laravel-opcualisted

# laravel-opcua A thin, idiomatic Laravel layer over `php-opcua/opcua-client`. Three things to remember: 1. The Facade `PhpOpcua\LaravelOpcua\Facades\Opcua` proxies the full `OpcUaClientInterface`. Anything `opcua-client` can do, the Facade can do. 2. `OpcuaManager::shouldUseSessionManager()` decides per-call whether to instantiate a direct `Client` (TCP straight to the server) or a `ManagedClient` (IPC to the long-lived daemon). The decision is transparent to application code. 3. v4.4.0 picked up 21 new client methods (HistoryUpdate, File transfer, Aggregates). They are reachable through `Opcua::*` and `Opcua::connection('plc-1')->*` without any config or service-provider change. ## What this package is for | You want to | Use | |---|---| | Read / write OPC UA nodes from a controller, job, command | `Opcua::read()`, `Opcua::write()` (Facade) | | Talk to multiple OPC UA servers | Named connections in `config/opcua.php`, `Opcua::connection('plc-1')` | | Connect to a runtime-discovered endpoint | `Opcua::connectTo($url, $configOverrides, as: 'cache-key')` | | Avoid one new TCP connection per HTTP request | Run `php artisan opcua:session` as a supervised daemon | | React to data changes, alarms, etc. via PSR-14 → Laravel Event system | Configure `auto_publish: true` + `auto_connect: true` + `subscriptions: [...]` | | Test code that touches OPC UA without a server | `PhpOpcua\Client\MockClient` + Facade swap, see `references/TESTING.md` | | Stream notifications to Livewire /
