Advanced development

The chapters below describe the parts of Hubleto ERP that you touch when the standard app is not enough: the core classes, the data layer, the user interface and the system services. Read the Apps chapter first. It contains everything that is needed to build an app. This chapter goes deeper.

Core architecture	Layers, extension points, dependency injection, users and authentication.
