====== Architecture ======

{{tag>frontend architecture}}

The application is divided into 2 technological lines: backend (java) and frontend (javascript). There is a REST interface between the two.


===== Minimum executable application =====

The minimal executable application always contains the app + core modules.

==== Core module ====

Contains services, managers, components and individual core pages. More in [[.modularity|modularity]] and in the next chapter with layers.

==== App module ====

= Application, executable application. Connects modules with environment configuration. 


===== Modularity =====

<note important>TODO: Introduction</note>


==== Installation/ module update ====

Installation/ module update is done by copying the module into the application libraries **<idm.war>/WEB-INF/lib**. Modules can also be included directly in the project dependencies (pom.xml modul app).

You can see a list of all installed modules and their status (enabled/disabled) in the Modules agenda in the Settings. 

Modules can be enabled/disabled by setting **idm.pub.<identificator__of_module>.enabled** as true, or false. 


==== Module-specific database scripts ====

Each module can contain its own set of [[.flyway|database scripts]], which are applied to the application database scheme at the start of the application (in the phase after initializing the data connection, or rather after initializing the hibernate context) => **the modules are automatically initializing and updating the database scheme themselves.**


==== Example module ====

The [[https://github.com/bcvsolutions/CzechIdMng/tree/master/Realization/backend/example|example module]] was created for module demonstration and, at the same time, as a template (skeleton) for creating a module with pre-filled configurations.
