Brackets High Limit League

A league site and a Telegram bot for a Sleeper fantasy football league, built on the free Sleeper API (no API key needed).

The site (public/ + api/)

Static pages plus one small serverless function. No build step.

Page	What it does
Home	Hero, results ticker, league stats, this week's matchups, power top 8, awards, latest moves, hot free agents
Standings	League table with form, weekly trend, power rankings and a luck index (real wins vs all-play expected wins)
Scores	Any week's scoreboard, click a matchup for both lineups; auto-refreshes while games are live
Lineups	Lineup check: flags starters who are Out/IR/Questionable or empty slots, suggests healthy bench swaps and spots bench players out-scoring starters. Read-only — each "Fix it in Sleeper" button opens the app
Draft	Full snake board, replay the whole draft pick by pick, position filter, tap any pick for details
Draft > Value & grades	Biggest steals and busts, and a draft grade per team (starter points its own picks delivered)
Draft room	Paste any Sleeper draft ID: live board (polls every 4s), on-the-clock card with timer, best available, your roster needs, "you're 2 picks away" alerts. Finished drafts can be simulated pick by pick
Awards	Weekly awards and season superlatives, plus a button that copies the recap for the group chat
Moves	Every trade, waiver and free-agent move, filterable
Market	Most added / dropped players on Sleeper, and who owns them in your league
Team pages	Roster with season points, weekly scoring chart, results, draft class, lineup check, and "Make this my team" (remembered on that device — no login, personalization only)

Open /?league=<league_id> to point the site at a different league.

Can people change their lineup here? No. Sleeper's public API is read-only and has no login, and lineups can only be changed inside Sleeper. The site links straight into Sleeper (league, team, matchup and draft pages) wherever a change is needed.

The hero trophy was generated with Meshy (text-to-3D) and lives in public/assets/. Everyone sees the 88KB trophy.png; wide screens without data-saver upgrade to the interactive 3D trophy.glb (7.6MB) once the page is idle, via <model-viewer>. Shrinking the GLB (for example with gltf-transform optimize) would make that upgrade lighter.

Deploy to Vercel

1. Import this repo in Vercel. Leave the framework preset as Other; vercel.json already sets the output directory to public.
2. Deploy. There are no environment variables to set for the site.

api/players.js trims Sleeper's 15MB player file to about 130KB and lets Vercel's CDN cache it for six hours, which keeps us inside Sleeper's "fetch the player list at most once a day" request.

Run locally

npm run dev   # http://localhost:3000

The Telegram bot (src/)

Commands: /standings /scores /roster <team> /draft [team|id] /trending /moves /awards /luck /help. It also posts on its own: every new trade or waiver move, and the awards recap when a week finishes.

1. Create a bot with @BotFather and copy the token.
2. Add the bot to your group and send /chatid to get the group's id.
3. Copy .env.example to .env (or set real environment variables on your host) and fill in TELEGRAM_BOT_TOKEN and TELEGRAM_CHAT_ID. Never commit the token.
4. npm run bot. It uses long polling, so it needs a host that stays running (not Vercel serverless).

Try any command without Telegram: node src/cli.js standings.

Notes

• Data comes from the public Sleeper API, which is read-only. Nothing here can make picks or change a lineup.
• Draft "value" and "grades" are computed from this league's real points, not from an external ranking.
• Best-available in the draft room is ordered by Sleeper's popularity rank, not an expert ranking.
