Usage
In some cases there will be a need for specialized functionality.
Using codeunits you use all of the existing nocode features, and just do the special features in custom code.
The platform will handle WHEN to execute the code, while you make the code do WHAT you want.
Note that custom extensions are loaded dynamically, so the platform can still be updated independntly of your custom code.
Many extension points
Your custom code can be plugged into various ponts
Pages
A page will display file or HTML content, with or without navigation wrapped around it.
Normal pages will only be served to authenticated users, while the public variant can be served to anyone accessing the URL.
Link via: URL (example: main?command=xxx)
Event handlers
An eventhandler will extend the behavior of an existing entity.
Multiple function handles ensure your code can be executed at the right time: beforeSelect, beforeRender, beforeUpdate etc.
In addition it is also possible control navigation flow after updates or build custom permission schemes (see below).
