Hi everyone! Thanks for checking out prefID. I built prefID because I kept needing clean, prefixed IDs like user_xxx, order_xxx, and invoice_xxx across different projects. While libraries like UUID and NanoID are excellent, I found myself repeatedly writing custom logic to add prefixes, keep IDs consistent, and support different ID formats. So I built prefID which is likee a lightweight, zero-dependency library for generating prefixed IDs with multiple generation strategies. Key features: Zero dependencies Cryptographically secure random IDs Sortable IDs for time-ordered data Distributed-system friendly ID generation Built-in prefixes (user_, order_, invoice_, etc.) URL-safe output Custom prefixes, separators, length, and alphabets Full TypeScript support Works in Node.js, Bun, Deno, and modern browsers Example: import { id, sid } from "prefid"; id("user"); // user_F7kP3Qn2... sid("order"); // order_01K4... Whether you're building APIs, databases, event-driven systems, or distributed applications, prefID aims to make ID generation simple, consistent, and flexible. I'd genuinely love your feedback on the API, documentation, performance, or feature ideas. If there's something you'd like to see added, let me know! Thanks for taking the time to check it out, and I hope prefID makes your next project a little easier.
