$ npm query ":type(git)" | jq 'map(.name)' | xargs -I {} npm why {}

try on your machine

Let's break down the command step by step:

npm query ":type(git)": This command uses npm to query for all packages of a specific type, in this case, packages that are hosted on Git repositories.
|: This vertical bar (pipe character) is used to take the output from the previous command and pass it as input to the next command.
jq 'map(.name)': The output from the previous command is piped into jq, a tool used for parsing and manipulating JSON data. The map(.name) part tells jq to extract only the name field from each object in the JSON response.
|: Again, this pipe character is used to pass the output to the next command.
xargs -I {} npm why {}: xargs is a command that reads items from standard input and executes a command using those items as arguments. -I {} specifies a placeholder {} that will be replaced with each line of input received. In this case, each package name is passed as an argument to npm why, which is a command to display information about why a package is installed.

So, the overall purpose of the command is to query npm for all Git-hosted packages, extract their names, and then use npm why to find out why each package is installed.
