PrimeTrade.ai - Backend Developer Intern Assignment

This repository contains the complete full-stack solution for the Backend Developer (Intern) assignment at Primetrade.ai. The project focuses on a scalable REST API with role-based access control, supported by a basic frontend UI to interact with the endpoints.

Tech Stack

Backend:

• Node.js & Express.js
• PostgreSQL (Database schema design & management)
• JSON Web Tokens (JWT) for secure authentication
• bcrypt for password hashing
• Swagger for API Documentation

Frontend:

• React.js / Vite[cite: 1]
• CSS / Tailwind (for simple UI)[cite: 1]

Core Features Implemented

Backend API Design

• Authentication: User registration and login APIs utilizing password hashing and JWT authentication[cite: 1].
• Authorization: Role-based access control distinguishing between regular users and admins[cite: 1].
• CRUD Operations: Complete Create, Read, Update, and Delete APIs for a secondary entity (e.g., tasks/products)[cite: 1].
• Robustness: Implemented API versioning, standard status codes, structured error handling, and input validation/sanitization[cite: 1].

Frontend Integration

• User Flows: Interfaces to register and log in users seamlessly[cite: 1].
• Protected Dashboard: Restricted access to the dashboard requiring a valid JWT[cite: 1].
• Entity Management: UI forms and tables to perform CRUD actions on the database entity[cite: 1].
• Feedback: Displays clear error and success messages based on API responses[cite: 1].
