variable property
Figure 1 - variable property

Set a variable in one function, and use it elsewhere​

The following code stores the ID of a selected customer in the system so it can be used later.
Store customer ID
function SetCustomerID(five: Five, context: any, result: FiveError) : FiveError {
    five.setVariable("selectedCustomerID", customerID);
    
    return five.success(result);
}

Backend function - use the same variable​

Before calling the

CustomerOrders()
function, the selected ID is set using
setVariable()
 in the
SetCustomerID()
function.

The following code uses the ID of a selected customer to process customers orders.
Process customer orders
function CustomerOrders(five: Five, context: any, result: FiveError) : FiveError {
    const customerID = five.getVariable("selectedCustomerID");

    if (!customerID) {
        return five.createError("No customer selected");
    }

    five.log("Loading orders for customer: ", customerID);
    return five.success(result);
}
