TypeScript: Variable 'require' must be of type 'any', but here has type 'NodeRequire'.

After loading a solution for a code review, I was welcomed by the following error message:

Variable 'require' must be of type 'any', but here has type 'NodeRequire'.

Google brought me to the following GitHub issue; https://github.com/Microsoft/TypeScript/issues/16298 where the proposed solution was as simple as beautiful:

There must be another definition of require somewhere.

And indeed, after triggering a search on my solution I found another ‘declare var require’ somewhere in a typedefinition file. After removing it, the error disappeared (and everything still worked).

A single pod produces about 11 Kg CO2eq per year( here the calculation). Reason enough to give it a try! Installing kube-green in your cluster The easiest way to install the operator in your cluster is through kubectl. We first need to install a cert-manager: kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.14.5/cert-manager.yaml Remark: Wait a minute before you continue as it can take some time before the cert-manager is up & running inside your cluster. Now we can install the kube-green operator: kubectl apply -f https://github.com/kube-green/kube-green/releases/latest/download/kube-green.yaml Now in the namespace where we want t
