How to connect to external MongoDB instance in Meteor?

I don't like to use big repeating command and I was searching for a solution where I will be setting a variable embedded with something so every time I start my meteor app; the MONGO_URL will set to environment automatically. So this what I did:

In the package.json file I replaced the start parameter as below:

"scripts": {
    "start": "MONGO_URL=mongodb://username:password@host_url:portnumber/dbname meteor run"
  },

Now every time I want to run my app; I run npm start instead of meteor or meteor run

Note: there is a disadvantage with that. Your db credentials will be exposed if you put your db credentials to package.json file and add this file to version control.

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:[email protected]: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
