Question

MongoDB and Mongoose Question

I have a database-initializer.js file that initializes a MongoDB database. In it is this line let db = client.db('myDatabase');

I want to have another file which is my server.js file (that uses Node.js and express to create a server and handle requests) and in that file I want to use mongoose and connect to the database initialized by the database-initializer.js file, would I do this by the following line:

var dbURL = 'mongodb://localhost:27017/myDatabase';

mongoose.connect(dbURL);

Would that be the name of the database I create? Would it work as intended?

Or would the URL have to be:

var dbURL = 'mongodb://localhost/myDatabase';

Thank you, I am a little confused.

Answer 1

if you are using mongoose to connect to the data base

mongoose.connect('mongodb://localhost:27017/myDatabase', {useNewUrlParser: true});

where,

localhost - if you are running mongodb on the same machine, if mongodb is in different machine use the pulic ip of that machine(like 192.168.10.10)

27017 - is the default port that mongodb runs on a machine, it can be changed though(if you have changed use the changed port instead of 27017, else leave it as it is...)

myDatabase - is your database name, you can put any name that you wanted as your data base name here, and there is no need for that database to be already created, mongodb will create automatically for you if it is not created, if the database exist with that name, it will use that database without creating a new one.
