You're making a mobile app and need unique codes for things like messages or photos that sort themselves by when they were created.

2
🔍 Discover the speedy ID maker

You find a super-fast tool that creates these time-sorted unique codes perfectly for phone apps.

3
⚡ Add it with ease

You simply include the tool in your app, and it works right away on both iPhone and Android without hassle.

4
✨ Create your first code

Just ask the tool for a new code anytime, and it instantly gives you one that's unique and ready to use, even based on a specific moment in time.

5
🔍 Verify and explore

Check if a code is perfect or uncover the exact time it was born, helping you manage everything smoothly.

🎉 App flies with fast IDs

Now your app handles tons of these codes lightning-quick, keeping items perfectly ordered and users happy.

What is react-native-ulid-jsi?

This React Native library generates ULIDs—sortable, timestamped unique IDs—using C++ and JSI for ultra-fast native performance on iOS and Android. It tackles JS-based ID generation's slowness, delivering 500x speedups with monotonic ordering so IDs stay strictly increasing even in the same millisecond. Users call simple functions like ulid() for generation, isValid() for checks, and decodeTime() to extract timestamps, with full TypeScript types and zero dependencies.

Why is it gaining traction?

Zero serialization overhead via JSI means blazing generation rates (0.17ms per 1000 IDs), platform-secure randomness, and no JS bundle bloat—beats npm ulid libs hands-down for mobile scale. Monotonic mode ensures database-friendly sorting without extra timestamps, much like the ultra-fast lane detection or makeup shaders projects on GitHub prioritize raw speed. New and old React Native architectures just work, hooking devs chasing native-level throughput.

Who should use this?

React Native devs building event streams, logging systems, or offline-first apps needing sortable IDs for local storage or sync. Backend-mobile hybrids generating resource keys or file names in high-volume CRUD flows. Teams on Fabric/TurboModules wanting JSI perks without custom native modules.

Verdict

Grab it for perf-sensitive ULID generation in React Native—docs and benchmarks are pro-level—but with 10 stars and 1.0% credibility, it's immature; prototype heavily and monitor issues before prime time. Solid foundation for ultra-fast native ID needs.
