Backend System  Overview

1. Authentication and Authorization

Integration with Firebase Admin: Implement backend services using Firebase Admin SDK to manage users, roles, and permissions.

Role-Based Authentication: Define four distinct roles: Admin, Vendor, Client, and Driver.

Advanced Middleware: Create middleware functions to verify user roles and enforce access control for protected routes.

2. User Management

Registration and Profiles: Enable registration for different user roles, each with a unique set of data fields and validation rules.

Implement JSON Web Tokens (JWT) for secure, token-based user authentication.

Use password encryption techniques (such as bcrypt) to ensure the safety of user credentials.

User CRUD Operations: Allow for adding, updating, and retrieving user information.

Address Management: Provide functionality for users to add, update, and retrieve addresses.

Implement logic to maintain a single default address per user, with the ability to change the default setting.

3. Vendor-Specific Features

Vendor Registration: Set up a registration process for vendors, including the collection of necessary information and validation.

Vendor Middleware: Ensure that only vendors can access routes for managing their restaurant and food items.

Food Management: Develop endpoints for vendors to upload and manage their food items.

4. Recommendations and Dynamic Content

Location-Based Restaurant Recommendations: Create endpoints that suggest restaurants to clients based on their current location.

Dynamic Food Recommendations: Develop algorithms to recommend food items to users also based on user location.

Preparation and Delivery Time: Introduce logic to recommend food that can be prepared and delivered in the shortest possible time, considering user location.

5. Shopping Cart and Order Processing

Cart Management: Allow users to add and remove items from the cart.

Enable users to adjust the quantity of cart items.

Update and return the cart count whenever changes are made to the cart.

Order Creation and Management: Provide functionality for users to create orders and customize them with add-ons.

Update orders based on payment and delivery status.

6. Categories and Recommendations

Category Management: Allow admins to add, update, and delete categories of food.

Category Recommendations: Use aggregation pipelines to offer random category recommendations to users.

7. Driver-Specific Functionality

Driver Registration and Restrictions: Establish registration for drivers and ensure middleware restricts them to driver-related tasks.
