Node.js counting from database question

Question

So my project is made with MERN stack and it has:
1-"src" folder which contains the front end (a form to fill)
2-"server" folder for the server which contains Models declaration and connection to mongo dB
So, everything is fine but the problem is that I want to write the code which allows me to know the count of filled forms. I tried to use "countDocuments" but I don't know how to set it on my project because of the different folders I have.

Answer 1

path_to_form_data_collection.countDocuments()

This will return number of documents inside the collection
