Definition template

The template looks like normal definition but may include references to variables in the syntax @param1, @param2. Definition templates enable code reuse. They may in turn reference other templates.

const params = ['and', [
  ['address', '$address'], 
  ['in data feed', [['MO7ZZIU5VXHRZGGHVSZWLWL64IEND5K2'], 'timestamp', '>=', '$ts']]
]];

client.post.definitionTemplate(params, wif, function(err, result) {
  console.log(result);
});
