Static
isChecks if x
is a construct.
Use this method instead of instanceof
to properly detect Construct
instances, even when the construct library is symlinked.
Explanation: in JavaScript, multiple copies of the constructs
library on
disk are seen as independent, completely different libraries. As a
consequence, the class Construct
in each copy of the constructs
library
is seen as a different class, and an instance of one class will not test as
instanceof
the other class. npm install
will not create installations
like this, but users may manually symlink construct libraries together or
use a monorepo tool: in those cases, multiple copies of the constructs
library can be accidentally installed, and instanceof
will behave
unpredictably. It is safest to avoid using instanceof
, and using
this type-testing method instead.
Any object
true if x
is an object created from a class which extends Construct
.
Register SSM Parameters in other regions storing a reference to a resource, which can then be resolved in the other region by reading from the parameter.
Storing the SSM Parameters in the other regions speeds up the resolving of parameters, since we can use CloudFormation SSM Parameters instead of custom resources.
If the resource is in the same region, the resource will be returned like normally in CDK, causing an export/import if cross-stack.
