Overview of this book

Vue.js is a progressive web framework for building professional user interfaces for your web applications. With Vue.js 3, the frontend framework is reinforced with architectural enhancements, new base languages, new render processes, and separated core components. The book starts with recipes for implementing Vue.js 3’s new features in your web development projects and migrating your existing Vue.js apps to the latest version. You will get up and running with TypeScript with Vue.js and find succinct solutions to common challenges and pitfalls faced in implementing components, derivatives, and animation, through to building plugins, adding state management, routing, and developing complete single-page applications (SPAs). As you advance, you'll discover recipes to help you integrate Vue.js apps with Nuxt.js in order to add server-side rendering capabilities to your SPAs. You'll then learn about the Vue.js ecosystem by exploring modern frameworks such as Quasar, Nuxt.js, Vuex, and Vuetify in your web projects. Finally, the book provides you with solutions for packaging and deploying your Vue.js apps. By the end of this Vue.js book, you'll be able to identify and solve challenges faced in building Vue.js applications and be able to adopt the Vue.js framework for frontend web projects of any scale.

The authentication middleware takes place before the router changes, so we can handle everything and send the user to the correct route.

  1. In the src/router folder, create a new folder called middleware, then create and open a new file called authentication.js.
  1. In this file, we will create a default export function that will have three function parameters – to, from, and next. The to and from parameters are objects, and the next parameter is a callback function:
export default (to, from, next) => {
};
  1. We need to check whether the route that we are being redirected to has an authenticated meta property set to true and whether we have a sessionStorage item with the 'auth' key. If we pass those validations, we can execute the next callback:
