fastPath

An attempt at an optimized jsonpath parser

Check the spec here: http://goessner.net/articles/JsonPath/

Use

var fastpath = require('fastpath');

var matcher = fastpath(pattern);

// or

var matcher = fastpath({
    name: pattern,
    name2: pattern2
});

matcher.evaluate(object);

Pattern	Description
$	the root object/element
@	the current object/element
. or []	child operator
..	recursive descent
*	wildcard - All objects/elements regardless of their names
[]	Native array operator
[,]	Names or array indices
[start : end : step]	Slices subset of the array based on the start, end and step values
?()	applies a filter

The tape tests have most of the patterns supported by the spec.
