JointJS - JavaScript diagramming library

JointJS is a JavaScript diagramming library. It can be used to create either static diagrams or, and more importantly, fully interactive diagramming tools and application builders.

Please see http://jointjs.com for more information, demos and documentation.

Features

• basic diagram elements (rect, circle, ellipse, text, image, path)
• ready-to-use diagram elements of well-known diagrams (ERD, Org chart, FSA, UML, PN, DEVS, ...)
• custom diagram elements based on SVG or programmatically rendered
• interactive elements and links
• connecting diagram elements with links
• customizable links, their arrowheads and labels
• links smoothing (bezier interpolation)
• magnets (link connection points) can be placed basically anywhere
• hierarchical diagrams
• serialization/deserialization to/from JSON format
• highly event driven - you can react on any event that happens inside the paper
• zoom in/out
• touch support
• plugin awareness
• MVC architecture
• ... a lot more

Supported browsers

Only the good ones (those that support SVG):

• Latest Google Chrome (including mobile)
• Latest Firefox
• Safari (including mobile)
• IE 9+

Tests

Before running tests, be sure to run a full build:

grunt all

To run all tests:

grunt test

To run only the server-side tests:

grunt test:server

To run only the client-side tests:

grunt test:client

To run code style checks:

grunt jscs

Code Coverage

It is possible to generate code coverage reports using the existing qunit tests. For example, to output the coverage report in lcov format for the joint unit tests:

grunt qunit:joint --reporter lcov --coverage

And for all unit tests:

grunt qunit:all --reporter lcov --coverage

By default, the output will be saved to coverage.info at the root of the project directory. You can change the output file like this:

grunt qunit:joint --reporter lcov --output customfilename.info --coverage
