Leek Nook

A cozy little window on CyberLeek's market cap (Solana, mint ApZuxdpzMrbEYTGEzeY9afh5pj9d6qPRJCTgQYiipbKg), with a bell that rings your phone when it reaches $30M (or any goal you pick).

Open it: https://umershahid1903.github.io/leek-nook/

On your Android phone

1. Open the link in Chrome → tap Add it (or ⋮ → Add to Home screen → Install).
2. Open Leek Nook from the home screen → Hang the bell → allow notifications.
3. Within ~5–15 minutes the bell card says "Hung. The night watch has this phone…". There's no popup for that.

What rings: one notification when the cap reaches your goal, and only while the nook is closed. If it's open, the leek blooms and petals fall instead. Test ring shows what the notification looks like.

How it works

• Market cap = DexScreener's live price × the exact token supply on the Solana blockchain (getTokenSupply; mint authority is revoked, so it can only shrink). The night watch reads the supply and publishes it as supply.json on the bell-state branch, because public Solana RPCs refuse web pages. The page falls back to GeckoTerminal's copy of the on-chain number.
• The page (index.html, app.css, app.js) refreshes every 10 s while open and shows the cap with a bar toward the goal.
• The night watch (.github/workflows/bell.yml → bell/bell.mjs) runs on GitHub Actions every ~5 minutes. It has two clocks. Each look queues the next one behind the pause environment's 4-minute wait timer, which holds the job without a runner. The */5 cron is a backup that restarts the chain if it ever stops. (The cron alone never fired in the repo's first two hours.) It reads the cap and the last 90 one-minute candles, so a spike between two runs still counts (candle bodies only, not single-trade wicks). It then sends one Web Push to every armed bell that reached its goal. The service worker (sw.js) shows it only if no Leek Nook window is on screen. A bell rings once, then re-arms after the cap falls under 90% of the goal.
• The mailbox (mailbox.js) is how the phone tells the night watch where to ring. The phone seals its push address with the watch's public key and posts it to a public ntfy.sh topic. Only the Actions secret can open it. The watch keeps the sealed notes in state.json on bell-state, filed under a hash of each phone's secret device id. The page reads that file to show "picked up".
• Self-healing: each time the nook opens it checks its push address. If Chrome dropped it (site data cleared, notifications toggled, app installed after hanging), it sends a new one. If the watch hasn't picked it up after 40 minutes, it sends the note again.
• Secrets (repo → Settings → Secrets → Actions): VAPID_PRIVATE_KEY, MAILBOX_PRIVATE_JWK. The public halves are in config.js.

Tests (local, nothing touches the real bell)

cd bell && npm ci && cd ..
node tests/bell.e2e.mjs   # real push through Google FCM into a headless Chrome, test keys and topic
node tests/screens.mjs    # phone-size screenshots, light and dark → tests/out/
node tests/perf.mjs       # 6× slower CPU, counts tasks over 50 ms
node tests/live.e2e.mjs   # LIVE: hangs a test bell on github.io, runs the real watch, takes it down
node tests/serve.mjs      # serve at http://localhost:18777/leek-nook/

Changing things

• Goal, coin, re-arm level: config.js.
• Icons: edit the drawing in tools/make_icons.mjs, then node tools/make_icons.mjs.
• New keys: node tools/make_keys.mjs --force, update both secrets, push. Phones must hang the bell again.
• Every release: bump VERSION in app.js and sw.js.
