Summary of Changes
Hello @theturtle32, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request represents the successful completion of the first phase in modernizing the codebase, specifically targeting the test suite. By adopting contemporary ES6 features, the tests are now more readable and maintainable, laying a solid foundation for subsequent refactoring efforts on the core library while ensuring no regressions were introduced and compatibility is preserved.
Highlights
- Test Suite Modernization: The primary goal of this PR is to complete Phase 1 of the ES6 refactoring plan by updating the entire test suite to use modern JavaScript patterns.
- ES6 Pattern Adoption: Key ES6 features like
const/letfor variable declarations, template literals for string interpolation, and arrow functions for concise callbacks have been applied across the test files. - Code Quality & Compatibility: Ensures all tests pass (26/26), linting is clean (JSHint), and backward compatibility with Node.js 4.x+ is maintained.
- Minor Core Library Fixes: Includes small fixes in core library files, such as removing an unused import, correcting a potential const mutation in cookie parsing, and adding a JSHint global directive.

Code Review
This pull request does a great job modernizing the test suite to ES6 patterns, including the use of const/let, template literals, and some arrow functions. The codebase is definitely cleaner and more modern as a result. The fix for the const mutation in lib/WebSocketRequest.js and the removal of the unused util import in lib/WebSocketConnection.js are also good improvements.
The main area for improvement is the consistent application of arrow functions for anonymous callbacks. While many have been converted, several instances remain in files like test/scripts/echo-server.js, test/scripts/memoryleak-client.js, and test/scripts/memoryleak-server.js. Addressing this would fully align the changes with the stated goal of modernizing anonymous callbacks.
Overall, this is a solid step forward in the refactoring plan.

Based on Gemini Code Assist review feedback, convert remaining anonymous function expressions to arrow functions for consistency across the test suite: - test/scripts/echo-server.js: Convert event handlers and callbacks - test/scripts/memoryleak-client.js: Convert connection event handlers - test/scripts/memoryleak-server.js: Convert server and connection callbacks - test/unit/: Convert all test callback functions and event handlers - test/shared/: Convert remaining server and process event handlers Maintains existing functionality while achieving consistent modern syntax. All 26 tests pass ✅ Linting passes ✅ 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>

Code Review
This pull request successfully modernizes the test suite to ES6 patterns and transitions the linting from JSHint to ESLint. The changes are extensive and well-summarized. The introduction of an ESLint configuration is a positive step for code consistency.
My review focuses on:
- The new ESLint configuration in
.eslintrc.js, particularly rules that have been turned off, as some of these could introduce risks or reduce code clarity. - Opportunities for further ES6 modernization (e.g.,
vartoconst/let, arrow functions) within the modified lines of thelib/files, aligning with the PR's goals. - Ensuring consistency with the newly established ESLint rules (e.g., indentation).
The changes to documentation and package.json align well with the overall goals of the PR.
- Remove gulp and gulp-eslint dependencies - Add lint and lint:fix npm scripts using ESLint directly - Update GitHub Actions workflow to run npm run lint - Update CLAUDE.md documentation with new commands - Remove gulpfile.js as it's no longer needed 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
