"Diagram interactions" Cockpit Plugin

This example shows how you can achieve diagram interactions with custom plugins. Click on an activity in the BPMN diagram to apply a filter to the table.

Built and tested against Camunda Platform version 7.22.0.

Diagram Interaction

To achieve diagram interaction, we will use 2 plugins scoped in one module. The first plugin registers at cockpit.processDefinition.diagram.plugin or another diagram plugin point and registers a listener on the viewer event bus. With the dispatched event we can call our own functions:

render: viewer => {
  viewer.get("eventBus").on("element.click", event => {
    if (event.element.type.includes("Task")) {
      cb(event.element);
    }
    // ...
  });
}

In the second plugin, we can create a callback function which the diagram plugin calls. In this example, we will apply a filter to a table depending on what task was clicked on.

  render: (node, { processDefinitionId }) => {
    // ...
    cb = el => {
      getUsertasks(el.id);
    };
  }

Integrate into Camunda Webapp

Copy the plugin.js file into the app/cockpit/scripts/ folder in your Camunda webapp distribution. For the Tomcat distribution, this would be server/apache-tomcat-X.X.XX/webapps/camunda/app/cockpit/scripts/.

Add the following content to the app/cockpit/scripts/config.js file:

// …
  customScripts: [
    'scripts/plugin.js'
  ]
// …

After that start the server, login to Cockpit and navigate to the process definition view to check the result.
