logd_network 0.1.1

Network-based sinks and real-time observability handlers (HTTP batching, WebSocket streaming, live browser dashboard) for logd.

Changelog

0.1.1

• Web & WASM Compatibility:
  • Replaced dart:io HttpException with http.ClientException in HttpSink to enable full Web and WASM runtime compatibility across browser targets.
• Example & Developer Experience:
  • Hide deprecated core network exports in example/example.dart to prevent shadow analyzer warnings.
  • Added standalone example/example.dart entrypoint.
• Package Metadata:
  • Added explicit target platform declarations (android, ios, linux, macos, web, windows) and topic tags (logging, network, http, websocket, observability).

0.1.0

• Initial release of logd_network, a dedicated satellite package providing HTTP telemetry, WebSocket streaming, and embedded browser dashboards for logd.

  • In-memory log entry batching (batchSize, flushInterval).

• Interactive Showcases & Test Harness:
  • Interactive CLI showcase gallery in example/main.dart with 4 dedicated showcases (http_sink_showcase.dart, socket_sink_showcase.dart, http_server_sink_showcase.dart, http_dashboard_showcase.dart).
  • Comprehensive unit and integration test suite (17/17 tests passing).
