Example Model Server Instance
This package provides an example of how to configure an instance of the Model Server with plug-ins using the server framework.
Setup
See the parent readme for details of how to set up and build the project.
How to Run
This section provides a walk-through of the steps to launch the example Model Server instance.
Launch The Upstream Model Server
The node.js server is a customization layer in front of an instance of the Java Model Server, referred to in the server architecture as the Upstream Model Server. It provides the EMF-based management of resources and most of the API endpoints that are just forwarded by the node.js layer.
Open an Eclipse workspace on the Java projects in the eclipse-emfcloud/emfcloud-modelserver repository.
Be sure to import the projects from the /examples/ tree as well as /bundles/.
Edit the ExampleServerLauncher launch configuration in Eclipse, adding -p 8081 to the Program Arguments.
Then launch this configuration to start the Model Server, in this context filling the role of Upstream Model Server.
The server will start listening on port 8081 and its workspace will be initialized to the /examples/org.eclipse.emfcloud.modelserver.example/src/main/resources/workspace/ directory.
This workspace contains a minimal example Coffee model SuperBrewer3000.coffee.
Launch the Model Server node.js Layer
In the root of this repository, start the Model Server server via
$ yarn start
