Encoding a payload

Here is a code example of encoding a payload:

var sparkplug = require('@jcoreio/sparkplug-payload/spBv1.0'),
  payload = {
    timestamp: new Date().getTime(),
    metrics: [
      {
        name: 'intMetric',
        value: 1,
        type: 'Int32',
      },
    ],
  },
  encoded = sparkplug.encodePayload(payload)

Decoding a payload

Here is a code example of decoding an encoded payload:

var decoded = sparkplug.decodePayload(encoded)
