Paths and Reshaping

Branchline reads from INPUT (or $) and builds new objects with OUTPUT. Use dot paths and array access to grab what you need.

Goal

Reshape an order payload into a compact shipment record.

Program

TRANSFORM OrderShipment {
    OUTPUT {
        orderId: INPUT.order.id,
        customerId: INPUT.order.customer.id,
        shipTo: INPUT.order.shipping.address,
        items: INPUT.order.items,
    };
}

Tips

• Prefer direct paths for clarity.
• Build new objects with explicit keys so downstream systems get stable schemas.
