hexoid

What is hexoid?

The hexoid npm package is a small, fast library for generating unique hex string IDs. It is designed to be efficient and provides a simple API for generating random or sequential hex strings that can be used for unique identifiers in various applications.

What are hexoid's main functionalities?

Generate random hex string IDs

This feature allows you to generate random hex string IDs. The code sample shows how to import the hexoid package, create a generator function, and then log a new unique hex string ID to the console.

"use strict"; const hexoid = require('hexoid'); const generateId = hexoid(); console.log(generateId());

Generate custom length hex string IDs

This feature allows you to specify the length of the hex string ID. In the code sample, a 16-character hex string ID is generated.

"use strict"; const hexoid = require('hexoid'); const generateId = hexoid(16); console.log(generateId());

Other packages similar to hexoid

uuid

The uuid package is a popular library for generating unique identifiers. Unlike hexoid, which generates hex strings, uuid can generate UUIDs (Universally Unique Identifiers) according to various versions (v1, v3, v4, v5). UUIDs are typically longer and follow a specific format, which includes hyphens and can be more recognizable as a standard ID format.

shortid

Shortid is another package that generates short, non-sequential, URL-friendly unique IDs. The main difference between shortid and hexoid is that shortid generates alphanumeric IDs that are shorter and more suited for URLs, whereas hexoid focuses on hex strings which are not necessarily URL-friendly but can be more compact.

nanoid

Nanoid is a tiny, secure, URL-friendly, unique string ID generator for JavaScript. It is similar to hexoid in terms of providing a simple API for generating unique IDs, but it offers a customizable alphabet and size, which allows for a wider range of possible IDs beyond just hexadecimal characters.
