Val Town runs Deno (TypeScript), not\nPython, so this uses **Hono** — a lightweight web framework with the same\nroute/middleware feel as FastAPI — instead of FastAPI itself.\n\n[Open the shop](url:index.ts)\n\n## Stack\n\n- **Backend**: Hono REST API (`api/routes.ts`), cookie-based session cart\n- **Database**: Val Town SQLite (`db/schema.ts`) — products, cart, orders, order_items\n- **Frontend**: Client-side React SPA (`frontend/`), Twind for styling\n\n## Architecture\n\n```mermaid\ngraph LR\n Browser -->|GET /| Hono[\"index.ts (Hono)\"]\n Hono -->|serves| Root[\"frontend/root.tsx\"]\n Root -->|loads| App[\"frontend/components/App.tsx\"]\n App --> ProductList\n App --> CartPanel\n App --> Checkout\n Browser -.->|fetch /api/*| API[\"api/routes.ts\"]\n API --> DB[(SQLite)]\n```\n\n## API routes\n\n| Method | Path | Description |\n| --- | --- | --- |\n| GET | `/api/products` | List all products |\n| GET | `/api/products/:id` | Get one product |\n| GET | `/api/cart` | Get current session's cart |\n| POST | `/api/cart` | Add item to cart `{ productId, quantity }` |\n| PATCH | `/api/cart/:productId` | Update quantity `{ quantity }` (0 removes) |\n| DELETE | `/api/cart/:productId` | Remove item from cart |\n| POST | `/api/checkout` | Place order `{ name, email }`, clears cart |\n| GET | `/api/orders/:id` | Get an order + its line items |\n\n## File structure\n\n```\nindex.ts ← Hono entrypoint (serves frontend + /api)\napi/routes.ts ← All REST API routes\ndb/schema.ts ← SQLite schema + seed data\nfrontend/\n root.tsx ← HTML shell\n index.tsx ← React entrypoint\n lib/api.ts ← Typed fetch client for the API\n components/\n App.tsx ← Root layout / view router\n ProductList.tsx ← Product grid\n CartPanel.tsx ← Cart sidebar\n Checkout.tsx ← Checkout form\n OrderConfirmation.tsx ← Post-order confirmation\n```\n\n## Next steps\n\n- Add product images/categories\n- Add an admin view to manage inventory\n- Add auth so orders are tied to real user accounts instead of a cart cookie\n",[],[199],"8fa491da-7567-43d0-8e01-e9d19fff6f8f","CHANGELOG.md","01a08fd2-faaf-742b-b80a-825098e8b7ab",["D",1789119363697],"# Changelog\n\n## 2026-07-30 — Immutable asset caching\n\nFrontend files are now served at version-addressed URLs\n(`/__immutable/45/frontend/index.tsx`) with\n`Cache-Control: public, max-age=31536000, immutable`, so repeat visits load the\nwhole client graph from the browser cache — roughly 3× faster (~665ms → ~157ms\nmeasured). Publishing your val bumps its version, which changes every URL, so\ncaches invalidate automatically. Old-version URLs return 404 after a publish\n(like Next.js build assets); a reload picks up the new version.\n\nWhat changed in the template:\n\n- `frontend/index.html` → [`frontend/root.tsx`](/frontend/root.tsx): the HTML\n shell is now JSX and stamps asset URLs with `immutableFileUrl()`\n- [`index.ts`](/index.ts): serves `Root()` at `/`, and one\n `app.get(\"/__immutable/*\", (c) => serveImmutableFile(c.req.path))` route\n serves all frontend files\n\n### Upgrading an existing remix\n\nYour copy of this template doesn't update automatically. Two options:\n\n**Minimal (most of the benefit):** point both routes at `serveImmutableFile` —\nyour existing bare URLs redirect into versioned space, the new route serves\nthem, and the whole module graph gets cached (costs one redirect per page view):\n\n```ts\nimport { serveImmutableFile } from \"https://esm.town/v/std/utils/index.ts\";\n\napp.get(\"/__immutable/*\", (c) => serveImmutableFile(c.req.path));\napp.get(\"/frontend/**/*\", (c) => serveImmutableFile(c.req.path)); // was serveFile\n```\n\n**Full upgrade (also removes the redirect):** three self-contained steps —\nno other files needed. Adjust the ``, favicon, and body of `Root()` to\nmatch your app's existing `index.html`, and stamp anything else your shell\nreferences directly (images, css) with `immutableFileUrl()`.\n\n1.
