OpenFUT Agent f70cf4415c wip(core): preserve local broad Core refactor + inventory service
Divergent development line off origin/main (11a811d): a broad refactor across
routes/services/models/app + a large integration_test expansion (+1000), plus an
untracked game-independent inventory query service and Docker files. Preserved
verbatim before moving the canonical Core checkout to the committed migration
trunk (66c88fb). Reconciling this refactor with the migration trunk is a separate
user decision; nothing here is lost.

Prerequisites

  • Rust (stable, 1.80+) — install via rustup
  • SQLite 3 — usually pre-installed on Linux/macOS

Recommended tools:

rustup component add clippy rustfmt

Setup

git clone <repo-url>
cd openfut-core
cp .env.example .env
cargo build

Running locally

cargo run

The server starts at http://127.0.0.1:8080 by default. Logs appear in the terminal. On first run, the SQLite database is created and all migrations are applied automatically.

Running tests

cargo test

Tests spin up a full in-process server against an in-memory SQLite database — no setup required and nothing is written to disk.

Code style

All PRs must pass before merge:

cargo fmt --check    # formatting
cargo clippy -- -D warnings   # lints
cargo test           # full test suite

Auto-fix formatting with cargo fmt.

Adding card / pack / objective data

See MODDING.md for the data file schemas. No Rust code changes are needed to add new cards, packs, objectives, or SBC definitions.

Branching & pull requests

  • Create a branch from main: git checkout -b feat/my-feature
  • Keep PRs focused — one feature or fix per PR
  • PR description should explain why, not just what

Design constraints

  • No online multiplayer. This is an offline local backend only.
  • No copyrighted assets. All card data in data/ must be original.
  • No real EA services. Do not hardcode or reverse-engineer EA endpoints.
  • Game-independent core. openfut-core must stay game-agnostic; FIFA-specific logic belongs in the emulation layer (fifa17-recon/).
