eBookings POC

Project lear and test SpringBoot && Angular.

• Rest CRUD
• H2 in memory database
• RabbitMQ with Exchange's and Queue's
• FrontEnd in angular

Instalation

1. checkout repository
2. build java modules (see commands list)
3. run docker-compose to build and start containers (see commands list)

Commands list

1.Build java modules

# make provided script executeble
chmod +x ./build.sh

#run provided script
./build.sh

2. Docker compose

# build all containers managed by compose
docker-compose  -f docker-compose.yml build 

# start all containers managed by compose
docker-compose  -f docker-compose.yml up

# stop all containers managed by compose
docker-compose  -f docker-compose.yml down

Playground

• Frontend: http://localhost:8080
• H2 Console: http://localhost:8081/h2-console
  • driver: jdbc:h2:mem:test
• Rabbit Web Interface: http://localhost:15672/

other ports and services

• Rabbit listener: http://localhost:5672

Design

1. Backend, with Spring Boot

   • two micro-server's
     1. CORE -
        • Rest api for CRUD (server side pagination, sort, filter),
        • H2DB
        • consumers of RabbitMQ
        • create and populate H2 on init
        • configure Rabbit exchanges and queue's on init
     2. PRODUCER -
        • Rest api to receive request's
        • RabbitMQ producer to publish to Rabbit Exchange

2. RabbitMQ Configuration

   • MainExchange (producer will publish to this exchange)
     1. BookingExchange
     2. Audit Queue
   • BookingExchange will forward to delete, edit and create queue's, based on routing keys

3. Frontend, in Angular

   • Home page (user can select with protocol to use for delete/edit/create)
   • Table for listing
     • Paging
     • Sorting
     • Filter
     • store/state management (akita)
   • Page for editing (accessible from table), with actions:
     • update
     • delete
     • clone
   • Page for creating (accessible form navbar).
   • Akita as store/state management
