Remote Log Writers

Client-side log writers that send log data to remote endpoints. Source: Loggers/ in this project. For core logging framework see AyCode.Core/docs/LOGGING.md. For server-side GlobalLogger see AyCode.Core.Server/docs/LOGGING_SERVER.md.

AcBrowserConsoleLogWriter

Blazor browser console writer. Extends AcTextLogWriterBase (text branch, not structured). Uses IJSRuntime to invoke browser console methods:

LogLevel	JS method
Detail – Suggest	`console.info`
Warning	`console.warn`
Error	`console.error`

Implements IAcLogWriterClientBase (client-side marker).

AcHttpClientLogItemWriter<TLogItem>

HTTP POST writer. Extends AcLogItemWriterBase<TLogItem> (structured branch). Manages its own HttpClient + HttpClientHandler. Sends log items as JSON:

_httpClient.PostAsJsonAsync(_url, logItem).Forget();

Note: Forget() — fire-and-forget, no await on the HTTP response. HTTP/2 by default.

AcSignaRClientLogItemWriter

SignalR log transport writer. Extends AcLogItemWriterBase<AcLogItemClient>. Sends items to a dedicated logger hub. Manages its own HubConnection:

_hubConnection.SendAsync("AddLogItem", logItem).Forget();

UTC conversion note: SignalR doesn't transmit DateTime.Kind. The writer calls logItem.TimeStampUtc.ToUniversalTime() before sending to ensure the server receives actual UTC.

Connection lifecycle: StartConnection() waits up to 10s for Connected state. StopConnection() stops and disposes the hub.

Remote Logging Flow

Client applications can send log items to a server via SignalR:

Client App                           Server
──────────                           ──────
AcSignaRClientLogItemWriter          AcLoggerSignalRHub<TLogger>
  │                                    │
  │  logItem.ToUniversalTime()         │
  │  StartConnection()                 │
  ├──SendAsync("AddLogItem", item)──►  │
  │                                    ├─ logItem.TimeStampUtc = UtcNow
  │                                    ├─ _logger.Write(logItem)
  │                                    │    ├─ Console writer
  │                                    │    ├─ DB writer
  │                                    │    └─ ... (all server writers)

Note: AcLoggerSignalRHub overrides the client's TimeStampUtc with DateTime.UtcNow on the server side for authoritative timestamps. The hub is a simple Hub (not AcWebSignalRHubBase) — it does NOT use tag-based dispatch.
