- Downgrade ESLint from v10.1.0 to v8.57.1
- Create .eslintrc.json config (ESLint v8 format)
- Remove eslint.config.js (flat config format)
- ESLint LSP (vscode-langservers-extracted) doesn't support ESLint v10+
The vscode-eslint-language-server from vscode-langservers-extracted v4.10.0
is not compatible with ESLint v10's Flat Config format. Downgrading to
ESLint v8 ensures the ESLint LSP in Neovim works correctly.
- Created eslint.config.js using the new flat config format
- Removed .eslintrc.json (old format no longer supported in ESLint v9+)
- Maintained same configuration as before (next/core-web-vitals, next/typescript)
- Kept same ignore patterns
- Fixed unused variables in unit tests (elo.test.ts, permissions.test.ts)
- Fixed unused variables in E2E tests (account-acceptance.test.ts, elo-ratings.test.ts, epic1-auth-registration.test.ts, global.setup.ts)
- Fixed 'any' type usage in EditTournamentForm.test.tsx and auth-simple.test.ts
- Fixed unescaped quotes and apostrophes in React components
- Fixed TypeScript type errors in Navigation.tsx, test-api/page.tsx, and matches/upload/page.tsx
- Fixed missing useEffect dependency in tournaments/[id]/entry/page.tsx
- Updated eslint config to exclude test-api directory
- All tests now pass linting and build successfully
