The whole commerce engine,
laid bare.

Every part of rCommerce is inspectable and typed — from the checkout state machine to the request lifecycle to the hook points you extend. Here's how it fits together.

One core. Every event.

A request flows through the same typed core whether it arrives over the REST API — and every state change fans out as a signed event.

Hook in. Don't fork.

Register typed handlers at defined points in the lifecycle. Your logic runs inside the engine with full type safety — and survives upgrades.

#[hook(after_order)]
async fn award_points(order: &Order) -> Result<()> {
    let pts = order.total.whole();
    loyalty::grant(order.customer, pts).await?;
    Ok(())
}

Sub-10ms responses and 10k+ concurrent connections. Async Rust — no fleet required.

Memory-safe core, parameterised queries, signed webhooks, scoped tokens.

Structured logs, OpenTelemetry traces, and Prometheus metrics in the box.
