Developing UI5 Controls in JavaScript

For developing controls for SAPUI5 in JavaScript, it is either possible to extend existing controls or to create new controls on the fly, so-called notepad controls.

For notepad controls, a library definition or running generation steps is not necessary.

When several controls should be developed for reuse in different applications, we recommend to create a control library instead of using these notepad controls. Control libraries have additional features like automatic support for theming and right-to-left languages, but the implementation of the controls is the same as for notepad controls.
