Great for development. Say you want to share the database with someone else in a remote location.
package.json file with
npm init, if you don’t have one already.
Enter and modify the following line in that file (replacing all the
"meteor": "MONGO_URL=mongodb://<USER>:<PASSWORD>@<SERVER>:<PORT>/<DB> meteor"
For meteor to start using your remote MongoDB start meteor with
npm run meteor
If you are looking for a way to remove an item from mongodb which is contained in an array the following stackoverflow post has the answer.
