@nosslabs/iapIn-app purchases for Capacitor 5

Thin orchestrator. Server-side validation via Attesto.

🛡️

Safety-first purchase flow

Acknowledge native transactions ONLY after the backend confirms validation. No phantom grants if the network drops mid-purchase.

🔌

Transport-agnostic

HTTP/JSON default. Swap in a custom BackendAdapter for GraphQL, gRPC-web, Firebase, or Supabase without changing call sites.

🧬

Generic entitlement type

Bring your own TEntitlement. The library validates the base shape; your domain fields ride along through caches, events, and responses.

♻️

At-least-once recovery

Killed-mid-purchase transactions persist to local storage and re-verify on next launch. Users never end up paying for nothing.

⚡

Reactive events

Subscribe to entitlements-changed and wire a Pinia or React store in 5 lines. Frozen entitlement objects prevent accidental mutation.

🌐

Web-friendly

Web platform is no-op for purchases (rejects with PLATFORM_NOT_SUPPORTED). Cached entitlement reads still work for dev workflows.
