jsonaught

JSON recursive search library (available on npm jsonaught

If you have a large and deep JSON structure and you want to find something in it, this is the library for you.

Installation

$ npm install jsonaught

Example

Say you have an annoying JSON structure.

var data = [
  {tag: 'td'},
  {tag: 'inner', children: [{tag: 'td'}]},
  {tag: 'other', children: [{tag: 'td'}]},
  {
    tag: 'outer',
    children1: [
      {tag: 'inner', children: [{tag: 'td', hit: 'first'}]}
    ],
    other: {tag: 'td'},
    another: {tag: 'inner', other: {tag: 'td', hit: 'second'}}
  }
]

And you want to find all the {tag: 'td'} elements that are somewhere within an element that has {tag: 'inner'} which is itself somewhere inside an element that has {tag: 'outer'}.

You can find these by defining a query and calling the library

// ES6 format
var query = [
  {
    tag: 'outer'
  },
  {
    tag: 'inner'
  },
  {
    tag: 'td'
  }
];

result = (new JSONaught(data)).search(...query);

Or, in good old ES5

// ES5 format
result = (new JSONaught(data)).search({
    tag: 'outer'
  },
  {
    tag: 'inner'
  },
  {
    tag: 'td'
  });

Either of these should return an array of references to the two elements of the data JSON that satisfy the query.
