jsref v1.2.0

jsref

Fast, flexible and Tiny (>1kb min) json reference resolver with support for json pointers, external refernences, custom resolvers and path or key based filters.

Usage

On NodeJS

$ npm install jsref --save

var jsref = require('jsref')

var inp = { k1: 'v1', k2: { $ref: '#k1' } }
var res = jsref(inp, { lazy:true } )

In Browser

<script src="https://cdn.rawgit.com/mattaylor/jsref/master/jsref.min.js"></script>
<script>
  var inp = { k1: 'v1', k2: { $ref: '#k1' } }
  var res = jsref(inp, { lazy:true } )
</script>

NOTE: local references must be prefixed by #. Old style JSON schema references eg { $ref: 'string' } will be resolved as remote url paths
