MongoDB 2 driver node

[Oren Zomer]

https://www.npmjs.com/package/node-red-node-mongodb2

Based on: http://mongodb.github.io/node-mongodb-native/2.0

This is a beta version. Not all operations were tested.

Let me know what you think,

Oren

Hi Oren,

thanks for sharing this.

Can you describe what this provides above the existing mongo nodes? Is there a reason this needs to exist as a separate node, rather than contribute back to the existing one?

We do politely request that 3rd party nodes use the name prefix "node-red-contrib-" to avoid confusion with ones maintained by the project - http://nodered.org/docs/creating-nodes/packaging.html

Renamed to: https://www.npmjs.com/package/node-red-contrib-mongodb2

The node-red-contrib-mongodb2 supports all the collection operations of api2 (for example: findOne, updateMany, etc.).

The input msg.payload can be an array of parameters to pass to the operation.

Update operations also have an "output" - for example, in case of upsert, I want to know if the operation created a new document or updated an existing one, so I could react on the first insertion differently than on the following updates.

I also separated the "find" operation (which returns a cursor) to "find.toArray" (sends a single message with an array of the results) and "find.forEach" (sends a message for each result).

Hi Oren,

I am unable to install the mongodb2 nodes on my MAC. May you please guide how to do the same.
It is showing me in the node-modules folder but when i run the node-red , it does not show the node there.

Regards,
Surbhi

If node-red-contrib-mongodb2 is inside node_modules and you cannot even see the nodes, I don't believe it's a problem with node-red-contrib-mongodb2.

Can you see any special error logs?
