    /* ... */
  ],

  // Generate corresponding .eslintrc-auto-import.json file.
  // eslint globals Docs - https://eslint.org/docs/user-guide/configuring/language-options#specifying-globals
  eslintrc: {
    enabled: false, // Default `false`
    filepath: './.eslintrc-auto-import.json', // Default `./.eslintrc-auto-import.json`
    globalsPropValue: true, // Default `true`, (true | false | 'readonly' | 'readable' | 'writable' | 'writeable')
  },
})

Refer to the type definitions for more options.

Presets

See src/presets.

ESLint - eslint(no-undef)

Configure options.eslintrc, and modify your eslint configuration file.

Example:

// .eslintrc.js

module.exports = {
  /* ... */
  extends: [
    // ...
    './.eslintrc-auto-import.json',
  ],
}

ESLint Docs: Extending Configuration Files

Note: .eslintrc-auto-import.json is generated automatically, If the configuration file changes do not take effect in time, please check the configuration file, restart eslint server or the editor

TypeScript

In order to properly hint types for auto-imported APIs, make sure:

  • to configure options.dts so that auto-imports.d.ts file is automatically generated
  • to include auto-imports.d.ts in tsconfig.json

FAQ

Compare to unimport

From v0.8.0, unplugin-auto-import uses unimport underneath. unimport is designed to be a lower level tool (it also powered Nuxt's auto import). You can think unplugin-auto-import is a wrapper of it that provides more user-friendly config APIs and capability like resolvers. Development of new features will mostly happend in unimport from now.

Compare to vue-global-api

You can think of this plugin as a successor to vue-global-api, but offering much more flexibility and bindings with libraries other than Vue (e.g. React).

Pros
  • Flexible and customizable
  • Tree-shakable (on-demand transforming)
  • No global population
Cons
  • Relying on build tools integrations (while vue-global-api is pure runtime) - but hey, we have supported quite a few of them already!
