Load GeoJson Map to capabilities.json

Regarding the first question you should follow these steps:

• Take a look at this topic to find out more about JS File API
• Define a text property at capabilities.json

"objects": {
    "internalState": {
        "displayName": "Internal State",
        "properties": {
            "geojsonMap": {
                "displayName": "geojsonMap",
                "type": {
                    "text": true
                }
            }
        }
    }
}

• Call persistProperties method of host

function save(host: IVisualHost, value: string) {
    host.persistProperties(<VisualObjectInstancesToPersist>{
        merge: [{
            objectName: "internalState",
            selector: null,
            properties: {
                geojsonMap: value || ""
            }
        }]
    });
}

Regarding the second question.

You should prepare type definitions for you function. Another way is to use TS file instead of JS.
