About

drawio-desktop is a diagrams.net desktop app based on Electron. draw.io is the old name for diagrams.net, we just don't want the hassle of changing all the binary's names.

Download built binaries from the releases section.

Security

draw.io Desktop is designed to be completely isolated from the Internet, apart from the update process. This checks github.com at startup for a newer version and downloads it from an AWS S3 bucket owned by Github. All JavaScript files are self-contained, the Content Security Policy forbids running remotely loaded JavaScript.

No diagram data is ever sent externally, nor do we send any analytics about app usage externally. This means certain functionality for which we do not have a JavaScript implementation do not work in the Desktop build, namely .vsd and Gliffy import.

Developing

draw.io is a git submodule of drawio-desktop. To get both you need to clone recursively:

git clone --recursive https://github.com/jgraph/drawio-desktop.git

To run this:

1. npm install (in the root directory of this repo)
2. npm install (in the drawio directory of this repo drawio/src/main/webapp)
3. export DRAWIO_ENV=dev if you want to develop/debug in dev mode.
4. npm start runs the app.

To release:

1. Update the draw.io sub-module and push the change. Add version tag before pushing to origin.
2. Wait for the builds to complete (https://travis-ci.org/jgraph/drawio-desktop and https://ci.appveyor.com/project/davidjgraph/drawio-desktop)
3. Go to https://github.com/jgraph/drawio-desktop/releases, edit the preview release.
4. Download the windows exe and windows portable, sign them using signtool sign /a /tr http://timestamp.globalsign.com/?signature=sha2 /td SHA256 c:/path/to/your/file.exe
5. Re-upload signed file as draw.io-windows-installer-x.y.z.exe and draw.io-windows-no-installer-x.y.z.exe
6. Add release notes
7. Publish release

Note: In Windows release, when using both x64 and is32 as arch, the result is one big file with both archs. This is why we split them.
