Online Fast Food App

An ASP.NET Core application mimicing the features of Just Eat, the online restaurant and delivery platform.

Getting Started

Prerequisites

Requirements to build and run the project locally.

• Docker

Or if you don't want to use docker:

• .NET 8
• SQL Server 2022
• Node.js

Usage

• Start the frontend and API server:

docker compose up

• Stop the app:

docker compose down

Visit http://localhost:3000 for the frontend.

Visit http://localhost:8080/swagger for the REST API documentation, and a UI for running some authenticated requests. The API runs at http://localhost:8080/api.

Features

Split into user facing and software implementation features (frameworks used, design etc.)

User Functionality

• Delivery system

  • Uses a dedicated delivery driver role
  • Driver rating by users
  • Tracking and arrival time estimation using location
  • Nearest driver to the restaurant selected at order time

• User recommendations

  • Recommends products and restaurants based on categorical similarity with order history
  • Also uses frequently ordered at restaurants / bought products
  • Globally trending products / local restaurants since last week

• Online basket

  • List of items before ordering
  • Coupons applied at checkout

• Locations

  • Users, Delivery drivers and restaurants have locations
  • For finding nearby restaurants, estimating delivery time, and selecting a nearby driver

• Partner role

  • The restaurant owner role
  • Get restaurant revenue
  • Manages menu products

Software Implementation

• Entity framework core
  • Abstracts database relationships, removing the need for a foreign key in code
  • Use indexing to ensure efficient querying based on use case
• ASP.NET Identity
  • JWT authentication, a lightweight solution. Stores user ID in payload.
  • Resource-base authorization (using policies) to restrict access to data using business logic.
  • Role-based authorization (User, Partner, DeliveryDriver, Admin).
• Useful Patterns
  • Repository for data access
  • Service for business logic without data access
  • Unit of work for multiple database updates
• ASP.NET Web API
  • API endpoint routing, and status code handling

API Overview

Extra features

Other interesting features I could add in the future:

• Group ordering for multiple users to place one order together, and pay once.
• Automatically adjusting menu pricing based on recent demand, to maximize revenue.
• Contextual recommendations based on the time of day, user's location, active discouns/promotions.
