i18n Routing

Chinese is the bare path (/, /algo, /about); English is prefixed with /en. The URL is the single source of truth for language — use-lang.ts derives it from the path, and LangSync in __root.tsx keeps i18next and document.lang in sync.

UI strings live in src/locales/{zh,en}.json; long-form content lives as per-locale MDX under src/content/{zh_tw,en}/.

Development

Requires Node.js 22+ and pnpm.

pnpm install  # install dependencies
pnpm dev      # start dev server at localhost:3000
pnpm build    # production build
pnpm check    # format + lint + type-check

Contributing

Contributions are welcome! Feel free to open an issue or submit a pull request.

• Bug reports — please include steps to reproduce and the expected behavior.
• New features — open an issue first to discuss before sending a PR.
• i18n — UI strings are in src/locales/{zh,en}.json; keep both files in key parity.
• Code style — run pnpm check before submitting; the project uses Biome for linting and formatting.
