🚀 Boost your Laravel apps with globally unique identifiers—covering UUID v4, ULID, and Ordered UUID (UUID v7). Learn when and how to implement each for enhanced security, performance, and scalability.
- UUIDs (v4) — Random, globally unique IDs perfect for preventing ID enumeration and improving security.
- ULIDs — Compact, lexicographically sortable, URL-friendly identifiers.
- Ordered UUIDs (UUID v7) — Time-ordered, high-performance IDs that improve database indexing and write speed.
Dive into how to set them up using Laravel 12 migrations, Eloquent traits (HasUuids & HasUlids), and simple controller methods.
- Security & privacy: Random or non-sequential IDs help prevent attackers from guessing resource counts.
- Global uniqueness: Ideal for distributed systems where merging or syncing across databases matters.
- Performance-friendly: Ordered UUIDs significantly reduce index fragmentation and optimize large table inserts.
| Step | Description |
|---|---|
| 1⃣ | Create UUID-based migration: <code>$table->uuid('id')->primary();</code> |
| 2⃣ | Use HasUuids or HasUlids trait in your model to auto-generate IDs. |
| 3⃣ | Customize UUID generation via newUniqueId() for specific behaviors like UUID v4. |
| 4⃣ | Choose your ID format depending on your use case: |
- Use `Str::uuid()` for random UUIDs
- Use `Str::orderedUuid()` (UUID v7) for better indexing
- Use ULIDs with `HasUlids` trait for short, URL-safe IDs
