The Ultimate Ultra-Fast, Zero-Dependency ID & Token Generator for Enterprise Systems

Solving the JavaScript ID Fragmentation Problem

Developers building high-performance applications often juggle multiple ID generation packages: uuid for databases, nanoid for URL-friendly strings, cuid2 or ulid for distributed systems, and custom solutions for API keys or prefixed IDs. This fragmentation complicates dependency management, increases supply-chain attack surfaces, and creates inconsistent tooling across projects.

The @readytools/id package consolidates these needs into a single solution. It provides UUIDv1, v4, v5, and v7, ULID, CUID2, NanoID with custom alphabet support, Snowflake IDs, Stripe-style prefixed IDs, secure tokens, and human-readable IDs-all without adding dependencies.

Performance and Security Advantages

Built exclusively with the native Web Crypto API, @readytools/id avoids Math.random and ensures cryptographically secure randomness. It uses highly optimized bitwise operations, achieving performance benchmarks of up to 9 million operations per second for native crypto bindings. The package is fully tree-shakable, meaning bundlers like Webpack, Vite, Rollup, or esbuild only include the specific generators used in your code.

For database applications, UUIDv7 and ULID provide chronologically sortable identifiers that reduce B-Tree index fragmentation in PostgreSQL and MySQL. The package includes utilities for converting UUIDs to compact 16-byte Uint8Array formats for efficient storage and retrieval.

Enterprise Tooling and Developer Experience

Deterministic testing features allow developers to seed the generator for reproducible snapshot tests. The collision risk calculator uses the Birthday Paradox to mathematically determine collision probabilities based on alphabet length, ID length, and expected count.

Validation and inspection utilities include checks for ID validity, version detection, and timestamp extraction. The package works across Node.js 18+, React, Next.js, Deno, Bun, Cloudflare Workers, Vercel Edge, and modern browsers.

CLI tools enable direct terminal usage for ID generation and risk calculation. TypeScript typings and predictable naming conventions make the package compatible with AI coding assistants like Copilot, ChatGPT, and Claude.

Installation requires a single command: npm install @readytools/id .
