XI Draft

An unofficial, browser-based football squad draft and match simulator. Build a 15-player squad from the Turkish Süper Lig, Europe's top five domestic leagues and UEFA competition clubs, then play friendlies or a simulated cup campaign.

Play locally: python3 -m http.server 8000, then open http://localhost:8000.

Features

• Draft an 11-player starting lineup in a 4-3-3 or 4-2-3-1, then choose a goalkeeper, defender, midfielder and forward for the bench.
• Get five randomized options per pick, with more weight given to players rated 76 or higher.
• Play simulated matches in 15-minute periods, select tactics and make up to five substitutions at breaks. Substituted players cannot return.
• Enter a Süper Lig cup or a UEFA Champions League, Europa League or Conference League simulation.
• Review live match scorers, overall campaign top-scorer and top-assister tables, and a separate list of your own squad's contributions.
• Keep drafts, match progress, substitutions and tournament history in browser localStorage; optional Supabase accounts can sync progress when configured.
• Install the responsive app as a Progressive Web App on supported devices.

Player and competition data

This repository includes a generated 2026/27 player and competition snapshot. Where present, player ratings are taken from EA's public FC 27 ratings page. Players without an EA match have estimated ratings, which are labeled in the game. EA's ratings page and bundled portrait URLs may not reflect the final in-game release; roster and league snapshots can also be incomplete or change during the season.

UEFA entrants are based on the published participant snapshot. Fixtures, match results, standings and player goals/assists are simulated for gameplay and are not official records. Season-table context is calculated from available ESPN score feeds, not official standings.

See GLOBAL-DATA-SOURCES.md for source details, known limitations and snapshot regeneration instructions.

Run and deploy

This is a static site: there is no package install or build step.

1. Start a local server with python3 -m http.server 8000.
2. Visit http://localhost:8000 in a browser. The service worker, local saves and responsive layout can be tested from this origin.
3. To deploy, publish the project directory with a static host such as Netlify. The included _headers file provides the site's HTTP security headers; verify them on the deployed site.

Quick smoke test

Start a draft, choose a formation and complete all 15 picks. Reload the page to confirm the squad is restored, start a friendly, play through a 15-minute period and make a substitution at the break. Reload again to confirm the match clock, lineup and substitution are retained. The app stores this state under xi-draft-superlig-2026-27-v3 in browser local storage.

Optional Supabase accounts

Guest play and local saving work without an account. To set up cloud saves:

1. Create a Supabase project and run supabase/schema.sql.
2. Configure Supabase Auth email sign-in, confirmation URLs, rate limits and allowed origins; review row-level security and account deletion behavior.
3. Copy supabase-config.example.js to supabase-config.js, then set the Supabase project URL and publishable client key. supabase-config.js is git-ignored intentionally.
4. Keep localTestMode false for public hosting. Set legalDocumentsReady true and provide the actual terms/privacy version identifiers only after the legal pages are complete and reviewed.

The browser key is public by design; never add a Supabase service-role/secret key, database password or other credential to browser code or a public repository. Read SUPABASE-SETUP.md before enabling accounts. The bundled privacy and terms pages still contain draft placeholders and are not ready for public account registration; complete the publication checklist before enabling cloud sign-up.
