A cron job scrapes the fixtures page every hour, renders an\n`.ics` feed, and caches it; an HTTP endpoint serves that cache.\n\nEverything identifying — which club, which team, which URL — lives in environment variables, so this\nsource can stay public.\n\n## The feed\n\n```\nhttps://.val.run//calendar.ics the calendar itself\nhttps://.val.run/ a page with a webcal:// subscribe link\n```\n\n`FEED_TOKEN` is a secret first path segment: the feed needs no login (so Apple Calendar can refresh\nit unattended) but can't be found by guessing the hostname. Anything without the token — the bare\nhostname included — gets a bare `404`.\n\n## Configuration\n\nThree environment variables, all required; the val throws a named error if one is missing.\n\n| Variable | What it is |\n| --- | --- |\n| `FULLTIME_QUERY` | The query string from a Full-Time fixtures URL. This is what pins the feed to one team — copy it from the address bar after filtering to the team on the site, keeping `selectedSeason`, `selectedTeam` and `selectedRelatedFixtureOption`. |\n| `TEAM_NAME` | The team exactly as Full-Time spells it. Used as the calendar's name, and to re-find the team's id after a season rolls over. |\n| `FEED_TOKEN` | Secret path segment, e.g. `openssl rand -hex 16`. Changing it changes the feed URL, so every device has to re-subscribe. |\n\nTo point this at a different team, change `FULLTIME_QUERY` and `TEAM_NAME`, then delete the\n`fixture-ids` blob (or just run `scrape.ts`, which re-derives the ids when the old ones return\nnothing).\n\n## How the pieces fit\n\n| File | Role |\n| --- | --- |\n| `config.ts` | Reads the environment and builds Full-Time URLs |\n| `fetchPage.ts` | Fetches a Full-Time page past its Cloudflare WAF |\n| `parse.ts` | Fixtures table → `Fixture[]`, plus reading the page's own dropdowns |\n| `ics.ts` | `Fixture[]` → iCalendar text |\n| `refresh.ts` | Scrape → parse → render → cache in blob storage |\n| `scrape.ts` | Interval val, hourly on cron `17 * * * *` |\n| `main.ts` | HTTP val: serves the cached feed and the setup page |\n\n## The one thing to be careful about\n\n**`fulltime.thefa.com` blocks requests by their shape, not by IP.** Measured behaviour:\n\n- HTTP/1.1 with a browser `User-Agent` → `200`\n- HTTP/2, any headers → `403` \"Attention Required!\"\n- A `curl` or `python-requests` `User-Agent` → `403`\n- `/displayFixture.html` (per-fixture detail) → `403` for every client that isn't a real browser\n\nDeno's `fetch` negotiates HTTP/2 on Val Town and so gets blocked. `fetchPage.ts` therefore speaks\nHTTP/1.1 by hand over `Deno.connectTls` with ALPN pinned to `http/1.1`, and keeps two `fetch`-based\nfallbacks behind it. **Replacing that with a plain `fetch()` silently breaks the hourly scrape** —\ncheck `get_logs` for which rung succeeded (`fetched via raw-tls-http1.1`) before suspecting the\nparser.\n\n## What the calendar contains\n\nOne event per *upcoming* fixture — a match drops out of the feed once its date has passed.\n\n- **Title** `Home Team v Away Team`\n- **Location** the venue as Full-Time lists it (a name only; addresses live on the blocked detail\n pages, so each event links to its fixture instead)\n- **Notes** `Type:`, `Competition:`, a `Status:` line when there is one, then the fixture's URL\n- **Duration** kick-off plus `MATCH_DURATION_MINUTES` (60)\n- **Times** `Europe/London`, with a `VTIMEZONE` so BST and GMT both resolve correctly\n- A fixture with no confirmed kick-off becomes an all-day event; one marked postponed, cancelled or\n abandoned gets `STATUS:CANCELLED`, which Apple Calendar strikes through\n\nEvent `UID`s come from Full-Time's own fixture ids, so rescheduling a match moves the existing event\nrather than creating a second one.\n\n## Caching\n\n`refresh.ts` writes `{ ics, contentHash, fetchedAt, … }` to the val's blob storage under\n`calendar`. Two details worth knowing:\n\n- A failed scrape never overwrites a good calendar — the error goes to a separate `last-error` blob\n and shows on the setup page, while subscribers keep the previous feed.\n- The feed is only re-rendered when its content actually changes (the hash ignores `DTSTAMP`), so\n `ETag`s stay stable and devices get `304`s instead of re-downloading an identical calendar.\n\n`main.ts` also refreshes on demand if the cache is more than 90 minutes old, so a missed cron run\nheals itself on the next request, with one in-flight refresh at a time.\n\n## Working on it locally\n\n```sh\ndeno check --allow-import *.ts # scrape.ts needs Val Town's Interval global, so it fails here\n```\n\n`parse.ts` and `ics.ts` are pure functions over a saved copy of the fixtures page, which makes them\neasy to test without touching the network. On the platform, use `run_file` on `scrape.ts` and read\n`get_logs` rather than waiting for the cron.\n\n## Limits\n\n- One page of fixtures (`itemsPerPage=100`); `parse.ts` logs a warning if it ever hits that cap.\n- No venue addresses, referees or match reports: those only exist on `/displayFixture.html`.\n- Anyone with the feed URL can read the fixture list, so treat it as private.\n",[],[118],"7b26af41-1f4e-46b0-b7d5-0e12bcdf544a",["D",1789467005299],"deletedAt","legacyEnvVars","privacy","public","httpPrivacy","description","Subscribable ICS calendar for an FA
