Calling a component inside a script

To call a component inside a script, you need to use the context.component object which gives you references to components and their actions.

For example, to call logger component and its info action in javascript you can use the following code:

function perform(input, context) {
    context.component.logger.info({'text': 'Hello World!!!'})

  return null;
}

If you want to call an action of a component which requires a connection you can define its connection inside the Script editor:
