Building an Online Cab Booking System | A Full-Stack Web Application Using .NET Core & Angular

🧩 Introduction

In today’s fast-paced digital world, cab services like Ola and Uber have become essential for daily commuting. As part of my software development journey, I built an Online Cab Booking System to simulate such real-time applications. This project integrates .NET Core 6, ASP.NET Web API, Entity Framework Core, Angular, and SQL Server, forming a robust full-stack web application.

This blog walks you through the architecture, features, technologies, and learning outcomes of the project.

🎯 Project Goals

The primary goal of this system is to streamline the process of booking cabs online through a web-based application. The project caters to three main user roles:

• Customer – Can book cabs, check booking status, and view ride history.

• Admin – Manages users, employees, cabs, and bookings.

• Employee/Driver – Assigned to bookings and updates ride status.

This project is ideal for understanding CRUD operations, role-based access control, REST API consumption, and full-stack development patterns.

🏗️ System Architecture

The application is built using the client-server model with a clear separation of concerns.

• Frontend: Developed using Angular (TypeScript), hosted separately.

• Backend: Built on .NET 6 Web API Core with RESTful endpoints.

• Database: Managed through SQL Server using Entity Framework Core ORM.

• Development Tools: Visual Studio 2022 (backend) and VS Code (frontend).

🧰 Technologies Used

Layer	Technologies
Frontend	Angular 16, HTML, CSS, TypeScript
Backend	.NET 6, ASP.NET Web API Core
Database	SQL Server 2019
ORM	Entity Framework Core
IDEs	Visual Studio 2022, VS Code
Tools	Postman, SSMS, GitHub

🧱 Modules and Key Features

🔐 Admin Panel

• Add, update, or delete:

  • Customers

  • Employees

  • Cab details

• View and manage all bookings

• Remove or update employee records

• View user feedback

👤 Customer Panel

• Register/login

• Book a cab (select pickup/drop locations, type of cab)

• View booking status (pending, confirmed, completed)

• Access booking history

• Submit feedback

👷 Employee/Driver Module

• View assigned bookings

• Update ride status (accepted, on the way, completed)

🧪 Key Functionalities Implemented

• JWT-based authentication and token management

• Role-based access control (Admin vs Customer vs Driver)

• RESTful API integration with Angular

• Database relationships using EF Core (One-to-Many: Employee → Booking)

• Dynamic dropdowns for cab selection

• Status update with conditional logic

🚧 Challenges Faced

🔄 Backend-Frontend Sync

Ensuring the Angular frontend correctly consumed .NET APIs required careful mapping and error handling. I used Postman to verify every endpoint before integrating.

🧵 Status Management

Managing booking states (Pending, Confirmed, Cancelled, Completed) across modules was tricky. I used an enum in .NET and Angular constants to keep both layers consistent.

🔐 Secure Access

Role-based restrictions were implemented to ensure that customers couldn't access admin routes and vice versa.

🌱 What I Learned

This project helped me strengthen my understanding of:

• End-to-end full-stack development

• REST API design and consumption

• Angular service-based architecture

• Secure authentication with JWT

• Database normalization and foreign key relationships

• Project structure and modular coding

🚀 Future Enhancements

Here’s what can be added next:

• ✅ Real-time booking tracking (via SignalR or WebSocket)

• 💳 Payment gateway integration

• 📱 Mobile-responsive UI or mobile app version

• 📍 Google Maps API for location tracking

• 📅 Schedule bookings in advance

📌 Conclusion

Creating an Online Cab Booking System was a challenging yet rewarding experience. It provided hands-on exposure to real-world software architecture, user management, and full-stack development using modern technologies.

This kind of project not only sharpens technical skills but also demonstrates problem-solving and system design thinking — key qualities in any software development role.
