# SignalR Endpoints and External Integrations
> Part of `Nop.Plugin.Misc.FruitBankPlugin`. See `README.md` for project overview.
> For measurement workflows see `docs/MEASUREMENT.md`.
> For data layer see `docs/DATA_LAYER.md`.
The plugin communicates with FruitBankHybridApp (MAUI client) via SignalR. Methods decorated with `[SignalR]` attributes auto-broadcast results to connected clients.
## SignalR Configuration
Configured in `PluginNopStartup`:
| Setting | Value |
|---|---|
| KeepAliveInterval | 30 seconds |
| ClientTimeoutInterval | 30 seconds |
| MaximumReceiveMessageSize | 30 MB |
| EnableDetailedErrors | true |
| StatefulReconnectBufferSize | 30 MB |
| **HubProtocol** | **`AcBinaryHubProtocol`** (singleton `IHubProtocol`) |
**Wire protocol:** `AcBinaryHubProtocol` (`AyCode.Services.SignalRs`, from `AyCode.Services.dll`) — custom binary `IHubProtocol` using `AcBinarySerializer`. Eliminates JSON+Base64 overhead. Requires `TransferFormat.Binary` → WebSocket transport only. Protocol name: `"acbinary"`. Registered as `services.AddSingleton<IHubProtocol>(new AcBinaryHubProtocol())` after `AddSignalR()`.
Hubs registered: `DevAdminSignalRHub`, `LoggerSignalRHub` (from AyCode.Core.Server).
## FruitBankHub
`Services/FruitBankHub.cs` — Minimal hub inheriting `Hub`.
| Method | Purpose |
|---|---|
| `SendMessage(string user, string message)` | Broadcast message to all connected clients |
## CustomOrderSignalREndpoint
`Areas/Admin/Controllers/CustomOrderSignalREndpoint.cs` — Order management via SignalR. Implements `ICustomOrderSignalREndpointServer`.
### Query Methods
| Method | Parameters | Returns | Broadcast Tag |
|---|---|---|---|
| `GetAllOrderDtos()` | — | Orders from last 15 days with relations | — |
| `GetOrderDtoById` | orderId | Single order with relations | — |
| `GetPendingOrderDtos()` | — | Pending status orders | — |
| `GetPendingOrderDtosForMeasuring` | lastDaysCount | Orders for measurement (unpaid, not cancelled, with DateOfReceipt) | — |
| `GetAllOrderDtoByIds` | orderIds[] | Batch retrieval | — |
| `GetAllOrderDtoByProductId` | productId | Orders containing product | — |
### Mutation Methods
| Method | Parameters | Broadcast Tag | Key Logic |
|---|---|---|---|
| `StartMeasuring` | orderId, userId | `SendOrderChanged` | Sets MeasurementOwnerId, OrderStatus=Processing, PaymentStatus=Pending |
| `SetOrderStatusToComplete` | orderId, revisorId | `SendOrderChanged` | Validates pallets, recalculates prices, updates stock, publishes OrderPaidEvent |
| `AddOrUpdateMeasuredOrderItemPallet` | OrderItemPallet | `SendOrderItemPalletChanged` | Saves pallet, triggers price recalculation |
### Order Item & Pallet Queries
| Method | Purpose |
|---|---|
| `GetOrderItemDtosByOrderId` | Items for a specific order |
| `GetOrderItemPalletsByOrderItemId` | Pallets for a specific item |
| `GetOrderItemPalletById` | Single pallet |
## StockSignalREndpointServer
`Areas/Admin/Controllers/StockSignalREndpointServer.cs` — Inventory management via SignalR.
| Method | Parameters | Key Logic |
|---|---|---|
| `GetStockTakings` | loadRelations | All stock taking sessions |
| `AddStockTaking` | StockTaking | Creates session, auto-populates items from products + pending order items |
| `CloseStockTaking` | stockTakingId | Validates all measured, applies stock corrections, marks closed |
| `UpdateStockTaking` | StockTaking | Updates session |
| `RefreshStockTakingItem` | stockTakingItemId | Refreshes measured values from pallets |
| `GetStockTakingItems` | loadRelations | All items |
| `GetStockTakingItemsByStockTakingId` | stockTakingId | Filtered items |
| `AddOrUpdateMeasuredStockTakingItemPallet` | StockTakingItemPallet | Saves pallet, refreshes item values |
## FruitBankDataController
