Express.js in Action: User Role Management
In this post, I will share a code snippet that shows how to update the role of a user in a Node.js application using Express and MongoDB. The code defines a router that handles a PUT request to the endpoint?/user/:userId/role.
The request body contains the user ID and the new role to assign to the user. The request also requires authentication and authorization using two custom middlewares:?authMiddleware?and?authenticateSuperAdmin. These middlewares ensure that only a super admin can update the role of another user. The code then uses the?UserRegistrationModel?to find the user by ID and update their role in the database. Finally, the code sends a JSON response with the updated user or an error message if something goes wrong.
This code snippet demonstrates how to implement a simple but secure role-based access control system in a Node.js application. I hope you find it useful and feel free to leave your feedback or questions in the comments section below. Thank you for reading!

1 年Very useful! One thing perhaps you have been missing, probably didn't focus on that part is- validation of the body. Though normally this validation comes with client side but what if anyone tries without client side and sending the body blank, at that point mostly your role will be changed (if you don't validate this also on schema) Thank you very much.??
