Koncerty, kino, teatr, festyny, sport, wydarzenia dla dzieci.\n\n👉 https://co-w-zamosciu.val.run\n\n## Jak to działa\n\n- **`cron/scrape.ts`** zbiera wydarzenia 3 razy dziennie (6:00, 12:00, 18:00 czasu letniego) z:\n - Biletyna (Zamość, Biłgoraj, Tomaszów Lub., Hrubieszów, Krasnystaw, Chełm): dane schema.org, seanse kin łączone w jedną kartę filmu,\n - tuzamosc.pl,\n - Zamojski Dom Kultury: godziny ze stron szczegółów,\n - Zamojska Akademia Kultury: kalendarz przez API (bez cotygodniowych zajęć) i sala kinowa ZAK,\n - Melodia Smaku (Jazz Club Kosz): kalendarz ze strony,\n - Kino Stylowy: repertuar na tydzień, w aplikacji jako jedna karta dziennie,\n - KS Hetman Zamość: mecze u siebie,\n - Kronika Tygodnia: festyny i pikniki w powiatach,\n - Super Tydzień Chełmski: Chełm i Krasnystaw,\n - Krasnostawski Dom Kultury.\n- Tytuły filmów z repertuarów pisanych wersalikami dostają poprawną wielkość liter od AI (z cache).\n- Nie da się pobierać automatycznie: Arabeska (ogłasza tylko na Facebooku i Instagramie). Takie wydarzenia dodajesz przyciskiem ＋.\n- To samo wydarzenie z kilku stron jest scalane w jedno. Decyduje ten sam dzień, zgodna godzina i podobny tytuł.\n- Wydarzenia, których reguły nie przypisały do kategorii, klasyfikuje AI (`std/openai`, gpt-5.4-nano). Wystarcza darmowy limit Val Town.\n- **`cron/digest.ts`** codziennie o 8:00 wysyła push na telefony (Twoje „Idę” są na początku) i mail do właściciela. W piątek dochodzi zapowiedź weekendu i ostrzeżenia o źródłach, które przestały działać.\n- **Dodawanie ręczne** (przycisk ＋, wymaga PIN-u): wklej tekst z plakatu, posta z FB albo link, a AI wypełni formularz.\n- Stan źródeł: `/api/status`.\n\n## Zmienne środowiskowe\n\n- `ADD_PIN`: PIN do dodawania i ukrywania wydarzeń.\n- `VAPID_PUBLIC_KEY`, `VAPID_PRIVATE_KEY`: klucze Web Push. Po zmianie trzeba ponownie włączyć powiadomienia na telefonach.\n- `OPENAI_API_KEY` (opcjonalnie): własny klucz, jeśli darmowy limit Val Town okaże się za mały.\n\n👉 Add ADD_PIN here: https://www.val.town/x/dominik1/co-w-zamosciu/environment-variables?key=ADD_PIN\n\n## Struktura\n\n- `index.ts`: serwer Hono (strona, manifest, ikony, service worker, API, pliki .ics)\n- `backend/adapters/*`: parsery poszczególnych stron\n- `backend/sources.ts`: rejestr źródeł i przebieg zbierania\n- `backend/db.ts`: SQLite (wydarzenia, źródła, subskrypcje push, cache AI)\n- `backend/normalize.ts`: daty w strefie Europe/Warsaw, kategorie, miejscowości, deduplikacja\n- `backend/llm.ts`: AI do odczytu tekstu i klasyfikacji\n- `frontend/`: interfejs React, service worker, powiadomienia\n- `scripts/test-adapters.ts`: próbny przebieg parserów bez zapisu (do diagnozy, gdy strona zmieni układ)\n\nNowe źródło dodajesz jako adapter w `backend/adapters/` i wpis w `SOURCES` w `backend/sources.ts`.\n",[149],"42cea312-1aaf-4642-b2da-e3bba05e69b9","CHANGELOG.md","01a09cbf-66da-7600-85d1-72302458f448",1,["D",1789336184443],"# 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
