Blog API Project Overview

I developed a Blog API using Spring Boot, Spring JPA, Lombok, and Spring Security to provide a robust platform for managing blog content. The application includes user authentication and authorization using JWT (JSON Web Tokens) and implements CRUD operations on both blogs and comments, along with additional functionalities like publishing, archiving, liking, and disliking posts and comments. All features are integrated with pagination to manage data efficiently, and the database used is PostgreSQL.

Brief Overview:

• User Authentication: Implemented secure authentication using JSON Web Tokens (JWT).
• Blog Management: Users can create, read, update, and delete blog posts. Blogs can be published, archived, or retrieved based on status.
• Comment System: Users can add, edit, delete, and view comments on blog posts.
• Interactions: Users can like or dislike blogs and comments.
• Pagination: Implemented pagination for efficiently handling large sets of blogs and comments.
• Database: PostgreSQL is used as the database for storing all the data.

Key Features

1. User Authentication and Authorization:

• Users can register and authenticate using JWT, which secures the API endpoints.
• Example API Paths:
  • Register User: POST http://localhost:8080/api/v1/auth/register
  • Authenticate User: POST http://localhost:8080/api/v1/auth/authenticate

2. Blog Management:

• Create, Read, Update, and Delete (CRUD) operations are provided for blogs.
• Additional functionalities include:
  • Publish or Archive Blogs: Blogs can be published or archived based on user actions.
  • Pagination: All blog lists are paginated for better performance and user experience.
• Example API Paths:
  • Create Blog: POST http://localhost:8080/api/v1/blogs
  • Get All Blogs: GET http://localhost:8080/api/v1/blogs
  • Get Specific Blog by ID: GET http://localhost:8080/api/v1/blogs/{blog-id}
  • Get Blogs by Owner: GET http://localhost:8080/api/v1/blogs/owner
  • Get Archived Blogs: GET http://localhost:8080/api/v1/blogs/archived
  • Update Blog: PUT http://localhost:8080/api/v1/blogs/{blog-id}
  • Delete Blog: DELETE http://localhost:8080/api/v1/blogs/{blog-id}

3. Comment Management:

• Users can add, view, and delete comments on blog posts.
• Additional functionalities include:
  • Liking/Disliking Comments: Users can express their opinions on comments.
  • Pagination: Comment lists are paginated for easier navigation and management.
• Example API Paths:
  • Create Comment: POST http://localhost:8080/api/v1/blogs/{blog-id}/comments
  • Get All Comments: GET http://localhost:8080/api/v1/blogs/{blog-id}/comments

4. Like/Dislike Feature:

• Users can like or dislike blogs and comments, providing interactive feedback mechanisms.
• Example API Paths:
  • Like Blog: POST http://localhost:8080/api/v1/blogs/{blog-id}/like
  • Dislike Blog: DELETE http://localhost:8080/api/v1/blogs/{blog-id}/dislike
  • Like Comment: POST http://localhost:8080/api/v1/blogs/{blog-id}/comments/{comment-id}/like
  • Dislike Comment: DELETE http://localhost:8080/api/v1/blogs/{blog-id}/comments/{comment-id}/dislike

Technical Stack

• Backend Framework: Spring Boot
• Data Persistence: Spring JPA (Java Persistence API)
• Security: Spring Security with JWT for authentication and authorization
• Database: PostgreSQL
• Utilities: Lombok for reducing boilerplate code
• Pagination: Implemented across various endpoints to manage large data sets efficiently
