Enhancement Request: Add express-validator

📌 Description

Currently, input fields (username, bio, social links) do not have strict validation. This can allow invalid or insecure data into the database. We will use express-validator to enforce input rules.

🛠 Middleware

• express-validator

🚀 Implementation

1. Install: npm install express-validator
2. Add validation rules in controllers:

   
   import { body, validationResult } from "express-validator";
   body("username").isLength({ min: 3 })
   
   body("bio").isLength({ max: 150 })
   
   body("social_links.website").optional().isURL()
   
   

3. Return errors if validation fails using validationResult.

✅ Expected Outcome

• Ensure valid usernames, bios, and links.
• Block invalid or unsafe data from being saved.
