Add Helmet Middleware to Improve HTTP Security Headers

[jikrana1]

Summary

The Express application currently does not use the helmet middleware to set secure HTTP response headers. Adding Helmet will improve the application's security by enabling common security headers with minimal configuration.

Proposed Changes

• Install and configure the helmet package.
• Register the Helmet middleware during application initialization before defining routes.
• Configure Helmet with settings that are compatible with the current application (including CORS and Socket.IO).
• Ensure existing API endpoints, WebSocket connections, and Cloudinary integrations continue to function correctly.
• Add comments where necessary to document any custom Helmet configuration.

Benefits

• Improves application security by setting common HTTP security headers.
• Helps protect against vulnerabilities such as clickjacking, MIME-type sniffing, and cross-site scripting (XSS).
• Follows Express security best practices.
• Keeps the server configuration more production-ready.
• Introduces no breaking changes to existing API functionality.

Acceptance Criteria

• Helmet is installed and configured.
• The middleware is registered before application routes.
• Existing REST API endpoints continue to work as expected.
• Socket.IO connections remain functional.
• No existing functionality is broken after enabling Helmet.

Hi ,

I would like to work on this security enhancement.

I plan to integrate the Helmet middleware into the Express application to improve HTTP security headers while ensuring compatibility with the existing API, Socket.IO, and middleware configuration.

Could you please assign this issue to me?

Thank you!

Hello @imanchalsingh I'd like to work on this issue.

Planned approach:

• Integrate the helmet middleware into the Express backend.
• Configure it using the project's existing middleware setup while ensuring compatibility with the current application.
• Verify that the application continues to function correctly and that the appropriate security headers are applied.

If this issue is still available, could you please assign it to me? Thanks!
