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",[170],"f94df35a-5e96-11f1-a008-1607ee4eb77e","frontend","019e88ee-890a-72f8-a279-1cf939beedf1",["D",1780413794401],"directory",[176],"31cdaeaa-5e97-11f1-91e4-1607ee4eb77e","backend","d776a2ad-ff3e-4481-8dd0-5ebd71580eb6",2,["D",1780413889356],[182],"pulls","branches","forks","envVars",{"_194":63,"_196":158},"connections",{"_194":158,"_195":158},"count","unfilledCount","emptyCount",{"_42":181,"_31":182,"_29":183,"_154":-5,"_40":41,"_39":184,"_156":59,"_37":293,"_13":158,"_33":179,"_35":-5,"_23":24,"_160":-5,"_213":294,"_26":295},{"_42":285,"_31":286,"_29":287,"_154":183,"_40":41,"_39":288,"_156":24,"_37":289,"_13":158,"_33":34,"_35":290,"_23":24,"_160":-5,"_213":291,"_26":292},{"_42":278,"_31":279,"_29":280,"_154":183,"_40":41,"_39":184,"_156":24,"_37":281,"_13":158,"_33":34,"_35":282,"_23":24,"_160":-5,"_213":283,"_26":284},{"_42":175,"_31":176,"_29":177,"_154":-5,"_40":41,"_39":63,"_156":59,"_37":275,"_13":158,"_33":179,"_35":-5,"_23":24,"_160":-5,"_213":276,"_26":277},{"_42":271,"_31":252,"_29":246,"_154":177,"_40":41,"_39":63,"_156":59,"_37":272,"_13":158,"_33":179,"_35":-5,"_23":24,"_160":-5,"_213":273,"_26":274},{"_42":264,"_31":265,"_29":266,"_154":246,"_40":41,"_39":63,"_156":24,"_37":267,"_13":158,"_33":34,"_35":268,"_23":24,"_160":-5,"_213":269,"_26":270},{"_42":260,"_31":32,"_29":30,"_154":246,"_40":41,"_39":14,"_156":24,"_37":261,"_13":158,"_33":34,"_35":36,"_23":24,"_160":-5,"_213":262,"_26":263},{"_42":253,"_31":254,"_29":255,"_154":246,"_40":41,"_39":63,"_156":24,"_37":256,"_13":158,"_33":34,"_35":257,"_23":24,"_160":-5,"_213":258,"_26":259},{"_42":243,"_31":244,"_29":245,"_154":246,"_40":41,"_39":247,"_156":24,"_37":248,"_13":158,"_33":34,"_35":249,"_23":24,"_160":-5,"_213":250,"_26":251},{"_42":236,"_31":237,"_29":238,"_154":177,"_40":41,"_39":63,"_156":24,"_37":239,"_13":158,"_33":20,"_35":240,"_23":24,"_160":-5,"_213":241,"_26":242},{"_42":229,"_31":230,"_29":231,"_154":177,"_40":41,"_39":63,"_156":24,"_37":232,"_13":158,"_33":20,"_35":233,"_23":24,"_160":-5,"_213":234,"_26":235},{"_42":222,"_31":223,"_29":224,"_154":177,"_40":41,"_39":63,"_156":59,"_37":225,"_13":158,"_33":34,"_35":226,"_23":24,"_160":-5,"_213":227,"_26":228},{"_42":169,"_31":170,"_29":171,"_154":-5,"_40":41,"_39":63,"_156":24,"_37":219,"_13":158,"_33":20,"_35":173,"_23":24,"_160":-5,"_213":220,"_26":221},{"_42":162,"_31":163,"_29":57,"_154":-5,"_40":41,"_39":164,"_156":24,"_37":216,"_13":63,"_33":166,"_35":167,"_23":24,"_160":44,"_213":217,"_26":218},{"_42":151,"_31":152,"_29":153,"_154":-5,"_40":41,"_39":155,"_156":24,"_37":212,"_13":158,"_33":34,"_35":159,"_23":24,"_160":-5,"_213":214,"_26":215},["D",1780414051352],"children",[],[152],["D",1780414192131],[],[163],["D",1780413794401],[],[170],"f94deee6-5e96-11f1-a008-1607ee4eb77e","index.tsx","019e88ee-890a-72f8-a279-1a31fa3e7e92",["D",1780413794401],"/** @jsxImportSource https://esm.sh/react@18.2.0 */\nimport { createRoot } from \"https://esm.sh/react-dom@18.2.0/client\";\nimport { App } from \"./components/App.tsx\";\n\nconst root = document.getElementById(\"root\");\nif (!root) {\n throw new Error(\"No root element found\");\n}\n\ncreateRoot(root).render();",[],[176,223],"f94de7fc-5e96-11f1-a008-1607ee4eb77e","index.html","019e88ee-890a-72f8-a279-15dc455934ab",["D",1780413794401],"\n\n \n \n \n React Hono Val Town Starter\n \n \n \n \n
