node-red-contrib-data-tracer v0.1.0

NodeRed Data Tracer

It helps enriching given object with metadata.
It add information about when the data has been treated and by which NodeRed flow.

E.g. the following object...

{
    id: 123,
    name: 'qwerty',
    // ...
}

...will be enriched as following:

{
    id: 123,
    name: 'qwerty',
    // ...
    _metadata: {
        logs: [
            {
                flowName: 'example-collector',
                time: 1545218628149,
            },
            {
                flowName: 'example-enricher',
                time: 1545218628151,
            },
        ],
    },
}
