Russian version

This service is to show specific banner for user depends on its feature and tag parameters. Also it is provided interface to manage banners, its content, tags and features.

The web application architecture include two main layers: Core and Infrastructure. Core is lower than Infrastructure, so code from Infrastructure can call code of Core but not vice versa. This also applies to internal layers components located vertically. And this reflects directories tree inside src.
As it can be seen, the Repository pattern applied here. The repository package contains IRepository interface that is used by application package which is presented the main logic. model package contains structures representing banners, features, tags and users. storage package includes PostgreSQL connector and implements IRepository interface to make possible its injection into application as a database. controllers package is API implementation which contains the logic for processing requests.

Application deploying is made with docker-compose. So it is necessary to have it installed before running. The service starting requires environment variables defined in .env file. The example of all necessary variables is in env-example file. It is reccomend to create file with these variables manualy. In case the .env is missing it will be created from env-example automatically at startup.
As it can be seen from env-example file, application will start on localhost:8080 and web adminer to manage PostgreSQL database on localhost:8888.
There are the next commands for Makefile allows to steer service running.

# run service and testing
make

# run testing (totally failed in case service is down)
make test

# run service
make run

# stop service
make stop

# stop and remove containers data (do not removes docker volume)
make clean
