Movie Reservation System

A simple backend service in Go for managing movies, showtimes and seat reservations.

Features

• User signup, login and role-based access via JWT
• CRUD operations for movies (admin only)
• CRUD operations for showtimes (admin only)
• List movies and their showtimes
• Check available seats and make/cancel reservations

Prerequisites

• Go 1.21 or higher
• PostgreSQL database

Setup

1. Clone the repository:

   git clone <repository-url>
   cd ticketmonster

2. Copy .env.example to .env and update settings.
3. Install dependencies:

   go mod tidy

4. Start the application locally:

   go run cmd/main.go

The server listens by default on :8080.

Docker

To run both the API and a PostgreSQL database with Docker:

docker-compose up -d

This will build the Go binary, start the service on port 8080, and spin up Postgres on port 5432 (database movie_reservation is created automatically).

To connect to the DB container or recreate the database manually:

docker-compose exec db createdb --username=postgres movie_reservation

Stop and remove containers:

docker-compose down
