jsUML2: Open-Source JS Library for Browser UML Diagrams
jsUML2 is an open-source JavaScript library for generating UML diagrams in the browser. It allows users to create class, use case, activity, sequence, and state diagrams using simple JavaScript code.
What is JsUML2?
jsUML2 is an open-source JavaScript library for creating UML diagrams directly in the browser. It was originally developed by Zbigniew Skuzinski and since 2019 has been maintained by Ian Chamberlain.
Some key features of jsUML2 include:
- Supports all major UML diagram types: class, object, use case, component, deployment, composite structure, activity, state machine, communication, interaction, timing, and profile diagrams
- Pure JavaScript implementation, no dependencies required
- Renders diagrams using SVG for good printing support and responsiveness
- Exposes simple API for programmatically generating diagrams with JavaScript/TypeScript code
- Extendable and customizable designs and themes
- Open source (MIT license) with active development on GitHub
jsUML2 allows developers to visualize and document the structure and behavior of software systems without needing to use heavy desktop applications. Because it runs in the browser, diagrams can easily be integrated into web applications and documentation. An active community provides themes, examples, and support to help new users get started.
