The OpenSource mORMot is a RESTful ORM / MVC / SOA framework for Delphi and FreePascal. Some of its codebase is now about 10 years old, and it was time to clean and evolve. This year 2020 triggered a deep refactoring of the whole source code, with a full rewrite of some core components (JSON, RTTI). This session will present the version 2 of mORMot it its current state, the principles behind this refactoring, and how you may find useful gems for your own Delphi applications.
