Vue Tip: Speed Up Initial Load Using Async Components

The traditional, synchronous way of loading components is:

import MyComponent from './MyComponent.vue'

In large applications, it makes sense to split the code into smaller chunks and only load it from the server when needed.

Vue 3 therefore provides the defineAsyncComponentfunction:

import { defineAsyncComponent } from 'vue' const AsyncComp = defineAsyncComponent(() => { return new Promise((resolve, reject) => { // ...load component from server resolve(/* loaded component */) }) })

Now we can use AsyncComp as a standard component in Vue.

Here are the docs for Async Components in Vue 3.

The syntax for Vue 2 is not that different:

const AsyncComponent = () => import('./components/LazyLoadingFTW.vue')
