# json-stable-stringify
This is the same as https://github.com/substack/json-stable-stringify but it doesn't depend on libraries without licenses (jsonify).
deterministic version of `JSON.stringify()` so you can get a consistent hash
from stringified results
You can also pass in a custom comparison function.
[](https://ci.testling.com/substack/json-stable-stringify)
[](http://travis-ci.org/substack/json-stable-stringify)
# example
``` js
var stringify = require('json-stable-stringify');
var obj = { c: 8, b: [{z:6,y:5,x:4},7], a: 3 };
console.log(stringify(obj));
```
output:
```
{"a":3,"b":[{"x":4,"y":5,"z":6},7],"c":8}
```
# methods
``` js
var stringify = require('json-stable-stringify')
```
## var str = stringify(obj, opts)
Return a deterministic stringified string `str` from the object `obj`.
## options
### cmp
If `opts` is given, you can supply an `opts.cmp` to have a custom comparison
function for object keys. Your function `opts.cmp` is called with these
parameters:
``` js
opts.cmp({ key: akey, value: avalue }, { key: bkey, value: bvalue })
```
For example, to sort on the object key names in reverse order you could write:
``` js
var stringify = require('json-stable-stringify');
var obj = { c: 8, b: [{z:6,y:5,x:4},7], a: 3 };
var s = stringify(obj, function (a, b) {
return a.key < b.key ? 1 : -1;
});
console.log(s);
```
