This app if for reservation services. I used the followig components for:

• Authentication microservice to authentcation incoming reuqests and check authorization.
• User Database which is mariaDB and it is used for storing user data
• Reservation microservice is used to reserve rooms based on user bonus
• Rooms Database which is mariaDB and it is used for storing room data and reservation status
• Nginx as an API Gatway
• rabbitMQ as a messging system to send notification from reservation microservice to reservationStatus queue.

Prerequests

• npm 5.6.0
• node 8.10.0
• docker 18.06.1-ce
• docker-compose 1.22.0

How To run This Project

• For the first time :
  • This will create microservices database and will install all the packages for all microservices and then it will run all the containers using docker-compose up command

  sh build.sh
  

  • If this not your first time to run the project use docker-compose up command

Assumptions

• This project will run on linux environment

How It Works

First of all you need to add to your headers apiSecret with its value 5V3TRE9-W3K4P99-HYCTGX9-VRBFVAL . The following examples are how to use reservation API endpoints.

• GET http://localhost/reservation/api/available-rooms is returning all available-rooms
• POST http://localhost/reservation/api/reserve-room will reserve room there is any available rooms. You must add this payload in your body request:

{
	
	"room_id":1,
	"user_id":2
}

This will reserve room_id (1) for user_id (2)

If he/she has enough bonus points, the status of this room <-> user relation changes to "RESERVED" and bonus points are subtracted. If he/she does not have enough bonus points, the status changes to “PENDING_APPROVAL”

Testing

• Every microserice has it owns unit tests
• to run unit tests for reservation, go to reservation folder and run

npm test

• to run unit tests for authentication, go to authentication folder and run

npm test

Container Integration

• I used Jenkins to setup CI

Enhancements

• error Handling
• more eslint rules
• Add environment variables
