Web Development with Nuxt.js (Intermediate)

In this blog post, we will learn about Nuxt.js, a powerful framework for creating server-rendered Vue.js applications. We'll start by reviewing the core concepts of Vue.js, then delve into the features that make Nuxt.js a leading tool for modern web development.

Nuxt.js: An Overview

Nuxt.js is a framework for building server-rendered Vue.js applications. It provides a higher-level application framework on top of Vue.js, adding features like automatic code splitting, routing, and server-side rendering.

Core Concepts of Vue.js

Before we dive into Nuxt.js, let's review some core concepts of Vue.js:

• Vue Instance: Every Vue application starts by creating a new Vue instance. It is the root of every Vue application.
• Components: Vue.js uses a component system, which is an abstraction allowing us to build large-scale applications composed of small, self-contained, and reusable components.
• Directives: Vue.js uses HTML-based template syntax that allows you to declaratively bind the rendered DOM to the underlying Vue instance’s data. Directives are special attributes with the v- prefix.
• Routing: Vue Router is the official router for Vue.js. It deeply integrates with Vue.js core to make building Single Page Applications a breeze.

Features of Nuxt.js

Nuxt.js comes with a lot of features to help you in your development between the client side and the server side such as asynchronous data, middleware, layouts, etc.

Creating a Nuxt.js Application

Let's see how we can set up a Nuxt.js application. We will use create-nuxt-app, a tool made by the Nuxt.js team.

    // First, install the tool with npm
    npm install -g create-nuxt-app

    // Next, create a new Nuxt.js application
    create-nuxt-app my-nuxt-app
    

Follow the prompts to set up your application. Once the setup is complete, navigate into your application directory and start the development server:

    // Navigate into the application directory
    cd my-nuxt-app

    // Start the development server
    npm run dev
    

Server-Side Rendering and SEO in Nuxt.js

Nuxt.js automatically optimizes your application for performance by splitting your code into "server" and "client" bundles. During development, you will only see the "client" bundle, which is a single JavaScript file containing your entire application. However, when you build your application for production, Nuxt.js will create a separate "server" bundle. This separation allows Nuxt.js to pre-render your application on the server and send a fully-rendered page to the client. This is great for SEO and for performance in general.

Dynamic Routing in Nuxt.js

Nuxt.js automatically generates the vue-router configuration based on your file tree of Vue files inside the pages directory. To navigate between pages, we recommend to use the <NuxtLink> component.

    <template>
      <NuxtLink to="/about">About</NuxtLink>
    </template>
    

Managing State with Vuex in Nuxt.js

Nuxt.js includes Vuex by default. It automatically integrates Vuex modules into the application based on the file structure of your store directory. Here's an example of creating a Vuex store for user data:

    export const state = () => ({
      user: null
    })

    export const mutations = {
      SET_USER(state, user) {
        state.user = user
      }
    }
