stream-data-range

Get the minimun and maximum of the attributes of a stream of objects. It will try to parse values as Numbers, but if this results to NaN it will stick with the String.

Install with

npm install stream-data-range

Example

var range = require('stream-data-range')
producer.pipe(range(function (metadata) {
   console.dir(metadata)
}))

Global Usage

You can also install it global with

npm install stream-data-range -g

Assuming a data.ldjson

  {a: 1, b:100}
  {a: 2, b:10}
  {a: 3, b:1}

result will be

$ data-range < data.ldjson
{a: {min: 1, max: 3}, b: {min: 1, max: 100}}
