Anso 82a4e94589 chore(stack-files): client-side path-traversal guard in stackFilesApi (#1190)
The backend already rejects path-traversal attempts through
isValidRelativeStackPath, so the server side is safe today. Adding a
client-side mirror is defense-in-depth: it shortens the failure loop
(no wasted round trip) and protects against a future server-side
regression that loosens validation.

Adds isClientSafeRelPath in frontend/src/lib/stackFilesApi.ts mirroring
the backend predicate (rejects absolute paths, drive letters,
backslashes, NUL bytes, double slashes, and any segment that is `.`
or `..`). Wraps every export that accepts a relPath / targetDir /
fromRel / toRel argument with assertSafeRelPath, throwing a clear
Error before the fetch is issued.

12 unit tests cover the predicate (POSIX accepts, traversal rejects,
Windows drive letters, backslashes, NUL bytes, non-string inputs).
Frontend suite stays at 288/288.

React + TypeScript + Vite

This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.

Currently, two official plugins are available:

React Compiler

The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see this documentation.

Expanding the ESLint configuration

If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:

export default defineConfig([
  globalIgnores(['dist']),
  {
    files: ['**/*.{ts,tsx}'],
    extends: [
      // Other configs...

      // Remove tseslint.configs.recommended and replace with this
      tseslint.configs.recommendedTypeChecked,
      // Alternatively, use this for stricter rules
      tseslint.configs.strictTypeChecked,
      // Optionally, add this for stylistic rules
      tseslint.configs.stylisticTypeChecked,

      // Other configs...
    ],
    languageOptions: {
      parserOptions: {
        project: ['./tsconfig.node.json', './tsconfig.app.json'],
        tsconfigRootDir: import.meta.dirname,
      },
      // other options...
    },
  },
])

You can also install eslint-plugin-react-x and eslint-plugin-react-dom for React-specific lint rules:

// eslint.config.js
import reactX from 'eslint-plugin-react-x'
import reactDom from 'eslint-plugin-react-dom'

export default defineConfig([
  globalIgnores(['dist']),
  {
    files: ['**/*.{ts,tsx}'],
    extends: [
      // Other configs...
      // Enable lint rules for React
      reactX.configs['recommended-typescript'],
      // Enable lint rules for React DOM
      reactDom.configs.recommended,
    ],
    languageOptions: {
      parserOptions: {
        project: ['./tsconfig.node.json', './tsconfig.app.json'],
        tsconfigRootDir: import.meta.dirname,
      },
      // other options...
    },
  },
])
