ObjectID64

Encodes and decodes UUID, MongoDB’s ObjectId, numbers, and bigints to and from base64. The character set is configurable, by default the library uses the following url-friendly character set: ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789-_.

Features:

Shortens id strings:
- UUID from 36 characters to 22
- ObjectId from 24 to 16
- numbers as strings up to 4 times fewer characters
As fast as JavaScript gets.
Configurable character set.

Usage

In Node.js

npm i objectid64

import { ObjectId64 } from "objectid64";

In Deno:

import { ObjectId64 } from "https://raw.githubusercontent.com/zandaqo/objectid64/3.0.0/mod.ts";

const encoder = new ObjectId64();

const objectId = new ObjectId().toHexString();
//=> '581653766c5dbc10f0aceb55'
let encoded = encoder.fromObjectId(objectId);
//=> 'WBZTdmxdvBDwrOtV'
let decoded = encoder.toObjectId(encoded);
//=> '581653766c5dbc10f0aceb55'

const uuid = crypto.randomUUID();
//=> "6d2bb408-3176-42d3-b473-3d251f19569f"
encoded = encoder.fromUUID(uuid);
//=> "bSu0CDF2QtO0cz0lHxlWCf"
decoded = encoder.toUUID(encoded);
//=> "6d2bb408-3176-42d3-b473-3d251f19569f"

With a custom character set:

const encoder = new ObjectId64(
  "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789-_",
);

const objectId = new ObjectId().toHexString();
//=> '581653766c5dbc10f0aceb55'
let encoded = encoder.fromObjectId(objectId);
//=> 'wbztDMXDVbdWRoTv'
let decoded = encoder.toObjectId(encoded);
//=> '581653766c5dbc10f0aceb55'

const uuid = crypto.randomUUID();
//=> "6d2bb408-3176-42d3-b473-3d251f19569f"
encoded = encoder.fromUUID(uuid);
//=> "bSu0CDF2QtO0cz0lHxlWCf"
decoded = encoder.toUUID(encoded);
//=> "6d2bb408-3176-42d3-b473-3d251f19569f"
