UUID in Node.js: crypto.randomUUID() vs uuid Package Benchmarked Node.js 14.17 added to the built-in module, and it became globally available in Node.js 19. The npm package remains relevant for v7 sortable UUIDs, v5 deterministic UUIDs, and environments with older Node.js versions. Here is a complete comparison with real benchmarks. --- crypto.randomUUID() — Built-in Since Node 14.17 No npm install. No dependency. The implementation calls (libuv's cryptographically secure RNG) on all platforms. How it compares to the uuid package For quick generation without writing code, try the UUID Generator tool. --- uuid Package — v4, v5, v7, Validation UUID v4 (random) UUID v5 (deterministic) UUID v7 (sortable timestamps) Validation --- Performance Benchmarks Benchmarked on Node.js 22, Apple M3, 1…
