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
// nuxt.config.js
export default {
buildModules: [
['unplugin-auto-import/nuxt', { /* options */ }],
],
}
This module works for both Nuxt 2 and Nuxt Vite
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 */
}),
],
})

Refer to the type definitions for more options.
See src/presets.
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
In order to properly hint types for auto-imported APIs, make sure:
- to configure
options.dts
so thatauto-imports.d.ts
file is automatically generated - to include
auto-imports.d.ts
intsconfig.json
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).
- Flexible and customizable
- Tree-shakable (on-demand transforming)
- No global population
- Relying on build tools integrations (while
vue-global-api
is pure runtime) - but hey, we have supported quite a few of them already!
