The CloudFormation resource specification used by @aws-cdk packages
npm install @aws-cdk/cfnspecTo update the CloudFormation spec, you can run bump-cfnspec.sh from a clean repo, as so -
``console`
./scripts/bump-cfnspec.sh
If you wish to only update the CFN spec, make sure to install all dependencies and build the cfnspec module,
and then you can just run:
`console``
yarn update
