Templating

Add "transformers": ["response-template"] to a response and its body/headers become a Handlebars template. Templates can read the request and call helpers.

"response": {
  "status": 200,
  "transformers": ["response-template"],
  "jsonBody": {
    "echo": "{{jsonPath request.body '$.name'}}",
    "when": "{{now format='yyyy-MM-dd HH:mm:ss'}}",
    "id":   "{{randomValue type='UUID'}}"
  }
}

The request model

{{request.method}}, {{request.url}}, {{request.body}}, {{request.path.[0]}} (or a named {{request.path.id}}), {{request.query.page}}, {{request.headers.[Content-Type]}}, {{request.cookies.session}}.
