Backend
by ArpitRanjan0101
Overview
This repository serves as a learning playground for Node.js backend development, demonstrating fundamental concepts like HTTP server creation, Express.js routing, middleware, and MongoDB integration for CRUD operations.
Installation
node day17/index.jsEnvironment Variables
- MONGODB_URI
- AUTH_SECRET_TOKEN
Security Notes
Critical security risks identified due to hardcoded MongoDB database credentials (username and password) in multiple `database.js` files (`day14`, `day16`, `day17`). Additionally, multiple hardcoded static authentication tokens are present in `day9/middleware/auth.js` and `day9/index.js`, providing no real security. The input validation logic in `day17/index.js` for mandatory fields is also flawed and could potentially expose sensitive error messages.
