Sorted version of JSON.stringify() so you can get a consistent hash from stringified data. Zero dependencies, ~450 bytes uncompressed.

Versus the leading brand:

💨 30% faster

🗜️ 98% smaller (20.2kb with deps vs 0.45k and no deps)

Usage

Install with your favorite package manager. The API is the same as JSON.stringify, and the library mostly wraps that.

import { stringify } from 'tiny-stable-stringify';

const obj = { z: 1, a: 2 };

console.info(stringify(obj));

// output is: {"a":2,"z":1}

Supports nested objects, sorting all keys consistently.

Handles the upcoming raw JSON feature, but just returns these unchanged with no sorting applied.

Notes

This package doesn't support custom sorting because we (ab)use JS' record type which puts integers first. But you don't care, you just want the keys to be sorted.

Requirements

I'm sure this is very upsetting, but this library requires a JS engine that supports WeakMap, Object.keys, Array.isArray, and JSON.stringify.
