Nuxt.js Interview Questions (10+ Years Experience)

  1. What is Nuxt.js and what are its core advantages over using Vue.js directly?

    • Answer: Nuxt.js is a higher-level framework built on top of Vue.js that offers a structured approach to building server-side rendered (SSR) or statically generated (SSG) Vue.js applications. Its core advantages include improved SEO, faster initial load times (due to SSR/SSG), automatic code splitting, and a convention-over-configuration approach that simplifies project setup and maintenance. It provides features like routing, data fetching, and middleware out of the box, reducing boilerplate code significantly.

  2. Explain the difference between Nuxt.js's SSR, SSG, and SPA modes. When would you choose each?

    • Answer: SSR (Server-Side Rendering) renders the application on the server and sends the fully rendered HTML to the client. This is great for SEO and initial load time but can be slower for subsequent interactions. SSG (Static Site Generation) generates the entire application at build time, resulting in the fastest possible load times and excellent SEO. It's ideal for content-heavy websites with minimal dynamic content. SPA (Single Page Application) mode renders the application entirely on the client-side, similar to a traditional Vue.js application. It offers good performance for interactive applications but can be less SEO-friendly and have a slower initial load time.

  3. How does Nuxt.js handle routing? Describe the structure of a Nuxt.js route and its components.

    • Answer: Nuxt.js uses a file-system based routing system. Pages are defined by placing `.vue` files inside the `pages` directory. The file path determines the route. For example, `pages/about.vue` creates the `/about` route. A route component typically consists of `
