From 56e107a650ea84c39b44615d612dabd4f4c5f0d4 Mon Sep 17 00:00:00 2001 From: msmart Date: Fri, 27 Jun 2025 17:33:22 +1000 Subject: [PATCH 1/3] feat: add exponential backoff and connection status tracking MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implement WebSocket connection resilience and monitoring features: ## Exponential Backoff - Replace fixed reconnection delays with exponential backoff (2s โ†’ 4s โ†’ 8s โ†’ 16s โ†’ 30s cap) - Prevent server overwhelming during outages - Maintain default 5 reconnection attempts ## Connection Status Tracking - Add ConnectionStateManager for real-time connection monitoring - Track connection status: connecting, connected, disconnected, error - Collect connection statistics: uptime, reconnect attempts, total connections - Emit status change events for reactive UI updates ## Client API Enhancements - Add connection actions to PublicShredClient and PublicSyncClient - New methods: getConnectionStatus(), getConnectionStats(), isConnected() - Subscribe to connection changes with onConnectionChange() - Async waitForConnection() with configurable timeout ## Developer Experience - Full backward compatibility - existing code works unchanged - TypeScript support with proper type definitions - Comprehensive test coverage (28 new tests) - Live examples for reconnection and connection monitoring - Updated README with usage documentation All changes are non-breaking with sensible defaults. ๐Ÿค– Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- README.md | 77 +++++ examples/connection-monitoring.ts | 124 ++++++++ examples/reconnection-test.ts | 100 +++++++ src/viem/clients/createPublicShredClient.ts | 7 +- src/viem/clients/createPublicSyncClient.ts | 7 +- src/viem/clients/decorators/connection.ts | 128 ++++++++ src/viem/types/connection.ts | 16 + src/viem/utils/connection/manager.ts | 52 ++++ src/viem/utils/rpc/socket.ts | 32 +- .../backward-compatibility.test.ts | 61 ++++ .../clients/decorators/connection.test.ts | 116 ++++++++ .../decorators/connectionActions.test.ts | 277 ++++++++++++++++++ .../rpc/socket.exponential-backoff.test.ts | 78 +++++ 13 files changed, 1067 insertions(+), 8 deletions(-) create mode 100644 examples/connection-monitoring.ts create mode 100644 examples/reconnection-test.ts create mode 100644 src/viem/clients/decorators/connection.ts create mode 100644 src/viem/types/connection.ts create mode 100644 src/viem/utils/connection/manager.ts create mode 100644 tests/integration/backward-compatibility.test.ts create mode 100644 tests/viem/clients/decorators/connection.test.ts create mode 100644 tests/viem/clients/decorators/connectionActions.test.ts create mode 100644 tests/viem/utils/rpc/socket.exponential-backoff.test.ts diff --git a/README.md b/README.md index 0e70c5d..fa48522 100644 --- a/README.md +++ b/README.md @@ -38,6 +38,9 @@ With this method, you can send a transaction and receive extremely fast response -

3bb82e86198618a2c9f30c344c4ac04f22a8f361 Mon Sep 17 00:00:00 2001 From: msmart Date: Fri, 27 Jun 2025 23:58:17 +1000 Subject: [PATCH 2/3] feat: add request queue and dynamic subscription management MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements comprehensive WebSocket request management with: - Request queue with priority handling and retry logic - Dynamic subscription management for efficient event streaming - Connection-aware processing with automatic pause/resume - Extensive test coverage and example implementations Key features: - Priority-based request queuing (high/normal/low) - Configurable retry policies with exponential backoff - Dynamic subscription updates without reconnection - Request batching and processing statistics - Memory-efficient event buffering This enhancement improves reliability and performance for WebSocket-based operations, particularly beneficial for high-throughput scenarios. ๐Ÿค– Generated with
