In modern web applications, the user experience is critical. If we can preload some of the page components that users may navigate to in the future, we can significantly improve overall performance. This is where thepreloadRouteComponents The purpose of the function.

What is it?preloadRouteComponents？

preloadRouteComponents is a method that allows us to manually preload individual page components in our application. By preloading a route's components before a user may access that route, we can ensure that those components are ready when the user navigates to that route, thus avoiding loading delays and improving the user experience.

Why usepreloadRouteComponents?

  • improve performance: With preloading, the user accesses a new page faster because the components have been loaded into memory ahead of time.
  • Smooth user experience: Avoid the "white screen" phenomenon of page loading when the user is navigating.

How to usepreloadRouteComponents

1. Basic usage

Generally, we have some sort of triggering event in our application, such as a user clicking a button, or we're about to invoke thenavigateTo function to make a page jump. Until then, we can call thepreloadRouteComponents method for preloading.

2. Example code

Let's walk through a simple example of how to use thepreloadRouteComponents。

<template>
  <div>
    <button @click="handleLogin">Log in and access the dashboard</button>
  </div>
</template>

<script setup>
const handleLogin = async () => {
  // preloaded '/dashboard' routed component
  preloadRouteComponents('/dashboard')

  // Simulate an asynchronous login process
  const results = await $fetch('/api/authentication')

  if () {
    // Navigate to Dashboard after successful login
    await navigateTo('/dashboard')
  }
}
</script>

Code Details

  • import method: We start with thenuxt/app is imported in thepreloadRouteComponents cap (a poem)navigateTo function.

  • button click event: When the user clicks on the "Login and Access Dashboard" button, we execute thehandleLogin function.

  • preloaded component: CallpreloadRouteComponents('/dashboard') method, which will preload the/dashboard Components needed for routing.

  • Analog Login: we pass$fetch Calls the back-end authentication API to simulate a login process.

  • navigator: If a valid login token is obtained, we use thenavigateTo('/dashboard') Jump to the Dashboard.

caveat

  • preloadRouteComponents It only works on the client side, it has no effect on the server side.
  • If you are already using theNuxtLink component, Nuxt will automatically help you preload the relevant routes, so you don't need to call them manually.
