Enhanced Template Literals - Converted string concatenations to template literals across all lib/ files - Improved readability of error messages and HTTP response building - Updated complex multi-line concatenations in WebSocketClient.js and WebSocketRequest.js - Replaced debug/logging string concatenations in WebSocketFrame.js ## 2. Arrow Functions - Converted appropriate function expressions to arrow functions - Updated forEach callbacks, event handlers, and utility functions - Improved code conciseness while maintaining proper `this` binding - Updated functions in WebSocketServer.js, WebSocketClient.js, WebSocketRequest.js, and utils.js ## 3. Destructuring - Simplified object property extraction patterns - Added destructuring for constructor property assignments - Implemented array destructuring for frame header parsing - Reduced repetitive property access in WebSocketRouterRequest.js and other files ## Testing - All existing tests pass (30/30) - No linting errors - Maintains backward compatibility with Node.js 4.x+ - No breaking changes to public APIs ๐Ÿค– Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- lib/W3CWebSocket.js | 6 ++-- lib/WebSocketClient.js | 23 ++++++------- lib/WebSocketConnection.js | 27 +++++++-------- lib/WebSocketFrame.js | 14 ++++---- lib/WebSocketRequest.js | 62 ++++++++++++++++------------------- lib/WebSocketRouter.js | 2 +- lib/WebSocketRouterRequest.js | 27 ++++++++++----- lib/WebSocketServer.js | 14 ++++---- lib/browser.js | 4 +-- lib/utils.js | 16 ++++----- 10 files changed, 96 insertions(+), 99 deletions(-) diff --git a/lib/W3CWebSocket.js b/lib/W3CWebSocket.js index 3a23f359..1b4542b4 100644 --- a/lib/W3CWebSocket.js +++ b/lib/W3CWebSocket.js @@ -192,10 +192,12 @@ function createMessageEvent(data) { function onConnect(connection) { const self = this;

charset=UTF-8 Content-Transfer-Encoding: 8bit The test was waiting for both 'request' and 'connectFailed' events simultaneously, but the connectFailed event only occurs after we attempt to accept with the wrong protocol. Fixed by: 1. Wait for the request event first 2. Verify the requested protocol 3. Set up connectFailed listener 4. Attempt accept with wrong protocol (which throws and triggers connectFailed) 5. Wait for and verify the connectFailed event All tests now pass consistently. ๐Ÿค– Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- test/unit/core/request.test.mjs | 20
