Again, I won't cover installation of the server software. Please refer to the official installation instructions(h t t p s ://d o c s . m o n g o d b . c o m /m a n u a l /i n s t a l l a t i o n /) in order to get a MongoDB server up and running on your machine.
If you have Docker installed on your machine, the quickest way to get a MongoDB server up and running is this one-liner:
docker run --rm --name mongo -p 27017:27017 -d mongo:3.4
See h t t p s ://h u b . d o c k e r . c o m /_ /m o n g o / for more details.
Once this is done, create a new project folder called mongodb-test, and in there create an initial package.json as follows:
{ "name": "mongodb-test", "version": "0.0.1", ...
