BetFair Stream API App (Tauri)

Cross-platform Tauri v2 desktop app that connects to Betfair Exchange APIs:

• Auth (Identity): credentials handled in Rust; session token stays in Rust
• JSON-RPC (Sports/Account/Heartbeat): UI calls Rust via Tauri invoke()
• Stream API: Rust maintains the TLS stream and forwards updates to the UI via Tauri events

Repo layout:

• ui/: React/Vite UI
• src/: Tauri (Rust) app core

Prereqs

• Rust toolchain
• Node.js (for the UI)

Dev

Run the UI dev server, then run the desktop app in dev mode:

npm --prefix ui run dev
cargo tauri dev

Build (bundles/installers)

Build platform installers/bundles via the Tauri bundler:

cargo tauri build

The UI production build is executed from build.rs during release builds (set TAURI_SKIP_UI_BUILD=1 to skip if ui/dist is already up to date).

Outputs are written under target/**/release/bundle/ (e.g. .dmg, .msi, .AppImage, .deb).

Configuration

The Betfair AppKey is expected at build time:

• BETFAIR_APP_KEY (set in CI via repository secrets)

Runtime settings are stored by the app; see the UI settings screen.

CI/CD

• CI runs on PRs and pushes to main.
• Releases are built and published when pushing a tag matching v*.
