JSON Pointer #

A simple library for creating and using json-pointer (See rfc6901).

Examples #

  // Json Pointer Manipulation
  compose(['one', 'two']); // '/one/two'
  split('/one/two'); // ['one', 'two']
  parent('/one/two'); // '/one'
  append('/one', 'two'); // '/one/two'
  isValid('/one/two'); // true

  // Json Pointer Part manipulation
  escape('one/two'); // 'one~1two'
  unescape('one~1two'); // 'one/two'

  // Get and Set values in a json object
  var obj = [
    {'foo': 'bar'}
  ]

  get$('/0/foo', obj); // 'bar'
  set$('/0/foo', obj, 'baz'); // [{'foo': 'baz'}]
  contains('/0/foo', obj); // true

Escaping Examples #

  // Compose escapes parts
  compose(['one/two', 'three']); // '/one~1two/three'

  // Append escapes the added part
  append('/one', 'two/three'); // '/one/two~1three'

  // Split unescapes parts
  split('/one~1two/three'); // ['one/two', 'three']

Traversal #

The library is only able to traverse through objects of type Map and List. Functions will generally throw BadRouteError when attempting to traverse other types. contains will return false.

class Point {
  Point(this.x, this.y);
  int x;
  int y;
}

contains('/x', Point(0, 0)) // false
contains('', Point(0, 0)) // true, this is ok as Point is never traversed
