Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

unplugin-vue-components

NPM version

On-demand components auto importing for Vue.

Features
  • 💚 Supports both Vue 2 and Vue 3 out-of-the-box.
  • ✨ Supports both components and directives.
  • ⚡️ Supports Vite, Webpack, Vue CLI, Rollup, esbuild and more, powered by unplugin.
  • 🏝 Tree-shakable, only registers the components you use.
  • 🪐 Folder names as namespaces.
  • 🦾 Full TypeScript support.
  • 🌈 Built-in resolvers for popular UI libraries.
  • 😃 Works perfectly with unplugin-icons.

Installation

npm i unplugin-vue-components -D

vite-plugin-components has been renamed to unplugin-vue-components, see the migration guide.

// vite.config.ts
import Components from 'unplugin-vue-components/vite'

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

// rollup.config.js
import Components from 'unplugin-vue-components/rollup'

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

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

You might not need this plugin for Nuxt. Use @nuxt/components instead.

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

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

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

Usage

Use components in templates as you would usually do, it will import components on demand, and there is no import and component registration required anymore! If you register the parent component asynchronously (or lazy route), the auto-imported components will be code-split along with their parent.

It will automatically turn this

<template>
  <div>
    <HelloWorld msg="Hello Vue 3.0 + Vite" />
  </div>
</template>

<script>
export default {
  name: 'App'
}
</script>

into this

<template>
  <div>
    <HelloWorld msg="Hello Vue 3.0 + Vite" />
  </div>
</template>

<script>
import HelloWorld from './src/components/HelloWorld.vue'

export default {
  name: 'App',
  components: {
    HelloWorld
  }
}
</script>

TypeScript

To get TypeScript support for auto-imported components, there is a PR to Vue 3 extending the interface of global components. Currently, Volar has supported this usage already. If you are using Volar, you can change the config as following to get the support.

Components({
  dts: true, // enabled by default if `typescript` is installed
})

Once the setup is done, a components.d.ts will be generated and updates automatically with the type definitions. Feel free to commit it into git or not as you want.

Make sure you also add components.d.ts to your tsconfig.json under include.

Importing from UI Libraries

We have several built-in resolvers for popular UI libraries like Vuetify, Ant Design Vue, and Element Plus, where you can enable them by:

Supported Resolvers:

// vite.config.js
import Components from 'unplugin-vue-components/vite'
import {
  AntDesignVueResolver,
  ElementPlusResolver,
  VantResolver,
} from 'unplugin-vue-components/resolvers'

// your plugin installation
Components({
  resolvers: [
    AntDesignVueResolver(),
    ElementPlusResolver(),
    VantResolver(),
  ],
})

You can also write your own resolver quickly:

Components({
  resolvers: [
    // example of importing Vant
    (componentName) => {
      // where `componentName` is always CapitalCase
      if (componentName.startsWith('Van'))
        return { name: componentName.slice(3), from: 'vant' }
    },
  ],
})

If you successfully configured other UI libraries, please feel free to contribute and help others using them out-of-box. Thanks!

Types for global registered components

Some libraries might register some global components for you to use anywhere (e.g. Vue Router provides <RouterLink> and <RouterView>). Since they are global available, there is no need for this plugin to import them. However, those are commonly not TypeScript friendly, and you might need to register their types manually.

Thus unplugin-vue-components provided a way to only register types for global components.

Components({
  dts: true,
  types: [{
    from: 'vue-router',
    names: ['RouterLink', 'RouterView'],
  }],
})

So the RouterLink and RouterView will be presented in components.d.ts.

By default, unplugin-vue-components detects supported libraries automatically (e.g. vue-router) when they are installed in the workspace. If you want to disable it completely, you can pass an empty array to it:

Components({
  // Disable type only registration
  types: [],
})

Migrate from vite-plugin-components

package.json

{
  "devDependencies": {
-   "vite-plugin-components": "*",
+   "unplugin-vue-components": "^0.14.0",
  }
}

vite.config.json

- import Components, { ElementPlusResolver } from 'vite-plugin-components'
+ import Components from 'unplugin-vue-components/vite'
+ import { ElementPlusResolver } from 'unplugin-vue-components/resolvers'

export default {
  plugins: [
    /* ... */
    Components({
      /* ... */

      // `customComponentsResolvers` has renamed to `resolver`
-     customComponentsResolvers: [
+     resolvers: [
        ElementPlusResolver(),
      ],

      // `globalComponentsDeclaration` has renamed to `dts`
-     globalComponentsDeclaration: true,
+     dts: true,

      // `customLoaderMatcher` is depreacted, use `include` instead
-     customLoaderMatcher: id => id.endsWith('.md'),
+     include: [/\.vue$/, /\.vue\?vue/, /\.md$/],
    }),
  ],
}

Configuration

The following show the default values of the configuration

Components({
  // relative paths to the directory to search for components.
  dirs: ['src/components'],

  // valid file extensions for components.
  extensions: ['vue'],
  // search for subdirectories
  deep: true,
  // resolvers for custom components
  resolvers: [],

  // generate `components.d.ts` global declarations,
  // also accepts a path for custom filename
  // default: `true` if package typescript is installed
  dts: false,

  // Allow subdirectories as namespace prefix for components.
  directoryAsNamespace: false,
  // Subdirectory paths for ignoring namespace prefixes
  // works when `directoryAsNamespace: true`
  globalNamespaces: [],

  // auto import for directives
  // default: `true` for Vue 3, `false` for Vue 2
  // Babel is needed to do the transformation for Vue 2, it's disabled by default for performance concerns.
  // To install Babel, run: `npm install -D @babel/parser`
  directives: true,

  // Transform path before resolving
  importPathTransform: v => v,

  // Allow for components to override other components with the same name
  allowOverrides: false,

  // filters for transforming targets
  include: [/\.vue$/, /\.vue\?vue/],
  exclude: [/[\\/]node_modules[\\/]/, /[\\/]\.git[\\/]/, /[\\/]\.nuxt[\\/]/],
})
