Product Requirement Document (PRD)<\/h1>\n\n\n\n

1. Project Overview<\/h2>\n\n\n\n

The Product CRUD API<\/strong> is a simple RESTful web service built using Node.js and Express.js. It allows users to perform Create, Read, Update, and Delete (CRUD) operations on a collection of products.<\/p>\n\n\n\n

2. Purpose<\/h2>\n\n\n\n

The goal of this project is to provide a foundational backend API that can manage product data. It can later be integrated with a frontend dashboard or connected to a database such as MySQL.<\/p>\n\n\n\n

3. Scope<\/h2>\n\n\n\n

The system will:<\/p>\n\n\n\n

  • Allow users to add new products<\/li>
  • Retrieve all or specific products<\/li>
  • Update existing products<\/li>
  • Delete products from the list<\/li><\/ul>\n\n\n\n

    4. Functional Requirements<\/h2>\n\n\n\n

    4.1 Product Entity<\/h3>\n\n\n\n

    Each product contains the following fields:<\/p>\n\n\n\n

    Field<\/th>Type<\/th>Description<\/th><\/tr><\/thead>
    id<\/td>Integer<\/td>Unique identifier for each product<\/td><\/tr>
    title<\/td>String<\/td>Name or title of the product<\/td><\/tr>
    price<\/td>Number<\/td>Product price in currency value<\/td><\/tr>
    stock<\/td>Number<\/td>Quantity of product available in inventory<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

    4.2 API Endpoints<\/h3>\n\n\n\n
    Method<\/th>Endpoint<\/th>Description<\/th><\/tr><\/thead>
    GET<\/td>\/products<\/td>Fetch all products<\/td><\/tr>
    GET<\/td>\/products\/:id<\/td>Fetch single product by ID<\/td><\/tr>
    POST<\/td>\/products<\/td>Create new product<\/td><\/tr>
    PUT<\/td>\/products\/:id<\/td>Update existing product<\/td><\/tr>
    DELETE<\/td>\/products\/:id<\/td>Delete a product<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

    4.3 Request\/Response Examples<\/h3>\n\n\n\n

    POST \/products<\/strong><\/p>\n\n\n\n

    {\n  \"title\": \"Keyboard\",\n  \"price\": 1200,\n  \"stock\": 50\n}<\/code><\/pre>\n\n\n\n
    Response:<\/strong><\/p>\n\n\n\n
    {\n  \"id\": 3,\n  \"title\": \"Keyboard\",\n  \"price\": 1200,\n  \"stock\": 50\n}<\/code><\/pre>\n\n\n\n
    PUT \/products\/3<\/strong><\/p>\n\n\n\n
    {\n  \"price\": 1000,\n  \"stock\": 60\n}<\/code><\/pre>\n\n\n\n
    5. Non-Functional Requirements<\/h2>\n\n\n\n
    • Scalability:<\/strong> Can later be integrated with a database.<\/li>
    • Performance:<\/strong> Should handle up to 1000 requests per second on local tests.<\/li>
    • Security:<\/strong> Input validation required for all API calls.<\/li>
    • Maintainability:<\/strong> Code follows modular and RESTful design principles.<\/li><\/ul>\n\n\n\n
      6. Technology Stack<\/h2>\n\n\n\n
      Component<\/th>Technology<\/th><\/tr><\/thead>
      Backend<\/td>Node.js<\/td><\/tr>
      Framework<\/td>Express.js<\/td><\/tr>
      Database (Future)<\/td>MySQL<\/td><\/tr>
      Tools<\/td>Postman for testing, npm for dependency management<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n
      7. Assumptions<\/h2>\n\n\n\n
      • The system will initially store data in-memory.<\/li>
      • The id<\/code> field auto-increments based on the existing array size.<\/li>
      • No user authentication is implemented at this stage.<\/li><\/ul>\n\n\n\n
        8. Future Enhancements<\/h2>\n\n\n\n
        • Integrate with persistent storage (MySQL or MongoDB)<\/li>
        • Add authentication and authorization<\/li>
        • Implement pagination and search filters<\/li>
        • Include product image uploads<\/li><\/ul>\n\n\n\n
          9. Deliverables<\/h2>\n\n\n\n
          • Node.js Express application (server.js<\/code>)<\/li>
          • Postman collection for API testing<\/li>
          • Documentation (this PRD)<\/li><\/ul>\n","protected":false},"excerpt":{"rendered":"
