How to connect to external MongoDB instance in Meteor?

Question

I would like to find out how to connect to an external MongoDB instance in Meteor.

I have added this environment

Meteor.startup(function () { 
process.env.MONGO_URL = 'mongodb://[UN]:PW]@[host]:[port]/meteorTest'
});

but still the data is coming from the local database.

I want to move all the collections from my local db to this external db. I read all the tutorials, its all telling me to setup this evn variable but nothing really working. How do I test whether its connected or not?

In my own experience; I have needed to set the environment variable before starting the meteorjs server app. To do this you will need to pass the environment variable on the command-line as you invoke meteor or preset the environment for the profile that is running the meteor app on your system.

So you would start your app with this kind of a command:

MONGO_URL='mongodb://user:password@remote.domain.com:12345/' meteor

You should also make sure that the mongodb is reachable and that your user credentials are correct! I am assuming you are trying to run meteor on your local machine using a remote mongodb instance.

On Windows

You will have to create a batch file in your meteor application folder to invoke the environment variable. There is an example of this here: https://stackoverflow.com/a/29833177/1997579
