Add a when clause to the contributed explorer view such that it is only activated when the workspace has a package.json file #117950
Description
As you can see below, I don't have a package.json file in my workspace. I am working in a Python project. This extension is still contributing its view however.
Would it be possible to have the extension only contribute its view when a package.json is found at the root of the workspace?
This feature is talked about here microsoft/vscode-java-test#793 (comment).
