NuxtJS is a framework built on top of Vue that offers additional features and benefits, especially for large-scale and content-driven projects. It provides server-side rendering, which can improve performance and SEO.

In this course, you’ll get briefly introduced to Vue, covering components, views, routing, state management, and others. Then, you’ll get acquainted with NuxtJS and learn about configuration and structure for NuxtJS projects. Further, you’ll learn about different NuxtJS rendering modes and the key factors to consider when choosing a mode for the example survey application project. You’ll work with NuxtJS components, pages, layouts, plugins, and middleware. You’ll then develop a complete server-side rendered Vue.js application using NuxtJS and learn about optimizing server-side rendered applications for SEO and performance.

By the end of the course, you’ll possess the skills to develop, deploy, and optimize a feature-rich, server-side rendered web application utilizing Vue and NuxtJS.

Build a Modern Server-Side Rendered Vue Application with NuxtJS

In front-end web development, **route guards** are objects used to control access to certain routes in an application. They can be used to implement authentication, authorization, and other security measures. Additionally, they can control the availability of routes in different environments or perform other tasks that need to be done before a route is displayed. In Nuxt, the feature of a route guard is supported by a function called a middleware.

For the survey application, a route guard is needed to prevent unauthorized access to the `admin` routes where surveys can be created and responses can be viewed.

# Nuxt middleware

In Nuxt, the concept of middleware is applied in two instances: on the application layer and the server-side API.

On the **application layer**, Nuxt middleware is a function that runs before navigating to a route and rendering the page. Its primary purpose is to perform certain queries or logic to determine whether the requested page should be rendered. 

The middleware function accepts two parameters: `to` and `from`. The `to` parameter is an object that contains all the information about the destination route, while the `from` parameter contains information about the starting route.

However, it's important not to confuse Nuxt middleware with server-side middleware, which is used on the server-side of applications. Server middleware runs before the event handler and is often employed for tasks, like request preprocessing, logging, or adding additional data to the request object.

The key differences between Nuxt middleware and server-side middleware are as follows:

- Nuxt middleware files are placed in the `/middleware` directory, while server middleware is placed in the `/server/middleware` directory.

- Nuxt middleware runs before the page is rendered, while server middleware is a function that is running before the event handler. Server middleware is not expected to return any values, but it can extend the request object or perform logging.

## Types of Nuxt middleware
- **Inline route middleware:** This type of middleware is defined directly on the page. It’s most likely tailored for the use of the current page and cannot be reused on another page.
