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
