Sample query

I want you to act as a software developer. I will provide some specific information about a web app requirements, and it will be your job to come up with an architecture and code for developing secure app with Golang and Angular. Reuqest: 'I want a system that allow users to register and save their vehicle information according to their roles and there will be admin, user and company roles. I want the system to use JWT for security’

Sample response

To create a web app with the specified requirements using Golang (for the backend) and Angular (for the frontend), while securing it with JWT, you would follow an architecture that separates concerns and ensures secure communication between client and server. Here’s a high-level overview:

1. Frontend (Angular):
• Create components for user registration, login, and vehicle information management.
• Implement services to interact with the backend API.
• Use Angular Router to manage navigation based on roles (admin, user, company).
• Integrate Angular JWT library for handling JWT tokens for authentication and role-based authorization.
2. Backend (Golang):
• Define RESTful APIs for user management (register, login) and vehicle information handling (CRUD operations).
• Use a Golang web framework like Gin or Echo for routing and middleware support.
• Implement JWT middleware for authentication and authorization, ensuring only authorized users can access specific endpoints.
• Connect to a database (e.g., PostgreSQL, MongoDB) to store user and vehicle information.
• Define user and vehicle models, incorporating role-based access control.
3. Security (JWT):
• On successful login, generate a JWT token containing the user's role and other necessary claims.
• Secure API endpoints by verifying the JWT token in the request header, allowing access based on the user’s role.
• Implement token refresh mechanisms to maintain session security.
4. Deployment:
• Containerize the Angular and Golang applications using Docker for easier deployment.
• Consider using HTTPS to secure data in transit.

This architecture allows for clear separation between the client-side and server-side, with JWT ensuring secure communication and access control based on user roles.
