jsonaught

JSON recursive search library

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

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.
