Package Exports

deterministic-json

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 (deterministic-json) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

deterministic-json

Deterministic JSON parse/stringify, with support for Buffers

When writing crypto code that needs deterministic JSON strings, usually you're working with a lot of binary data (signatures, ciphertext, public keys, etc.). So for convenience, this module both makes the output deterministic, and lets Buffers survive the stringification/parsing by converting to base64 strings.

Usage

npm install deterministic-json

let json = require('deterministic-json')

let string = json.stringify({ b: 0, c: 1, a: 2, key: Buffer.from('foo') })
// -> '{"a":2,"b":0,"c":1,"key":":base64:Zm9v"}'

let obj = json.parse(string)
// -> { a: 2, b: 0, c: 1, key: <Buffer 66 6f 6f> }
