Hands-on Nuxt.js Web Development

By: Lau Tiam Kok

Overview of this book

Nuxt.js is a progressive web framework built on top of Vue.js for server-side rendering (SSR). With Nuxt.js and Vue.js, building universal and static-generated applications from scratch is now easier than ever before. This book starts with an introduction to Nuxt.js and its constituents as a universal SSR framework. You'll learn the fundamentals of Nuxt.js and find out how you can integrate it with the latest version of Vue.js. You'll then explore the Nuxt.js directory structure and set up your first Nuxt.js project using pages, views, routing, and Vue components. With the help of practical examples, you'll learn how to connect your Nuxt.js application with the backend API by exploring your Nuxt.js application’s configuration, plugins, modules, middleware, and the Vuex store. The book shows you how you can turn your Nuxt.js application into a universal or static-generated application by working with REST and GraphQL APIs over HTTP requests. Finally, you'll get to grips with security techniques using authorization, package your Nuxt.js application for testing, and deploy it to production. By the end of this web development book, you'll have developed a solid understanding of using Nuxt.js for your projects and be able to build secure, end-to-end tested, and scalable web applications with SSR, data handling, and SEO capabilities.

Writing route middlewares in Nuxt

As always, once we understand how middleware works in Vue, it will then be easier to work with it in Nuxt as Nuxt has taken care of Vue Router for us. In the coming sections, we will learn how to work with global and per-route middlewares for Nuxt apps.

In Nuxt, all middleware should be kept in the /middleware/ directory, and the middleware filename will be the name of the middleware. For example, /middleware/user.js is the user middleware. A middleware gets the Nuxt context as its first argument:

export default (context) => { ... }

Additionally, middleware can be asynchronous:

export default async (context) => {
const { data } = await axios.get('/api/path')

In universal mode, middlewares are called on the server side once (for example, when first requesting the Nuxt app or when refreshing a page) and then on the client side when navigating to other routes. On the other hand, middlewares are always called on the client side whether...
