jsplumb / jsPlumb


Visual connectivity for webapps



jsPlumb provides a means for a developer to visually connect elements on their web pages. It uses SVG and runs on all browsers from IE9 and later.

The final version of jsPlumb to support IE8 was 1.7.10. You can still get 1.7.10 from a tag, if you need it.

If you're new to jsPlumb, please do take the time to read the documentation. There are a few integration issues that you should be aware of: z-index needs special attention, for example.

This project is the 'Community Edition' of jsPlumb. The 'Toolkit Edition' is a commercially-licensed wrapper around this.

This project is not the correct place to report issues for the Toolkit edition. The Toolkit is not a public project. Issues reported for the Toolkit edition in this issue tracker will be cleared.

Project Structure

At any time there is a built version in the dist directory, which contains the concatenated and minified files, as well as a full set of demos and tests, and there is a version under development in src. If taking something that is working and adapting it for your needs is what you want to do, use the files in the dist directory. If you need to work directly with the version in development - maybe there's a bug fix you need or whatever - you need the files in the src directory.

Note that the demos in the demos directory are always pointing at the current development version, and therefore have a long list of imports.


jsPlumb uses GitHub's issue tracker for enhancements and bugs. But please do check the Google Group before posting an issue, particularly if you're just asking a question.


No external dependencies.
