Installing external module using npm

Question

debug icon showing in package.json but not quite sure what it means or how to fix it because when I copied and pasted code to stackoverflow, icon didn't show.

Created a package.json file through terminal and code should be as below, but my editor is showing me the debug icon as seen in the image and I'm not quite sure what it means or what todo.
