To handle sessions and state management, Vuex store in Nuxt Js application can be leveraged. Vuex is a state management pattern and library for Vue.js applications. It serves as a centralized store for all the components in an application.

You can handle sessions in Nuxt Js using the nuxt/session module or similar libraries. When a user logs in, a session is created, and when they log out, the session is destroyed. The sessions can be stored on the server using various methods such as in-memory store, or databases like PostgreSQL, MongoDB, Redis, etc.

Building Secure Applications with Nuxt Js and Nest Js

Security should be a top priority in any application. Nest Js and Nuxt Js both come with built-in features and utilities to help secure your application. Nest Js has a robust Authentication and Authorization mechanism that, when combined with Express or Fastify middleware, can secure your backend. Furthermore, it allows for integration with Passport.js, a popular authentication middleware for Node.js.

Nuxt Js, on the other hand, provides basic protection out of the box against cross-site scripting (XSS) and other common attacks. The nuxtjs/auth module can be integrated for authentication and protecting routes, while nuxtjs/axios module allows secure HTTP communication between the client and the server. Modules like helmet can also be used to secure Express apps by setting various HTTP headers.

It’s essential not only to use these features but also to follow best practices for robust security. Always sanitize user input and be diligent with use of data from third-party APIs. Implement strict session management and ensure secure communication between client and server.

Remember, while both Nest Js and Nuxt Js provide great tools and utilities, the security of your application ultimately depends on how effectively these tools are used and the overall architecture of your application.
