Docker needs to be installed in the machine.
"docker-compose up" should start up the angular and Spring boot applications.
And opening the url http://localhost (using docker-desktop) or 192.168. 99.100 (using docker-toolbox).
If any issue arises due to port. Changing the port in docker-compose.yml (line 6) should be sufficient.
transaction-ui Contains the Angular 8 code. Bootstrap, NGRX, RxJs, Ag-grid.
Ag-grid is used to both generate the table in the UI and to export the contents as csv.
Docker image runs with nginx server and statically hosted files of angular from dist folder of ng build output.
Nginx does the reverse proxy of the services using nginx.conf
Karma and Jasmine for unit testing.
transaction-service
Built using spring boot. Spring data jpa (to fetch the database values using Example.of).
It connects to embedded h2 database. H2 console is also enabled.
At the startup, the Spring batch reads the data line by line and inserts in the database.
The reason for using spring batch is because, it helps in loading large dataset and it can be integrated with quarts or any other frameworks to run at certain time.
Lombok is used to make the model classes and logging simplified.
Include cucumber to do integration tests with urls.
Add JenkinsFile and test in Jenkins.
Needs to do server side generation of CSV files for high datasets.
Feed the data using Kafka to spring boot and integrate it with Spring cloud streams.
If more services are added, API gatway like zuul is required and code can be movied to Kubernetes.
Authentication and authorization can be added using OAUTH2 static scanning and dynamic scanning can be added for application security and make it follow OWASP Standards.
