Subrequests JSON Merger

This module allow you to alter the format of the single response you get from Subrequests. Instead of merging the sub-responses into a multipart/related HTTP response, using this module we can merge them into a JSON object.

This JSON object will be keyed by request ID (possible expanded because of JSONPath queries). Each top-level value is an object itself. Such objects contain the headers and the body of the response.

Usage

Inject the merger into subrequests when making a request.

const JsonReponse = require('subrequests-json-merger');

subrequests.request(
  blueprint,
  new HttpRequestor(),
  JsonReponse // Make Subrequests produce a JSON document with all the responses.
)
.then(singleResponse => doYourStuff(singleResponse));

Using the example in the Subrequests module you will get the following output:

{
  "req1": {
    "headers": {
      "content-length": "23",
      "…": "…",
      "x-subrequest-id": "req1",
      "Content-ID": "<req1>"
    },
    "body": "{\n  \"my-key\": \"lorem\"\n}"
  },

    "headers": {
      "x-frame-options": "deny",
