Please install all necessary prerequisites on your system.
For detailed instructions for a Windows machine, follow this guide.
yarn
yarn start:electron
or:
yarn rebuild:electron
cd applications/electron-app
yarn start
or: launch Launch CrossModel Electron configuration from VS code.
Under examples/verdaccio-example/workspace we provide an example workspace with some demo packages containing entities, relationships and system diagrams.
Each package represents a dedicated system or library and may depend on other packages.
Using a known package structure - npm in our case - we can re-use large parts of the package management to download dependencies that are not locally available from an external package registry. In order to test this behavior, we use verdaccio as a local npm registry that provides some models that are needed by our workspace packages. You can start verdaccio using
yarn start:verdaccio
The local npm registry will be available under http://localhost:4873/ where we already provide four packages by default.
After opening the workspace, you can install the necessary dependencies in the example workspace by opening a terminal in examples/verdaccio-example/workspace and execute
npm install
This should download all dependencies into dedicated node_modules directories within the workspace.
Currently there is still an issue where new files are not recognized automatically, so you need to reload your workspace once for all the dependencies to be properly recognized.
Start watching all packages, including electron-app, of your application with
yarn watch
or watch only specific packages with
cd packages/<package-name>
yarn watch
and the Electron example.
cd applications/electron-app
yarn watch
Run the example as described above.
Any code changes will be automatically detected and the application will be re-compiled.
If you only made changes to the frontend or plugins, simply reloading the running application with F5 is enough.
If you also made changes to the backend, you can close and restart the application without manual re-compilation.
You can work on CrossModel from within a Dev Container. The best way to do so is create a new Dev Container and cloning the repository in there. For instructions please consult this page.
Short steps:
- Install Docker with WSL 2 engine enabled.
- In VS Code press [CTRL] + [SHIFT] + [P] and type 'Dev Container: Clone Repository in Container Volume...' and press [Enter].
- Enter the current repository URL and press [Enter]. Now the dev container will be created with the Git repository cloned in it (faster then cloned locally in Windows).
To package the application use
yarn theia:electron package
Depending on the platform, this will produce an executable or an installer for the application under applications/electron-app/dist.
Details about the packaging can be configured in applications/electron-app/electron-builder.yml.
A general overview of the application architecture is provided in the Architecture Overview. The repository itself contains the following components structured as follows:

- mui-x : MUI X is open core—base components are MIT-licensed, while more advanced features require a Pro or Premium commercial license. We are currently only using core-base
- react-tabs: MIT
- chevrotain: This library is a dependency of langium. To get the Yaml language working in crossmodel an example implementation of the python language of chevrotain has been used. This example has been modified to make it work for the yaml language.
