Project Planning

Project Plan

A detailed timeline with key milestones including initial setup, front-end and back-end development, testing, and deployment.

Tools and Technologies

• Front-End: Next.js, Tailwind CSS
• Back-End: Node.js, Express
• Database: MongoDB, Mongoose
• Authentication: NextAuth, bcrypt

Risk Management

• Identified Risks:

  • Delays in development
  • Integration issues
  • Security vulnerabilities

• Mitigation Strategies:

  • Regular progress checks
  • Thorough testing
  • Secure coding practices

Requirements Analysis

Functional Requirements

• User registration and authentication
• Auction item creation, viewing, updating, and deleting
• Bidding on auction items
• Viewing current highest bid and bid history
• Notifications for outbid users

Non-Functional Requirements

• Responsive and user-friendly UI
• Secure handling of user data
• Efficient database queries and operations

System Design

Architecture

The application follows a Model-View-Controller (MVC) architecture to ensure a clear separation of concerns and enhance modularity.

Database Design

Uses MongoDB to store information about users, auction items, and bids. Managed via schemas/models using Mongoose.

ER Diagram

• Users: { userId, username, email, password }
• Auction Items: { itemId, title, description, startingBid, currentHighestBid, bidHistory, endDate, userId }
• Bids: { bidId, itemId, userId, bidAmount, bidTime }

Implementation

Technologies Used

• Next.js: Server-side rendering and static site generation.
• TailwindCSS: Utility-first CSS framework.
• MongoDB: NoSQL database.
• NextAuth: Authentication library using JWT.
• Node.js with Express: Backend framework for building RESTful APIs.

Justification for Different Tech Stack

Next.js was chosen over React for its built-in server-side rendering features, improving performance and SEO. MongoDB's schema-less structure suits the dynamic and scalable data needs of the auction platform. NextAuth simplifies secure authentication implementation. TailwindCSS allows rapid and consistent styling.

Development Process

• Methodology: Agile methodology with iterative development and regular feedback.
• Tools: Git for version control.

Modules Developed

• User authentication (registration, login)
• Auction item management (CRUD operations)
• Bidding functionality

Testing

Test Plan

• Unit testing
• Integration testing
• System testing
• User acceptance testing

Test Cases

• Registration and login functionality
• CRUD operations for auction items
• Bidding process and notifications

Maintenance and Future Enhancements

Maintenance Plan

Regular updates, backups, and monitoring.

Future Enhancements

Adding features like auto-bidding, advanced search and filtering, and recommendation systems.
