rolling-pin v0.1.0

Rolling Pin

Flatten out nasty nested JSON into something simpler and smoother.

Try it out at: http://rolling-pin.ahungry.com/

Interactively (GUI or code lib) turn this:

{
  "person": {
    "identifyingInformation": {
      "hint": "Click 'name' and enter name in the prompt, then 'uuid' and enter 'id'.",
      "fullName": "Matthew Carter",
      "uuid": "abc-123"
    },
    "physicalCharacteristics": {
      "head": {
        "eyes": {
          "left": {
            "hint": "Click 'color' and enter 'leftEye' in the prompt.",
            "color": "blue"
          },
          "right": {
            "hint": "Click 'color' and enter 'rightEye' in the prompt.",
            "color": "blue"
          }
        }
      }
    }
  }
}

into this:

{
  "name": "Matthew Carter",
  "id": "abc-123",
  "leftEye": "blue",
  "rightEye": "blue"
}

With two-way data-mapping.

Libs

Add to your project with:

npm install rolling-pin || yarn add rolling-pin

Simple example

const { transform } = require('rolling-pin')

console.log(transform([['a.b', 'x.y']])({a: { b: 3 }}))

// { x: { y: 3 } }

More complex example

const { transform } = require('rolling-pin')

const mapping = [
  ['headers.Host'  , 'host'],
  ['origin'        , 'origin'],
  ['json.sentinel' , 'sentinel'],
]
const t = transform(mapping)

const x = t({
  headers: { Host: 'some-host' },
  origin: 'some-origin',
  json: { sentinel: 'some-sentinel' },
})

// Which will produce x as follows:
{
  host: 'some-host',
  origin: 'some-origin',
  sentinel: 'some-sentinel'
}
