问题 I have a module that is supposed to run on the client, but I'm testing it on Node.js, so I'd like to make $.ajax to work.

问题 This question already has answers here : How to list all MongoDB databases in Node.js? (3 answers) Closed 4 years ago . I have seen answers on C# and Java but not able to find anything on NodeJs. I have tried using cmd shell in Windows to get the required output but no luck.
