How to use the warp10.stringifyPrepare function in warp10

var state = renderedWidgets.state;
    var config = renderedWidgets.config;

    var result = {
        ids: ids
    };

    // NOTE: Calling warp10.stringifyPrepare(obj) will produce a new object that is safe to serializing using
    //       JSON.stringify(). The deserialized/parsed object will need to be converted to the final object using
    //       warp10.finalize(obj)
    if (!isObjectEmpty(state)) {
        result.state = warp10.stringifyPrepare(state);
    }

    if (!isObjectEmpty(config)) {
        result.config = warp10.stringifyPrepare(config);
    }

    return result;
};

exports.getRenderedWidgets = exports.getRenderedWidgetIds /* deprecated */ = function(widgetsContext) {
    var renderedWidgets = getRenderedWidgets(widgetsContext);
    var ids = renderedWidgets.ids;
    var state = renderedWidgets.state;
    var config = renderedWidgets.config;

    var result = {
        ids: ids
    };

    // NOTE: Calling warp10.stringifyPrepare(obj) will produce a new object that is safe to serializing using
    //       JSON.stringify(). The deserialized/parsed object will need to be converted to the final object using
    //       warp10.finalize(obj)
    if (!isObjectEmpty(state)) {
        result.state = warp10.stringifyPrepare(state);
    }

    if (!isObjectEmpty(config)) {
        result.config = warp10.stringifyPrepare(config);
    }

    return result;
};

exports.getRenderedComponents = function(out) {
    var renderedComponents = getRenderedComponents(out, true);
    return warp10.stringifyPrepare(renderedComponents);
};
