UML Diagrams IntelliJ Plugin for JavaScript and TypeScript

Provides support for UML class diagrams in IntelliJ-based IDEs for JavaScript and TypeScript languages. The following features are available:

• Support for JS and TS classes, interfaces and enums.
• Class members structure view with respect to the latest JS and TS standards.
• Diagrams editing: adding and removing nodes, drag-and-drop support.
• Show parents and implementations.

Usage:

It's possible to build a diagram from a single class or an interface, a JavaScript or a TypeScript file and from a whole directory. To create a diagram you could use an item called Diagrams in a context menu, and then select a JavaScript and TypeScript Classes diagram type.
