Architecture

Before you start

• Set up the connection to database in movie-service/src/config/db.js
• Set AMQP_URL variable in .env file (you can use a free 'Little Lemur' plan from CloudAMQP)

#start services
docker-compose up -d

#fill db with sample data 
docker exec -it <MOVIE_SERVICE_CONTAINER_NAME> node src/init

Features

• Browsing available movies at cinema

  Details of movies are fetched from external api's OMDb TMDb

  

  

• Buying tickets

  Orders are stored in local database

  

  

• Temporary reservations

  Reservations are implemented by using Socket.io (each movie has own room -> each client subscribe only room/movie event which is actually browsed) and stored in-memory on api-gateway. To improve api scalability on production, reservations should be stored in distributed DB like Redis

  

• Sending email with purchased ticket

  Using fake SMTP service Ethereal
