Created ESLint configuration and auto-fixed code style violations to resolve CI/CD pipeline linting failures. ## Problem CI/CD pipeline was failing at the linting step: ``` ESLint couldn't find a configuration file. ``` The project had ESLint installed but no configuration, causing the lint step in the pipeline to fail. ## Solution ### 1. Created .eslintrc.json **Configuration Details:** - Environment: Browser, ES2021, Node - Extends: eslint:recommended - Parser: ES Modules, latest ECMAScript - Rules: - 4-space indentation - Unix line endings - Single quotes (with escape allowance) - Semicolons required - Unused vars as warnings (prefixed with _ ignored) - Console allowed (common in development) ### 2. Auto-Fixed Code Issues Ran `eslint --fix` to automatically resolve: - ✅ 16 indentation errors (standardized to 4 spaces) - ✅ Formatting inconsistencies - ✅ Code style violations **Remaining:** - 6 warnings for unused parameters (acceptable, won't fail CI) - These are interface parameters maintained for consistency ## Files Modified - .eslintrc.json (new) - ESLint configuration - js/engine/MoveValidator.js - indentation fixes - js/engine/SpecialMoves.js - indentation fixes - js/main.js - style fixes - js/pieces/King.js - formatting - js/pieces/Piece.js - formatting ## Verification ```bash npm run lint ✖ 6 problems (0 errors, 6 warnings) ``` ✅ No errors - pipeline will pass ⚠️ 6 warnings - informational only, don't fail build ## Impact ✅ CI/CD linting step will now succeed ✅ Consistent code style across project ✅ Automated style checking on all commits ✅ Better code readability and maintainability 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
