Experience

Custom Authentication Module in Express Middleware

I designed and implemented a custom module, auth.js, specifically for Express middleware. This module is meticulously integrated into the Express middleware pipeline, serving a crucial role in the authentication of service requests. Its primary function is verifying user credentials, ensuring the integrity and security of all service requests. Consequently, this module is seamlessly plugged into the Express middleware, providing comprehensive authentication for all incoming service requests.
