Is it possible to handle user roles solely using JavaScript?

Hey there! I'm new to front-end development and I have a question. Can JavaScript alone be used to manage user authorities? I'm interested in creating a Student Management System with login features where the admin can add, delete, and update student data, while other users can only log in and read information. Is this functionality possible on the client-side, or does it need to be done server-side?

Answer №1

Implementing access control solely on the client-side opens up vulnerabilities that can be exploited by attackers, even those with minimal experience:

  1. With access to the source code, a hacker can easily manipulate it to uncover hidden features or bypass any security measures put in place.
  2. If all security logic is contained within client-side JavaScript, the backend system is left vulnerable, allowing hackers to directly access APIs and perform unauthorized actions without interacting with the frontend.

This approach may be suitable for prototype projects or demonstrations, but it is not recommended for applications intended for public use.
