Third-party scripts can be a real pain point for developers. We've all been there - endlessly debugging, dealing with compatibility issues and wrestling with performance problems. But what if there was a better way? Enter Nuxt Scripts, the game-changing module that's about to revolutionize the way you handle third-party scripts in your Nuxt applications.
When integrating third-party scripts, you might think, “How bad could it be?” But every added script can have unintended consequences:
In fact, the HTTP Archive’s 2024 report on third-party scripts shows that:
Did you know? These complex chains often contribute significantly to slow load times, with third-party resources accounting for a substantial part of total page load times, impacting user experience and SEO.
Nuxt Scripts addresses these challenges head-on by offering a declarative and composable API to manage third-party scripts. Created by Harlan Wilton, a core team member of Nuxt, VueUse, and UnJS — and the author of popular tools like Unlighthouse, Unhead, and Nuxt SEO.
Nuxt Scripts simplifies the often tedious process of script management.Unlike traditional methods that require extensive manual configuration, this module provides a clean API, enabling you to seamlessly add and configure external scripts within your Nuxt app. With Nuxt Scripts, you don’t have to worry about execution order or complex interactions, making third-party script management effortless and efficient.
Nuxt Scripts isn't just another way to load third-party scripts — it’s a comprehensive, performance-focused solution designed for seamless integrations and developer-friendly experiences. From optimizing load times to ensuring privacy compliance, here's how it stands out:
crossorigin="anonymous"
, and referrerpolicy="no-referrer"
help minimize user data exposure.To harness the power of Nuxt Scripts, follow these simple steps:
Install Nuxt Scripts:
npx nuxi@latest module add scripts
Register the module in your nuxt.config.ts
file if not registered already:
export default defineNuxtConfig({
modules: ['@nuxtjs/scripts']
})
Let's create a simple example using the useScript()
composable from Nuxt Scripts with Vue.js Script Setup syntax with the Composition API. We'll integrate the popular Confetti library to dynamically celebrate user interactions:
<!-- app.vue -->
<template>
<div>
<h1>Mastering Nuxt</h1>
<button @click="triggerConfetti">Celebrate!</button>
</div>
</template>
<script setup>
const triggerConfetti = async () => {
await useScript("https://cdn.jsdelivr.net/npm/js-confetti@latest/dist/js-confetti.browser.js");
const jsConfetti = new JSConfetti();
jsConfetti.addConfetti();
};
</script>
In this example, we define an asynchronous function triggerConfetti
that uses the useScript
composable provided by Nuxt Scripts to dynamically load the js-confetti
library from JS Delivr CDN. The useScript
composable ensures that the script is loaded only when it's needed, preventing unnecessary blocking of the page’s critical resources.
Once the script is successfully loaded, the function creates a new instance of JSConfetti
and calls the addConfetti()
method to trigger the confetti effect.
This approach demonstrates how Nuxt Scripts can be used to manage external scripts dynamically while keeping the application’s performance intact by loading scripts only when required.
Here’s the result:
Using Confetti JS with Nuxt Scripts
Nuxt Scripts introduces a warmup strategy to optimize the loading of your scripts. While your Nuxt app is hydrating, the network might be idle. Nuxt Scripts leverages this idle time to preemptively insert link tags, like <link rel="preload">
or <link rel="preconnect">
, into the document head, ensuring scripts are ready to load when needed.
For example, the warmup
function explicitly warms up a script by adding these tags. This is particularly useful for scripts triggered dynamically. In the code below, we use a manual trigger for the js-confetti
library, preloading it on hover for faster execution:x
<!-- app.vue -->
<template>
<div>
<h1>Mastering Nuxt</h1>
<button
@mouseenter="confettiScript.warmup('preload')"
@click="triggerConfetti"
>
Celebrate!
</button>
</div>
</template>
<script setup>
const confettiScript = useScript("https://cdn.jsdelivr.net/npm/js-confetti@latest/dist/js-confetti.browser.js", {
trigger: "manual",
});
const triggerConfetti = async () => {
await confettiScript.load();
const jsConfetti = new JSConfetti();
jsConfetti.addConfetti();
};
</script>
Here’s what happens:
warmup('preload')
method preloads the script by inserting a <link rel="preload">
tag. This ensures faster script loading when the button is clicked.load()
method, and the confetti effect is triggered.By combining manual triggers and the warmup strategy, you can fine-tune script performance for both responsiveness and efficiency. This technique is ideal for interactive features where snappy responses are key!
