|

|
|
*
|
||
|
|
* | Order | Event | Context | Middleware |

||
|
|
* |-------|-------|---------|------------|

|
|
* Note: Events marked "1" are mutually exclusive based on context.

|
* ## Request/Collect Pattern
|
||
|
|
*
|
||
|
|
* This class implements a "request/collect" pattern rather than direct mutation:
|
||
|
|
*
|
||
|
|
* 1. **Modules request** resources via methods like `routes()`, `views()`, etc.
|
||
|
|
* 2. **Requests are collected** in arrays during event dispatch
|
||
|
|
* 3. **LifecycleEventProvider processes** collected requests with validation
|
||
|
|
*
|
||
|
|
* This pattern ensures modules cannot directly mutate infrastructure and allows
|
||
|
|
* the framework to validate, sort, and process requests centrally.
|
||
|
|
*
|
||
|
|
* ## Available Request Methods
|
||
|
|
*
|
||
|
|
* | Method | Purpose |
|
||
|
|
* |--------|---------|
|
||
|
|
* | `routes()` | Register route files/callbacks |
|
||
|
|
* | `views()` | Register view namespaces |
|
||
|
|
* | `livewire()` | Register Livewire components |
|
||
|
|
* | `middleware()` | Register middleware aliases |
|
||
|
|
* | `command()` | Register Artisan commands |
|
||
|
|
* | `translations()` | Register translation namespaces |
|
||
|
|
* | `bladeComponentPath()` | Register anonymous Blade component paths |
|
||
|
|
* | `policy()` | Register model policies |
|
||
|
|
* | `navigation()` | Register navigation items |
|
||
|
|
*
|
||
|
|
* ## Event Versioning
|
||
|
|
*
|
||
|
|
* Events support versioning for backwards compatibility. The version number
|
||
|
|
* indicates the API contract version:
|
||
|
|
*
|
||
|
|
* - Version 1: Original API (current)
|
||
|
|
* - Future versions may add methods but maintain backwards compatibility
|
||
|
|
*
|
||
|
|
* Check version with `$event->version()` in your handlers to support multiple
|
||
|
|
* event versions during transitions.
|
||
|
|
*
|
||
|
|
* ## Usage Example
|
||
|
|
*
|
||
|
|
* ```php
