Meteor Remote MongoDB

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"
