- How do I install snortlin/nano-id in a Laravel project?
- Run `composer require snortlin/nano-id` in your project directory. The package integrates seamlessly with Laravel’s service container and requires no additional configuration for basic usage. For advanced setups, register the service provider in `config/app.php` if needed.
- Can I use NanoIDs as primary keys in Laravel Eloquent models?
- Yes, but you’ll need to configure your model to use a custom primary key. Set `$primaryKey = 'nano_id'` and `$keyType = 'string'` in your model, then generate IDs via `NanoId::generate()`. Ensure your database column is a `CHAR` or `VARCHAR` type with a UNIQUE constraint to handle collisions.
- What’s the collision risk with snortlin/nano-id, and how do I mitigate it?
- Collision risk is extremely low with default settings (e.g., 21-character IDs have a ~1 in 2^132 chance of collision). For high-volume systems, use longer IDs or implement retry logic in your application. Database UNIQUE constraints will automatically handle duplicates if they occur.
- Does snortlin/nano-id work with Laravel 8, 9, or 10?
- The package is compatible with Laravel 8+ and follows modern PHP standards. It has no strict version dependencies beyond PHP 8.0+, so it should work out of the box with Laravel’s latest releases. Check the package’s `composer.json` for exact PHP version requirements.
- How do I customize the NanoID alphabet or length?
- Use the `generate()` method with parameters: `NanoId::generate(10, 'abcdefghijklmnopqrstuvwxyz0123456789')` for a 10-character ID with a custom alphabet. The default alphabet is URL-safe and includes uppercase letters, lowercase letters, and numbers. Avoid special characters unless explicitly needed.
- Can I use NanoIDs for API tokens or URL slugs in Laravel?
- Absolutely. NanoIDs are ideal for tokens and slugs due to their URL-friendly format and brevity. Replace `Str::random(32)` with `NanoId::generate(10)` for shorter, human-readable tokens or slugs. Ensure your routes or API endpoints handle the string format correctly.
- What’s the performance impact of generating NanoIDs in a loop?
- NanoID generation is highly performant (O(1) complexity) and adds minimal overhead. However, generating thousands of IDs in a tight loop may introduce slight latency. For bulk operations, consider batching or pre-generating IDs outside critical paths.
- How do I test NanoID uniqueness in my Laravel application?
- Write unit tests to verify ID generation by checking for collisions in a controlled environment. Use PHPUnit to generate thousands of IDs and assert uniqueness. For database integration, test UNIQUE constraint handling by simulating duplicate inserts and verifying error responses.
- Are there alternatives to snortlin/nano-id for Laravel?
- Yes, alternatives include `ramsey/uuid` for UUIDs (longer but globally unique) or `spatie/laravel-activitylog` for event-based IDs. For NanoID-style IDs, `web-token/jwt-framework` or custom implementations using `random_bytes()` are options, but `snortlin/nano-id` offers the best balance of simplicity and Laravel integration.
- How do I migrate from auto-increment IDs to NanoIDs in an existing Laravel app?
- Start by adding a new `nano_id` column to your database table, then backfill existing records with generated NanoIDs. Update your model to use the new primary key and ensure all queries, relationships, and ORM features (e.g., `find()`) work with the string-based ID. Test thoroughly in staging before full deployment.
