How do I develop node js on localhost whilst connecting to remote mongo db

问题

I'm using OpenShift with node js and mongo db.

I'd like to develop updates locally and then push them to the server.

How can I develop node js locally and connect to a remote mongo db.

I've tried port forwarding. This forwards everything for some reason so runs node js server instance. Which is no good. I want to run the localhost node js.

rhc port-forward appname

This port forwads just mongodb, but if I then run node js in a separate terminal, it's unable to connect.

rhc port-forward appname -s mongodb

Do i even need port forwarding, or will the correct mongo db connection string solve this?

Hope somebody clever out there knows the answer.

回答1:

Ok, solved this.

First enable port forwarding for just mongo db.

rhc port-forward appname -s mongodb

Use a local db connection string

mongodb://admin:ABCDEFGHIJ@127.0.0.1:27017/database‌​name

Run node

node server.js

Port forwarding will forward just mongo db via localhost to it's remote location.
