+# fast-json-stable-stringify
+
+Deterministic `JSON.stringify()` - a faster version of [@substack](https://github.com/substack)'s json-stable-strigify without [jsonify](https://github.com/substack/jsonify).
+
+You can also pass in a custom comparison function.
+
+[![Build Status](https://travis-ci.org/epoberezkin/fast-json-stable-stringify.svg?branch=master)](https://travis-ci.org/epoberezkin/fast-json-stable-stringify)
+[![Coverage Status](https://coveralls.io/repos/github/epoberezkin/fast-json-stable-stringify/badge.svg?branch=master)](https://coveralls.io/github/epoberezkin/fast-json-stable-stringify?branch=master)
+
+# example
+
+``` js
+var stringify = require('fast-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('fast-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('fast-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);
+```
+
+which results in the output string:
+
+```
+{"c":8,"b":[{"z":6,"y":5,"x":4},7],"a":3}
+```
+
+Or if you wanted to sort on the object values in reverse order, you could write:
+
+```
+var stringify = require('fast-json-stable-stringify');
+
+var obj = { d: 6, c: 5, b: [{z:3,y:2,x:1},9], a: 10 };
+var s = stringify(obj, function (a, b) {
+    return a.value < b.value ? 1 : -1;
+});
+console.log(s);
+```
+
+which outputs:
+
+```
+{"d":6,"c":5,"b":[{"z":3,"y":2,"x":1},9],"a":10}
+```
+
+### cycles
+
+Pass `true` in `opts.cycles` to stringify circular property as `__cycle__` - the result will not be a valid JSON string in this case.
+
+TypeError will be thrown in case of circular object without this option.
+
+
+# install
+
+With [npm](https://npmjs.org) do:
+
+```
+npm install fast-json-stable-stringify
+```
+
+
+# benchmark
+
+To run benchmark (requires Node.js 6+):
+```
+node benchmark
+```
+
+Results:
+```
+fast-json-stable-stringify x 17,189 ops/sec ±1.43% (83 runs sampled)
+json-stable-stringify x 13,634 ops/sec ±1.39% (85 runs sampled)
+fast-stable-stringify x 20,212 ops/sec ±1.20% (84 runs sampled)
+faster-stable-stringify x 15,549 ops/sec ±1.12% (84 runs sampled)
+The fastest is fast-stable-stringify
+```
