Your function `opts.cmp` is called with these\nparameters:\n\n``` js\nopts.cmp({ key: akey, value: avalue }, { key: bkey, value: bvalue })\n```\n\nFor example, to sort on the object key names in reverse order you could write:\n\n``` js\nvar stringify = require('fast-json-stable-stringify');\n\nvar obj = { c: 8, b: [{z:6,y:5,x:4},7], a: 3 };\nvar s = stringify(obj, function (a, b) {\n    return a.key < b.key ? 1 : -1;\n});\nconsole.log(s);\n```\n\nwhich results in the output string:\n\n```\n{\"c\":8,\"b\":[{\"z\":6,\"y\":5,\"x\":4},7],\"a\":3}\n```\n\nOr if you wanted to sort on the object values in reverse order, you could write:\n\n```\nvar stringify = require('fast-json-stable-stringify');\n\nvar obj = { d: 6, c: 5, b: [{z:3,y:2,x:1},9], a: 10 };\nvar s = stringify(obj, function (a, b) {\n    return a.value < b.value ? 1 : -1;\n});\nconsole.log(s);\n```\n\nwhich outputs:\n\n```\n{\"d\":6,\"c\":5,\"b\":[{\"z\":3,\"y\":2,\"x\":1},9],\"a\":10}\n```\n\n### cycles\n\nPass `true` in `opts.cycles` to stringify circular property as `__cycle__` - the result will not be a valid JSON string in this case.\n\nTypeError will be thrown in case of circular object without this option.\n\n\n# install\n\nWith [npm](https://npmjs.org) do:\n\n```\nnpm install fast-json-stable-stringify\n```\n\n\n# benchmark\n\nTo run benchmark (requires Node.js 6+):\n```\nnode benchmark\n```\n\nResults:\n```\nfast-json-stable-stringify x 17,189 ops/sec ±1.43% (83 runs sampled)\njson-stable-stringify x 13,634 ops/sec ±1.39% (85 runs sampled)\nfast-stable-stringify x 20,212 ops/sec ±1.20% (84 runs sampled)\nfaster-stable-stringify x 15,549 ops/sec ±1.12% (84 runs sampled)\nThe fastest is fast-stable-stringify\n```\n\n\n# license\n\n[MIT](https://github.com/epoberezkin/fast-json-stable-stringify/blob/master/LICENSE)\n","maintainers":[{"name":"esp","email":"e.poberezkin@me.com"}],"time":{"modified":"2017-10-24T17:44:01.875Z","created":"2017-10-24T09:21:39.783Z","1.0.2":"2017-10-24T09:21:39.783Z","2.0.0":"2017-10-24T17:44:01.875Z"},"homepage":"https://github.com/epoberezkin/fast-json-stable-stringify","keywords":["json","stringify","deterministic","hash","stable"],"repository":{"type":"git","url":"git://github.com/epoberezkin/fast-json-stable-stringify.git"},"author":{"name":"James Halliday","email":"mail@substack.net","url":"http://substack.net"},"bugs":{"url":"https://github.com/epoberezkin/fast-json-stable-stringify/issues"},"license":"MIT","readmeFilename":"README.md","_attachments":{},"_etag":"W/\"1f716e61d86db3c85a4dc06d6aadf1d5\"","_lastModified":"Sun, 27 May 2018 00:24:53 GMT","_cached":true}
