About

The Fastest UUID v1 Parser and Generator for NodeJS.

The results were obtained by running each function inconsistently 1,000,000 times with NodeJS v20.8.1, R7 6800H, 16g DDR5

Prerequisites

• node >=14.21.3

Install

npm i uuid-wasm

Usage

import { InitUUID } from 'uuid-wasm';

const run = async () => {
    const { v1, nanos, timeFromV1, unsafeTimeFromV1 } = await InitUUID();

    const uuid = v1();
    console.log(uuid);
    // 6335ff92-6a7a-11ee-929a-eedc63b9d38e

    const nanoseconds = nanos();
    console.log(nanoseconds);
    // 1697278437810573000n

    const date1 = timeFromV1(uuid);
    console.log(date1);
    // 2023-10-14T10:13:57.810Z
    console.log(date1.getTime());
    // 1697278547627

    const date2 = unsafeTimeFromV1(uuid);
    console.log(date2);
    // 2023-10-14T10:13:57.810Z
    console.log(date2.getTime());
    // 1697278547627
};

run().catch(console.error);
