diagrams.net, previously draw.io, is an online diagramming web site that delivers the source in this project.
diagrams.net uses the mxGraph library as the base of the stack, with the GraphEditor example from mxGraph as the base of the application part. The mxGraph library build used is stored under /etc/mxgraph/mxClient.js.
diagrams.net is licensed under the Apache v2.
A development guide is being started on the GitHub project wiki. There is a draw.io tag on Stack Overflow currently, please make sure any questions adhere to their guidelines for questions.
The mxGraph documentation provides a lot of the docs for the bottom part of the stack. There is an mxgraph tag on SO.
One way to run diagrams.net is to fork this project, publish the master branch to GitHub pages and the pages sites will have the full editor functionality (sans the integrations).
Another way is to use the recommended Docker project or to download draw.io Desktop.
The full packaged .war of the client and servlets is built when the project is tagged and available on the releases page.
