Automatic Component Loading with Vite

It's very easy to auto-import components in Vue 3. If it's just one or two components, the process can be done manually.

import {createApp} from 'vue';
import GlobalComponent from './GlobalComponent.vue';
const app = createApp({})
app.component('GlobalComponent', GlobalComponent);

But, what if we want to auto-import an entire directory? For example, /components. This is where Vite and its Glob import come to our aid. Let's dive in ⚡️

Global components with Vite Glob import

First, we can use Glob import to select all files with the .vue extension.

const components = import.meta.globEager('./components/*.vue');

This results in an object with this structure:

{
    './components/AppComponent.vue'
:
    Module,
        './components/HelloWorld.vue'
:
    Module
}
}

As you can see, as a property we have the path to the component, and as a value, the module of the component itself.

Now, we can convert components into an Array with Object.entries and load them with the component method of the newly created Vue instance.

Object.entries(components).forEach(([path, component]) => {
    myApp.component(
        path
            .split('/')
            .pop()
            .replace(/\.\w+$/, ''),
        component.default
    );
});

Note that along the way, we have to perform several operations:

• Break the path into different segments, separated by / using the split method of Array.
• Keep the last segment using the pop method of Array.
• Remove the extension from the segment using the replace method of strings and a regular expression.

With all this, we already have the ability to auto-import global components in Vue 3 with Vite.

Here is the complete code:

import {createApp} from 'vue';
import './style.css';
import App from './App.vue';
const components = import.meta.globEager('./components/*.vue');
const myApp = createApp(App);
Object.entries(components).forEach(([path, component]) => {
    myApp.component(
        path
            .split('/')
            .pop()
            .replace(/\.\w+$/, ''),
        component.default
    );
});
myApp.mount('#app');
