working on typescript , how can i validate if resouces exists before try to create it. ? [11:50 AM] for example i want to create vpc only where it's not exists:) const vpc = new awsx.ec2.Vpc(vpcName, { numberOfAvailabilityZones: 2 }); [11:50 AM] error: Duplicate resource URN '

do a try catch and use the get function:

awsx.ec2.Vpc.get("name", "urn")

then on the catch you return the created resource

This solution results in your project permanently having to maintain a code path for an unmanaged resource and one for a managed resource. A more sustainable option is to manually import the resource, and omit the get code and exception handling. That way, the only code path is for the managed resource.

I agree. The best practice would be to import the resource. But sometimes resources gets created automatically based on parent resources. So I contained myself to only answer the question.
