Package Exports

fast-safe-stringify

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (fast-safe-stringify) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

fast-safe-stringify

Safely and quickly serialize JavaScript objects

Detects circular dependencies instead of throwing (as per usual JSON.stringify usage)

Usage

var safeStringify = require('fast-safe-stringify')
var o = {a: 1}
o.o = o

console.log(safeStringify(o))
console.log(JSON.stringify(o)) //<-- throws

Benchmarks

The json-stringify-safe module supplies similar functionality with slightly more info. Although not JSON, the core util.inspect method can be used for similar purposes (e.g. logging) and also handles circular references.

Here we compare fast-safe-stringify with these alternatives:

inspectBench*10000: 163.506ms
jsonStringifySafeBench*10000: 71.508ms
fastSafeStringifyBench*10000: 35.447ms
inspectBench*10000: 135.528ms
jsonStringifySafeBench*10000: 64.065ms
fastSafeStringifyBench*10000: 33.956ms

fast-safe-stringify is 2x faster than json-stringify-safe and 4x faster than util.inspect.
