When you're working on the back-end of a full-stack app using Node.js and Express, it's really important to keep it safe. The first thing you should do is set up authentication. Here’s how I usually go about it:
Use JWT (JSON Web Tokens): This is a way to securely share information between users and your app. When users log in, you check their information, and then give them a special token.
Password Hashing: Always change passwords into a secret code before saving them in your database. Tools like bcrypt make this easy.
Authentication Middleware: Build a special helper (called middleware) to check for a valid JWT on important routes. This helps stop anyone who shouldn’t be there from getting in.
Secure Your API: Use HTTPS to protect data while it's moving around, and set up rules for CORS to manage how resources are shared.
By adding these steps, you can make your back-end a lot safer!
