- 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.
- Install @types/bun and @types/jsdom for proper type definitions
- Fix mock function typing in test files
- Create jest-dom.d.ts to properly extend Bun's Matchers interface
- Remove MockedFunction imports (not supported in Bun's types)
- Cast global.fetch and useSession mocks to any where needed
- Fix mock.module return types to match expected signatures
This resolves TypeScript errors that were preventing proper code
completion and type checking in IDEs.
ESLint v10.x requires the new flat config format (eslint.config.js),
but the project uses the old .eslintrc.json format. Downgrading to
ESLint v8.x which supports the legacy configuration format.
- Install Bun via mise
- Update package.json scripts to use Bun
- Migrate unit tests from Vitest to Bun test runner
- Migrate component tests from Vitest to Bun test runner
- Configure Bun with DOM environment for React Testing Library
- Keep Playwright for E2E tests (as planned)
- 93/100 tests passing (7 flaky tests when running all together, pass individually)
