The tutorial provides a step-by-step guide on implementing a middleware pipeline in a Vue.js application to protect certain routes, such as those requiring user authentication or subscription. It begins by setting up a new Vue project using Vue CLI and installing necessary dependencies like Vue Router and Vuex for state management. The tutorial outlines creating components for login, dashboard, and movies, each associated with different access requirements. Using Vuex, a store is set up to track user authentication and subscription status. The guide explains how to define routes and associate them with middleware, such as guest, auth, and isSubscribed, to ensure proper route protection. A middleware pipeline function is introduced to handle multiple middlewares in sequence, leveraging Vue Router's navigation guards to manage route access. The tutorial concludes with practical examples of middleware functionality, ensuring that only authenticated and subscribed users can access specific routes, and encourages using LogRocket for monitoring and debugging Vue applications.
