sha-anything/dist/index.js

A tiny TS utility to sha256 anything, including objects (with sorted keys option). Uses native crypto in browser & NodeJS.

import { sha256 as _sha256 } from 'crypto-hash';
import { sort } from 'fast-sort';
import { isArray, isObject, isSymbol } from 'is-what';
export function sortObject(obj, options) {
    const { deep = false } = options || {};
    let entries = Object.entries(obj);
    if (deep) {
        entries = entries.map((entry) => isObject(entry[1])
            ? [entry[0], sortObject(entry[1], options)]
            : isArray(entry[1])
                ? [entry[0], sortArray(entry[1], options)]
                : entry);
    }
    return Object.fromEntries(sort(entries).asc(([key]) => key));
}
export function sortArray(array, options) {
    const { deep = false } = options || {};
    if (deep) {
        array = array.map((val) => isObject(val) ? sortObject(val, options) : isArray(val) ? sortArray(val, options) : val);
    }
    return sort(array).asc();
}
export async function sha256(payload, options) {
    const { sort = false, deepSort = false } = options || {};
    if (isSymbol(payload))
        throw new Error('Cannot sha256 a symbol');
    if (isObject(payload)) {
        return _sha256(JSON.stringify(sort || deepSort ? sortObject(payload, { deep: deepSort }) : payload));
    }
    if (isArray(payload)) {
        return _sha256(JSON.stringify(sort || deepSort ? sortArray(payload, { deep: deepSort }) : payload));
    }
    return _sha256(`${payload}`);
