Mastering Nuxt

Nuxt Tip 💡 The stale-while-revalidate pattern: Serve fast, update in background. Users get instant responses (even if slightly stale) and the cache rebuilds in the background. Here's how you can do this in Nuxt/ Nitro.👇

Nuxt 4's cachedEventHandler is a fantastic feature.🔥 All you do is wrap your API routes to cache responses!

Unpopular opinion: Many plugins should be composables instead. Plugins load on every page. But composables load only when you use them.

Nuxt Tip 💡 Want to reduce your initial bundle size? Use the Lazy prefix on component. Components behind v-if still get bundled unless you add "Lazy" to the name. Then they only load when needed.

💨 Nuxt 3 is fast by default. But the real gains come from how you use it. Hybrid rendering, lazy loading, smart caching, image optimization, and Core Web Vitals explained in one practical guide 👇 https://masteringnuxt.com/blog/performance-optimization-in-nuxt-3

Happy 2026! 🎆 May your Nuxt apps load faster, your components stay lazy, and your dev workflow stay blissfully bug-free. What feature or improvement do you really hope Nuxt brings in 2026? 🔥

If you encounter an error during server-side rendering, Nuxt provides the `<NuxtClientFallback>` component to display fallback content. It shows a custom UI when a server-rendered component fails. You must enable it by setting `experimental.clientFallback` to `true`.

Happy Holidays from the Mastering Nuxt team 💚 We want to send a big thank you to our amazing community of devs & Nuxt enthusiasts. Here’s to more coding, creativity, and incredible Nuxt apps in 2026 💫

When working with Nuxt, the `nitroApp` object inside plugins gives you access to various runtime hooks. These hooks include `close`, `error`, `render:response`, `request`, `beforeResponse`, & `afterResponse`. You can use these to run custom logic at different stages of the server lifecycle.

Nuxt Tip Of The Week 💡 When you want to create a redirect in a server route, Nuxt lets you use the `sendRedirect` method from h3. By default, this sends a 302 (temporary) redirect, but you can specify a different status code if needed.

Tired of passing props through a maze of components? 🌀 Learn how `useState` keeps your app reactive, SSR-ready, and perfectly simple - no complex setup, no data leaks, just clean global state that works. https://masteringnuxt.com/blog/understanding-usestate-in-nuxt-the-simple-way-to-share-state

Nuxt Tip Of The Day💡 With Nuxt, since version 3.9, you can control how fetch requests are deduplicated using the dedupe parameter in the useFetch composable. By setting dedupe to 'cancel', the previous request is cancelled and a new one is made whenever parameters change.

Nuxt Tip💡 With Nuxt, you can access the entire payload sent from the server to the client using the useNuxtApp composable. This allows you to inspect all the data and state transferred during SSR or hydration.

💡 Did you know that with Nuxt you can access the entire payload sent from the server to the client using the `useNuxtApp` composable? This allows you to inspect all the data and state transferred during SSR or hydration.

Tip of the day 💡 When working with Nuxt, you can control where your code runs by checking the environment. Use if (!import.meta.server) to skip code on the server, and if (!import.meta.client) to skip code on the client.

When writing unit tests, Nuxt provides a way to opt-in to a Nuxt environment by adding `.nuxt.` to your test filenames. For example, you can name your test file like this 👇

Tip of the day 💡 In Nuxt you can pass route objects to `navigateTo`, similar to `router.push` in Vue Router. This enables navigation using named routes, query parameters, or hash fragments.

In Nuxt, you might need to display debug info or tools like a DevAccountSwitcher component that should only be visible during development. 🤓 To do this, wrap your component with a `&lt;DevOnly&gt;` tag in your layout file. This component will be excluded from your production build.

If you want to run code on the client before Nuxt does any initialization, use the `onPreHydrate` composable. This lets you manipulate the DOM or add event listeners using only vanilla JavaScript:

You can easily include global CSS files in every page by using the css config value in Nuxt. This gives you consistent styling across your entire Nuxt app.

Did you know that when using auth in a Nuxt app, we need to make sure that the cookie is passed from the frontend to the backend? 🙌 We can do that with useRequestHeaders (or useRequestHeader):

💡When working with Nuxt, it's common to need different configurations for dif. environments, like dev, testing, or prod. Instead of using conditional logic with `process.env.NODE_ENV`, you can use special keys in your Nuxt config for a cleaner and more type-safe approach.

💡 Tip of the day: Modules can only affect your Nuxt app during build time. But we can use methods from @nuxt/kit to do things that influence the runtime behaviour:

When do we use `NuxtErrorBoundary` in Nuxt? 🤔 We should wrap it around distinct chunks of functionality where you can handle a group of potential errors together: - `NuxtPage` components that represent nested routes - Widgets on a dashboard - Modals

Did you know that when you need to set up redirects, Nuxt makes it easy using route rules in your configuration? 💻 You can define a redirect for any route, and by default, it uses a temporary 307 status code. This is the simplest & most efficient way to handle basic redirects.

Learn how the NuxtErrorBoundary component in Nuxt 3 works under the hood to gracefully handle client-side errors. This deep dive explores its powerful features, source code, and practical use cases. 💻 By Michael Thiessen. https://masteringnuxt.com/blog/how-nuxterrorboundary-works

For debugging purposes, Nuxt can add a custom class to a `NuxtLink` once its route has been prefetched. 🧠 You can specify this class using the `prefetched-class` prop, which helps you visually identify prefetched links during development.

💡Tip of the day: In Nuxt, you can validate the request body before using it by leveraging readValidatedBody from h3. Provide a validation function to ensure the body meets your requirements.

💡 Tip of the day: In Nuxt, you can check for specific error codes like 404 using the statusCode property from the useError composable. This lets you show a custom message for not found pages, while handling other errors differently.

How do you handle user roles and permissions in your Nuxt apps? Any best practices to share?

Did you know with Nuxt, you can use `mountSuspended` to mount your app at a specific route by passing the App component and a route option? 💻 This is useful for testing route-specific content or behavior in your Nuxt application.

You can configure Nuxt to treat any folder as a global components directory by updating your `nuxt.config` file. 🗃️ For example, to add a custom folder for global components:

What’s your strategy for handling authentication in Nuxt? Do you use a module or roll your own? 🤔

💡 Tip of the day: Within Nuxt, the `useLoadingIndicator` composable is used by the `&lt;NuxtLoadingIndicator&gt;` component. You can also trigger it manually in plugins using the `page:loading:start` and `page:loading:end` hooks.
