[ 07 Key Takeaways ](#key-takeaways) What Actually Changed in Laravel 12 ----------------------------------- Laravel 12 is a **minimal-surface release** — the framework team deliberately kept breaking changes small so teams can upgrade without a multi-sprint refactor. That does not mean nothing changed. Several decisions affect how you scaffold new projects and which helpers you reach for day-to-day. --- ### Slimmer Application Skeleton The default `laravel/laravel` skeleton lost several files that previously shipped but were rarely touched: - `app/Http/Kernel.php` is gone — middleware is now registered entirely in `bootstrap/app.php` (this started in L11 but L12 finalises the pattern). - `app/Providers/BroadcastServiceProvider.php` and `app/Providers/EventServiceProvider.php` are no longer generated; their responsibilities live in `AppServiceProvider` or `bootstrap/app.php`. - The `routes/channels.php` and `routes/console.php` files are opt-in rather than always present. If you are upgrading an existing L11 app, **none of your existing files are deleted** — the skeleton change only affects `laravel new` projects. --- ### First-Party Starter Kits Laravel 12 ships three official starter kits via `laravel/breeze` and a new `laravel/react` / `laravel/vue` path: ```bash # React starter (Inertia v2, TypeScript, Tailwind v4) laravel new my-app --using=react # Vue starter laravel new my-app --using=vue # Livewire starter (Volt or class-based) laravel new my-app --using=livewire ``` Each kit now includes **WorkOS AuthKit** as an optional authentication layer, giving you social login and SSO out of the box. You can opt out and keep the classic email/password flow. > **Practical note:** The `--using` flag delegates to the kit's own installer. If your CI pipeline runs `laravel new`, pin the kit version explicitly to avoid unexpected scaffold changes between patch releases. --- ### New and Refined Helpers #### `Number::spell()` and `Number::ordinal()` ```php use Illuminate\Support\Number; Number::spell(42); // "forty-two" Number::ordinal(3); // "3rd" Number::ordinal(21); // "21st" ``` These are thin wrappers around PHP's `NumberFormatter` — no extra dependency, locale-aware via the `locale` argument. #### `Str::chopStart()` / `Str::chopEnd()` ```php Str::chopStart('https://example.com', 'https://'); // "example.com" Str::chopEnd('report.csv', '.csv'); // "report" ``` Clean replacements for the `ltrim`/`rtrim` + manual prefix pattern you have written a hundred times. #### `once()` helper ```php function expensiveComputation(): int { return once(fn () => /* runs exactly once per request lifecycle */ 42); } ``` `once()` memoises the return value of a closure for the duration of the request (or Octane worker tick). It is backed by `Illuminate\Support\Once` and is safe across repeated calls from different call sites. --- ### Upgrade Checklist For teams moving from Laravel 11: 1. **Run `php artisan about`** on L11 first; note any custom providers. 2. Update `composer.json`: `"laravel/framework": "^12.0"`. 3. Check your `bootstrap/app.php` — if you registered middleware in a custom `Kernel`, migrate it to the fluent API: ```php // bootstrap/app.php return Application::configure(basePath: dirname(__DIR__)) ->withMiddleware(function (Middleware $middleware) { $middleware->append(\App\Http\Middleware\TrustProxies::class); }) ->create(); ``` 4. Search for `Illuminate\Http\Middleware\TrustHosts` — it is now enabled by default; remove duplicate registrations. 5. Run `php artisan config:clear && php artisan cache:clear` before deploying. 6. Review the [official upgrade guide](https://laravel.com/docs/12.x/upgrade) for any package-specific notes (Sanctum, Passport, Telescope all have L12-compatible releases). --- ### Should You Upgrade Now? If you are on L11 and your app is stable, upgrading is low-risk. The breaking changes are narrow and well-documented. New projects should start on L12 immediately to benefit from the cleaner skeleton and updated starter kits. --- ### Key Takeaways - The skeleton is leaner — `Kernel.php` is gone, providers are consolidated. - Three official starter kits (`react`, `vue`, `livewire`) with optional WorkOS auth. - `Str::chopStart()`, `Str::chopEnd()`, `Number::spell()`, `Number::ordinal()`, and `once()` are worth adopting immediately. - Upgrading from L11 is straightforward; the main work is migrating any custom `Kernel` middleware to `bootstrap/app.php`. - Pin starter kit versions in CI to avoid scaffold drift.

No. Laravel 12 has a small breaking-change surface. Most teams complete the upgrade in a few hours. The main task is migrating any custom HTTP Kernel middleware registrations to the fluent API in bootstrap/app.php. Q02 What is the `once()` helper and when should I use it? once() memoises a closure's return value for the lifetime of the current request or Octane worker tick. Use it to avoid redundant expensive computations — database lookups, heavy calculations — that are called from multiple places but should only run once per request. Q03 Do the new starter kits replace Laravel Breeze and Jetstream? The new --using flag kits are the spiritual successor to Breeze for React/Vue/Livewire stacks. Jetstream remains a separate package for teams that need its team management features. Breeze itself is updated to delegate to the new kits.
