10 Nuxt Interview Questions and Answers in 2023
1. How would you explain the concept of server-side rendering in Nuxt?
Server-side rendering (SSR) is a technique used in Nuxt.js to render a web page on the server instead of the client. This allows for faster page loads and improved SEO, as the content is already rendered on the server before it is sent to the client.
Nuxt.js uses a Node.js server to render the page on the server. It uses the Vue.js framework to create the page, and then renders it on the server. This allows for faster page loads, as the page is already rendered before it is sent to the client.
Nuxt.js also provides a number of features to make server-side rendering easier. These include:
- Automatic code-splitting: Nuxt.js automatically splits the code into smaller chunks, which are then rendered on the server. This helps to reduce the amount of code that needs to be sent to the client.
- Pre-rendering: Nuxt.js can pre-render pages on the server, which helps to reduce the amount of time it takes for the page to load.
- Server-side caching: Nuxt.js can cache the rendered page on the server, which helps to reduce the amount of time it takes for the page to load.
Overall, server-side rendering in Nuxt.js is a great way to improve the performance of your web application. It helps to reduce the amount of code that needs to be sent to the client, and can help to improve the page load time.

5. How would you create a Nuxt plugin to add custom functionality to your application?
Creating a Nuxt plugin to add custom functionality to an application is a relatively straightforward process.
First, create a new directory in the plugins folder of your Nuxt application. This directory should contain a file named index.js, which will be the main entry point for your plugin.
In the index.js file, you will need to export a function that will be called when the plugin is registered. This function should accept the Nuxt context as an argument. The context contains the Nuxt instance, which can be used to access the Nuxt application's configuration, store, router, and other components.
Within the function, you can add custom functionality to the Nuxt application. This could include adding custom routes, registering global components, or adding custom middleware.
Once you have added the custom functionality, you will need to register the plugin in the nuxt.config.js file. This can be done by adding the plugin to the plugins array.
Finally, you will need to build and deploy the Nuxt application for the changes to take effect.
By following these steps, you can create a Nuxt plugin to add custom functionality to your application.
