I am struggling with inputs / outputs or just my general understanding

let agwConfig: azure.network.ApplicationGatewayArgs = {
        name: agwName,
        resourceGroupName: resourceGroup.name,
        autoscaleConfiguration: {
                    minCapacity: appGatewayAutoScaleMinimumInstanceCount,
                    maxCapacity: appGatewayAutoScaleMaximumInstanceCount 
        }
        //... more code here
   }

If I wanted to optionally have the autoscaleConfiguration not be set to anything, how can I do that? I tried clearing it after with

if (!useAppGateayAutoScale)
    {
        agwConfig.autoscaleConfiguration = null;
    }

but it gives me an error that the property is readonly so it can not be changed

I’m thinking you can set a variable before agwConfig that defines the autoscaleConfiguration object and then use that value in the agwConfig setting. E.g.

const autoscaleConfig = (useAppGaeayAutoScale ? {minCapacity: appGatewayAutoScaleMinimumInstanceCount, maxCapacity: appgatewayAutoScaleMaximumInstanceCount} : {})

let agwConfig ... = {
   ...
autoscaleConfiguration: autoscaleConfig
}

close! I think this works:

const autoscaleConfig = (useAppGatewayAutoScale ? {minCapacity: appGatewayAutoScaleMinimumInstanceCount, maxCapacity: appGatewayAutoScaleMaximumInstanceCount} : undefined)
