Blog App with Comments

A blog app teaches relationships and nested UI.

Features

• create post,
• edit own post,
• list posts,
• view post details,
• add comment,
• delete own comment,
• author profile,
• basic moderation if admin exists.

Backend routes

GET /api/posts
POST /api/posts
GET /api/posts/:id
PATCH /api/posts/:id
DELETE /api/posts/:id
GET /api/posts/:id/comments
POST /api/posts/:id/comments
DELETE /api/comments/:id

Schema approach

Posts reference author:

authorId: ObjectId

Comments reference post and author:

postId: ObjectId
authorId: ObjectId

Comments are separate because they can grow and need pagination.

UI states

Handle:

• loading post,
• no comments,
• validation error,
• unauthorized edit/delete,
• optimistic or normal comment update.

What this project proves

• relationships,
• ownership,
• pagination,
• nested resource routes,
• role/permission thinking.
