Added a new comment feature ( roll no : 10393)

[saumyajain03]

Overview

Implemented a new comment feature for the Social-Media-A backend. This allows users to add, view, and delete comments on posts.

Changes Made

• Created models/commentModel.js for storing comments linked to posts and users.
• Added controllers/commentController.js with endpoints to create, get, and delete comments.
• Set up routes/commentRoutes.js to handle POST, GET, and DELETE requests for comments.
• Registered comment routes in the main app file.
• Ensured authentication is required for adding and deleting comments.

Usage

• POST /api/comments/:postId to add a comment.
• GET /api/comments/:postId to retrieve all comments for a post.
• DELETE /api/comments/:commentId to remove a comment (requires authentication).

Reference

Feature implementation structure follows existing post routes and controllers for consistency.
