Click **Remix** to get your own copy.\n\n## Picking a starter\n\n| Starter | When to pick it |\n| --- | --- |\n| [`basic-html-starter`](https://www.val.town/x/templates/basic-html-starter) | Static HTML pages. Sprinkle of vanilla JS. No server-side rendering. |\n| [`hono-jsx-starter`](https://www.val.town/x/templates/hono-jsx-starter) | Dynamic server-rendered HTML with JSX. API routes. No React, no SPA. |\n| **[`react-hono-starter`](https://www.val.town/x/templates/react-hono-starter)** *(you're here)* | Client-side React SPA with a Hono API backend. |\n\n**Want to build UI?** Start writing React components in\n[`frontend/components/`](/frontend/components/). Import them into `App.tsx` and\nyou're good to go. Styling is [Twind](https://twind.style/) — just use Tailwind\nutility classes, zero config.\n\n**Want to add an API?** Add routes in [`index.ts`](/index.ts) (there's a\ncommented-out example). Fetch them from your React components.\n\n## Architecture\n\n```mermaid\ngraph LR\n Browser -->|\"GET /\"| Hono[\"index.ts
(Hono server)\"]\n Hono -->|serves| HTML[\"index.html\"]\n HTML -->|loads| Entry[\"index.tsx\"]\n Entry -->|renders| App[\"App.tsx\"]\n App -->|renders| Counter[\"Counter.tsx\"]\n```\n\n## File structure\n\n```\nindex.ts ← Hono backend (serves frontend + API routes)\nfrontend/\n index.html ← HTML shell (loads Twind + React)\n index.tsx ← React entrypoint (mounts )\n favicon.svg ← App icon\n components/\n App.tsx ← Root component (layout + view source link)\n Counter.tsx ← Example component with state\n```\n\n## How it works\n\n1. **`index.ts`** is the HTTP entrypoint — a Hono server that serves the\n frontend and any API routes you add.\n2. **`frontend/index.html`** loads Twind and the React entrypoint.\n3. **`frontend/index.tsx`** mounts the React app.\n4. **`frontend/components/App.tsx`** is the root layout — add new components\n alongside it.\n5. **`frontend/components/Counter.tsx`** is an example stateful component —\n replace it with your own!\n\n## Next steps\n\n- Add API routes in `index.ts`\n- Add new components in `frontend/components/`\n- Add a SQLite database — see the\n [React Hono Example](https://www.val.town/x/stevekrouse/reactHonoExample) for\n a full-stack example with database, queries, and shared types\n",[166],"998c928e-5b29-11f1-ade4-ee650bb23af1","shared","4bf500f0-a2c3-4407-bdf4-f9a1d3d934bd",3,["D",1780036965295],"directory",[172],"8c33d3b8-5b29-11f1-b770-ee650bb23af1","frontend","019e7278-3c24-74da-90c1-5e428350c16e",["D",1780036942807],[179],"9460f5de-5b29-11f1-ade4-ee650bb23af1","backend","e5ac08fe-1c39-4951-8ff9-301c59fa9a2a",2,["D",1780036956621],[184],"pulls","branches","forks","envVars",{"_196":69,"_198":69},"connections",{"_196":69,"_197":69},"count","unfilledCount","emptyCount",{"_48":183,"_37":184,"_35":185,"_157":-5,"_46":47,"_45":186,"_159":65,"_43":294,"_13":69,"_39":176,"_41":-5,"_29":30,"_163":-5,"_215":295,"_32":296},{"_48":287,"_37":288,"_35":289,"_157":185,"_46":47,"_45":186,"_159":65,"_43":290,"_13":69,"_39":40,"_41":291,"_29":30,"_163":-5,"_215":292,"_32":293},{"_48":279,"_37":280,"_35":281,"_157":185,"_46":47,"_45":282,"_159":65,"_43":283,"_13":69,"_39":40,"_41":284,"_29":30,"_163":-5,"_215":285,"_32":286},{"_48":275,"_37":38,"_35":36,"_157":185,"_46":47,"_45":14,"_159":65,"_43":276,"_13":69,"_39":40,"_41":42,"_29":30,"_163":-5,"_215":277,"_32":278},{"_48":178,"_37":179,"_35":180,"_157":-5,"_46":47,"_45":158,"_159":65,"_43":272,"_13":69,"_39":176,"_41":-5,"_29":30,"_163":-5,"_215":273,"_32":274},{"_48":268,"_37":260,"_35":255,"_157":180,"_46":47,"_45":158,"_159":65,"_43":269,"_13":69,"_39":176,"_41":-5,"_29":30,"_163":-5,"_215":270,"_32":271},{"_48":261,"_37":262,"_35":263,"_157":255,"_46":47,"_45":158,"_159":65,"_43":264,"_13":69,"_39":40,"_41":265,"_29":30,"_163":-5,"_215":266,"_32":267},{"_48":252,"_37":253,"_35":254,"_157":255,"_46":47,"_45":158,"_159":65,"_43":256,"_13":69,"_39":40,"_41":257,"_29":30,"_163":-5,"_215":258,"_32":259},{"_48":245,"_37":246,"_35":247,"_157":180,"_46":47,"_45":158,"_159":65,"_43":248,"_13":69,"_39":26,"_41":249,"_29":30,"_163":-5,"_215":250,"_32":251},{"_48":238,"_37":239,"_35":240,"_157":180,"_46":47,"_45":158,"_159":65,"_43":241,"_13":69,"_39":26,"_41":242,"_29":30,"_163":-5,"_215":243,"_32":244},{"_48":231,"_37":232,"_35":233,"_157":180,"_46":47,"_45":158,"_159":65,"_43":234,"_13":69,"_39":40,"_41":235,"_29":30,"_163":-5,"_215":236,"_32":237},{"_48":171,"_37":172,"_35":173,"_157":-5,"_46":47,"_45":174,"_159":65,"_43":228,"_13":69,"_39":176,"_41":-5,"_29":30,"_163":-5,"_215":229,"_32":230},{"_48":221,"_37":222,"_35":223,"_157":173,"_46":47,"_45":174,"_159":65,"_43":224,"_13":69,"_39":40,"_41":225,"_29":30,"_163":-5,"_215":226,"_32":227},{"_48":165,"_37":166,"_35":167,"_157":-5,"_46":47,"_45":158,"_159":65,"_43":218,"_13":69,"_39":26,"_41":169,"_29":30,"_163":-5,"_215":219,"_32":220},{"_48":155,"_37":156,"_35":63,"_157":-5,"_46":47,"_45":158,"_159":30,"_43":214,"_13":69,"_39":161,"_41":162,"_29":30,"_163":-5,"_215":216,"_32":217},["D",1780036942807],"children",[],[156],["D",1780036942807],[],[166],"998c7e34-5b29-11f1-ade4-ee650bb23af1","types.ts","998c7efc-5b29-11f1-ade4-ee650bb23af1",["D",1780036965295],"/** Types shared between the Hono backend and the React frontend. */\n\nexport interface Candle {\n time: number;
