The line you bet is stored on the ticket,\n so your pricing never moves after you place the bet.\n- A full bet history shows every ticket with its result.\n\n## Setup (one step)\n\nThe app needs a free **The Odds API** key (free tier: 500 requests/month, enough\nfor personal use — each page refresh uses a couple of credits):\n\n👉 Add ODDS_API_KEY here: https://www.val.town/x/michaelfreedman/nfl-betting-app/environment-variables?key=ODDS_API_KEY\n\n1. Grab a free key at (choose the Free plan).\n2. Add it as the `ODDS_API_KEY` environment variable using the link above.\n3. Reload the app — the slate and odds will appear.\n\n> Note: The Odds API reports the **NFL season's current slate** (regular season\n> onward). During the offseason there are no games with odds, and the app shows\n> an empty state.\n\n## Architecture\n\n```mermaid\ngraph LR\n Browser -->|\"GET /\"| Hono[\"index.ts (Hono server)\"]\n Browser -->|\"/api/*\"| Hono\n Hono -->|fetch lines + scores| OA[\"The Odds API\"]\n Hono -->|read/write| DB[\"SQLite (bankroll + bets)\"]\n Hono -->|serves| UI[\"frontend/ (React + Twind)\"]\n UI -->|place bet / refresh| Hono\n```\n\n- `index.ts` — Hono backend: serves the SPA and the JSON API (`/api/games`,\n `/api/bets`, `/api/history`, `/api/reset`).\n- `lib/data.ts` — The Odds API client: fetches `odds` (lines) and `scores`\n (final results), merges them, maps team names to logos, and settles games.\n- `lib/db.ts` — SQLite layer: bankroll, bet placement, and bet settlement.\n- `frontend/lib/api.ts` + `frontend/components/` — the React UI.\n\n## Data + settlement details\n\n- `spread` is stored as the **home** team's line (negative = home favored).\n Spread picks settle against the final margin; a tie is a push (stake refunded).\n- `overUnder` bets push if the total lands exactly on the line.\n- On each load, finished games are settled against the **lines stored on your\n tickets** and the bankroll is credited/lossed atomically.\n- Team logos and abbreviations are resolved locally; odds and scores come live\n from The Odds API.\n\n[View source](url:index.ts/source)\n",[],[208],"32dab4e2-d7ca-4ee1-8925-605bff1ffb20","CHANGELOG.md","01a083dd-a784-740f-ad04-2ea34a70660d",["D",1788918736700],"# 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. Create `frontend/root.tsx`:\n\n```tsx\n/** @jsxImportSource npm:hono@4/jsx */\nimport { raw } from \"npm:hono@4/html\";\nimport { immutableFileUrl } from \"https://esm.town/v/std/utils/index.ts\";\n\n// The HTML shell for the app. It is never cached, so immutableFileUrl can stamp\n// the current val version into each asset URL — the browser caches those\n// immutably, and publishing the val changes the URLs, refetching exactly once.\nexport function Root() {\n return (\n <>\n {raw(\"<!DOCTYPE html>\")}\n <html lang=\"en\">\n <head>\n <meta charSet=\"UTF-8\" />\n <meta name=\"viewport\" content=\"width=device-width, initial-scale=1.0\" />\n <title>React Hono Val Town Starter\n
