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.

• 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

Only the good ones (those that support SVG):

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

If you want to work on JointJS locally, use the following guidelines to get started.

Make sure you have the following dependencies installed on your system:

• Node.js
• grunt-cli
• bower
• git

Clone this git repository:

git clone https://github.com/clientIO/joint.git

Change into the joint directory:

cd joint

Run installation

npm install
bower install

This will install all npm and bower dependencies as well as run a full build.

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 test:code-style

To output a code coverage report in lcov format for all unit tests:

grunt test:coverage --reporter="lcov"

The output will be saved to a new file named coverage.info at the root of the project directory.

The dist directory contains pre-built distribution files. To re-build them, run the following:

grunt dist

The source for the JointJS documentation (plus geometry and Vectorizer libraries) are included in this repository; see the docs directory. The documentation can be built into stand-alone HTML documents like this:

grunt build:docs

The output of the above command can be found at build/docs.
