The Book Publishing and Paper Publication System is a serverless full-stack application that transforms the traditional publishing workflow into an efficient, collaborative, and scalable digital platform. It is designed to cater to the unique needs of the Sri Lankan publishing industry while leveraging global best practices.

• Real-time Collaboration: Authors, editors, and reviewers can work together on manuscripts.
• Automated Workflows: ISBN generation, cover design submission, and more.
• Scalable Architecture: Supports a growing user base with serverless backend solutions.
• Integrated Feedback System: Readers can review and rate published books.

The Sri Lankan publishing industry faces challenges such as limited collaboration tools, manual processes, and lack of automation in obtaining ISBNs and managing publications. This system addresses these pain points by:

1. Simplifying ISBN Applications:
   • Integrates with Sri Lanka's National Library and Documentation Services Board (NLDSB) for streamlined ISBN management.
2. Improving Collaboration:
   • Real-time manuscript editing reduces delays in publishing.
3. Ensuring Security:
   • Secures sensitive data such as book manuscripts and author contracts with advanced encryption.
4. Expanding Accessibility:
   • Provides multilingual support to cater to Sri Lanka's diverse population.

• Collaborate Effectively: Use the platform's real-time editing tools to work seamlessly with editors.
• Focus on Quality: Upload manuscripts only after thorough proofreading.

• Write Clean Code: Follow modular design principles, especially for microservices.
• Automate Testing: Use GitHub Actions to run tests on every pull request.
• Document APIs: Use tools like Swagger to ensure API documentation is comprehensive and up-to-date.

• Optimize Distribution: Use integrated analytics to identify high-demand books and target specific regions.
• Leverage Cloud Services: Utilize S3 storage for efficient and secure handling of digital assets.

1. User Management:
   • Role-based access control.
   • Profile and account management.
2. Manuscript Management:
   • Secure uploads with version history.
   • Real-time collaborative editing.
3. Publishing Workflow:
   • Automated ISBN assignment.
   • Seamless cover design and validation.
4. Distribution Tools:
   • Track book distribution to bookstores and e-commerce platforms.
5. Monitoring & Analytics:
   • Visualize system performance and user behavior with Grafana.

• Frontend: Hosted on AWS Amplify with static site optimization.
• Backend: Serverless Lambda functions, integrated with API Gateway.
• Database: RDS for relational data storage with auto-scaling.
• Storage: S3 for file storage with access restrictions.

1. User Auth Service:
   • Handles login, registration, and account upgrades.
2. Book Service:
   • Manages manuscript uploads and ISBN assignments.
3. Media Service:
   • Secure handling of ISBN certificates and cover designs.
4. Feedback & Buying Service:
   • Integrated with payment gateways and user review systems.

This documentation outlines a modular microservices architecture implemented using a Serverless Full-Stack approach with AWS services. It provides detailed explanations of each service, repository structure, and deployment practices, highlighting the stack used and its free-tier benefits.

Name: UserAuthService

Manages user authentication and authorization, ensuring secure access to the system. Includes features for profile management, account upgrades, and role-based permissions.

• Authentication: Sign-up, sign-in, and password recovery.
• User Management: Profile updates and account upgrades.
• Role Management: Different roles such as Author, Editor, and Admin.

• Frontend: Next.js with AWS Amplify for seamless API integration.
• Backend: AWS Lambda with Node.js and Express.js.
• Database: AWS RDS (PostgreSQL).

• POST /auth/signup
• POST /auth/login
• GET /auth/profile
• PUT /auth/upgrade

• user-auth-service

Name: BookService

Handles all operations related to books, including manuscript uploads, ISBN certificates, cover design submissions, and the publishing workflow.

• Manuscript Management: Secure uploads and versioning.
• Publishing Workflow: Prepares print-ready files and tracks publishing status.
• Buying and Feedback: Allows users to purchase books and provide feedback.

• Manuscript Upload Service

  • Handles uploads and version tracking of manuscripts.
  • Integrates AWS S3 for storage.

• ISBN & Cover Service

  • Uploads ISBN certificates and cover designs securely.
  • Prevents unauthorized access using AWS Lambda.

• Frontend: Next.js.
• Backend: AWS Lambda with Node.js + Express.js.
• Database: AWS RDS (PostgreSQL).

• POST /manuscripts/upload
• POST /isbn/upload
• POST /cover/upload
• POST /publish
• GET /books/:id

• book-service

Name: MediaService

Ensures secure forwarding of ISBN certificates and cover designs to prevent unauthorized access or hacking attempts.

• Uses AWS Lambda for processing and validating media files.
• Forwards files securely to downstream services.
• Logs and monitors media service activities with CloudWatch.

• Backend: AWS Lambda.
• Storage: AWS S3.

• POST /media/forward

• media-service

• Purpose:

  • Logs application activities and monitors service health.
  • Visualizes metrics like API response times and error rates.

• Implementation:

  • CloudWatch: Tracks logs and metrics for AWS services.
  • Prometheus: Monitors system health and integrates with Grafana for reporting.
  • Grafana: Creates dashboards for visualizing service performance.

• Implementation:

  • Preferred Option: AWS API Gateway for routing requests to Lambda functions.
