What are unique-slug's main functionalities?

Generate a unique slug

This feature generates a unique slug that can be used where a unique string is needed, such as for a unique filename or URL component.

const uniqueSlug = require('unique-slug');
const slug = uniqueSlug();
console.log(slug);

Generate a unique slug with a prefix

This feature allows for the generation of a unique slug with a specified prefix, which can be useful for categorizing or identifying the type of resource the slug represents.

Other packages similar to unique-slug

shortid

Shortid is a package that generates short, non-sequential, URL-friendly unique ids. Unlike unique-slug, which combines a timestamp with a random string, shortid generates shorter identifiers that are easier to read and type. It's often used for URL shorteners or anywhere a shorter identifier is beneficial.

uuid

UUID is a package that generates RFC-compliant UUIDs (Universally Unique Identifiers). It provides different versions of UUIDs, such as v1 (timestamp-based) and v4 (random). While unique-slug generates a unique string based on timestamp and randomness, UUID provides a standardized format for unique identifiers, which can be important for interoperability and when a universally accepted unique identifier format is required.

nanoid

NanoID is a tiny, secure URL-friendly unique string ID generator. It is similar to unique-slug in that it generates unique strings, but it offers a customizable alphabet and size, allowing for a wider range of possible IDs and control over the length of the generated ID. NanoID claims to be a more secure and compact alternative to UUID.
