getSSMParamViaCustomResource

This allows cross-account/region querying of Systems Manager Parameter Store entries from within CDK code which can then be used within the same stack. This uses behind the scenes the AWS CDK Provider framework to resolve via custom lambda's the call in the appropriate account location.

Example usage

YourStack.ts

import { CDKCustomResourceUtil } from 'aws-cdk-lib-util';
...
export class YourStack extends Stack {
  constructor(scope: Construct, id: string, props: IYourStackProps) {
    super(scope, id, props);
    
    const {
      projectName,
      stackEnv,
      functionName,
      targetParamName,
      targetAccount
    } = props;
    ...
    const parameterValue = const CDKCustomResourceUtil.getSSMParamViaCustomResource({
      scope: this,
      projectName,
      stackEnv,
      functionName,
      account: targetAccount,
      paramName: targetParamName,
    });
    ...
  }
}
