json_prune v1.0.0
JSON.prune
JSON.prune is a pruning JSON.stringify for the very specific cases where you need to stringify big or recursive javascript objects and don't really need the result to be complete.
JSON.prune also lets you, in case of need, stringify inherited and/or non enumerable properties.
JSON.prune(window.location, {inheritedProperties:true}); // without inherited properties, FireFox and IE only show an empty object
It's totally useless for at least 99% of js developpers.
JSON.prune.log is a proxy over console.log deep cloning the objects (using JSON.prune) before logging them, in order to avoid the delay problem encountered on non primitive objects logging.
You should not use it frequently, only when you really need to see the objects how they were at logging time.
// make sure someObject is logged as it was at logging time
JSON.prune.log(someObject);
NodeJs usage
Install with npm
npm install json_prune
Use it in node as standard module
var JSONPrune = require('json_prune').prune
...
var prunedObj = JSONPrune(objectToPrune)
Window (browser) usage
Include it
<script src=http://dystroy.org/JSON.prune/.js></script>
Use it with
var json = JSON.stringify(window); // fails
var json = JSON.prune(window); // builds a JSON valid string from a pruned version of the
// recursive, deep, and not totally accessible window object
var prunedWindow = JSON.parse(JSON.prune(window)); // builds a lighter acyclic version of window
