The admin backend for my blog API! I Implemented secure JWT sessions, soft deletes with audit trails for content moderation, and a dashboard with key platform metrics. It's all about giving admin the tools they need to manage the community effectively.#NodeJS #Backend #AP

In today’s class with @Itz_Steavean, I learned how to use middleware to validate JWTs in Node.js
- Verifies token from headers
- Blocks unauthorized requests
- Keeps protected routes safe
One step closer to building secure APIs

I just learnt with @Itz_Steavean how to implement secure login authentication using JWTs!

- Validates input
- Checks user creds
- ⁠Use bcrypt for password match
- ⁠Generates JWT for auth

Next step: Add centralized response handling and a middleware to validate requests
