🚀 Quick Start

1) Prerequisites

• .NET 9 SDK
• Node.js 18+ & npm
• Angular CLI (npm i -g @angular/cli)
• PostgreSQL 14+

2) Clone & Restore

 git clone https://github.com/Belal-uddin/Bus-Ticket-Reservation-System.git
 cd BusBook

# Restore .NET deps
 dotnet restore

# Install Angular deps
 cd src/client
 npm install
 cd ../..

3) Configure database

Create a PostgreSQL database (e.g., busbook_db). Then set the connection string in src/WebApi/appsettings.Development.json:

{
  "ConnectionStrings": {
    "DefaultConnection": "Host=localhost;Port=5432;Database=busbook_db;Username=postgres;Password=postgres"
  }
}

4) Apply EF Core migrations

# From repository root
 dotnet tool update --global dotnet-ef

 # Ensure Infrastructure is the migrations assembly and WebApi is startup
 dotnet ef database update -p src/Infrastructure -s src/WebApi

5) Run the API

cd src/WebApi
 dotnet run
# API runs on https://localhost:5001 (or shown port)

6) Run the Angular app

cd src/client
# Set the API base URL in src/environments/environment.ts
# Example:
# export const environment = { apiUrl: 'https://localhost:5001' };

 ng serve --open

🧪 Tests

# From repository root
 dotnet test
