Tracking: ESLint 10 Support

[sergeyklay]

Context

After upgrading to ESLint 10.0.0 in #269, multiple peer dependency warnings indicate incomplete ecosystem support. This issue tracks progress on adding full compatibility with ESLint 10.

Compatibility Status

Package	Status	Upstream Issue
eslint-config-next	✅ Ready	Supports flat config
eslint-plugin-jsx-a11y	⚠️ Partial	Works, peer dep warnings only
eslint-plugin-import	❌ Blocked	#3227
eslint-plugin-react	❌ Blocked	#3977, #3979
eslint-plugin-react-hooks	❌ Blocked	Depends on eslint-plugin-react
typescript-eslint	✅ Ready	#11952

Known Issues

eslint-plugin-import (#3227)

• Error: TypeError: Cannot use 'in' operator to search for 'sourceType' in undefined
• Status: Open issue, no fix available yet
• Impact: Medium - affects import/export linting rules
   

eslint-plugin-react (#3977, #3979)

• Error: TypeError: contextOrFilename.getFilename is not a function
• Status: Open issues, currently using @ledsun fork as workaround
• Impact: High - breaks React component linting
   

typescript-eslint (#11952)

• Status: Enhancement request opened, work in progress
• Impact: High - affects all TypeScript linting

eslint-plugin-jsx-a11y

• Status: Supports flat config but peer dependency range not updated
• Impact: Low - works but shows warnings
   

eslint-plugin-react-hooks

• Status: No specific issue, likely needs update with eslint-plugin-react
• Impact: Medium - affects React Hooks linting

Key Findings

• eslint-plugin-react: Using @ledsun fork as temporary workaround due to getFilename() API breakage (see chore(deps-dev): bump eslint from 9.39.2 to 10.0.0 #269)
• typescript-eslint: Enhancement request open, typically 1-2 months lag for major ESLint versions
• eslint-plugin-import: sourceType accessor errors, no timeline for fix

Action Items

• Monitor eslint-plugin-import#3227 for updates
• Monitor eslint-plugin-react#3977 for official fix
• Monitor typescript-eslint#11952 for release
• Test removing the @ledsun fork once upstream fixes are available
• Update package.json to use official releases when ready
• Remove peer dependency override warnings
