Node.JS Servicecallout Policy documentation

[michaelmcdowell]

Is there any examples describing how to use the Node.JS ServiceCallout policy option?

<ServiceCallout async="false" continueOnError="false" enabled="true" name="Token-Callout">
    <DisplayName>Token-Callout</DisplayName>
    <Properties/>
    <Request clearPayload="true" variable="myRequest">
        <IgnoreUnresolvedVariables>false</IgnoreUnresolvedVariables>
    </Request>
    <Response>calloutResponse</Response>
    <ScriptTarget>
        <ResourceURL/>
    </ScriptTarget>
</ServiceCallout>

Any pointer appreciated.
