I want to run a private node, and use it to receive realtime unconfirmed transactions data into my nodejs script.
How do I go about this?

Either you use some nodejs library which would give you a high level wrapper for the bitcoin core api getrawmempool, or make your script hit your local bitcoin instance in the json-rpc format to get the memorypool data your node has.
The memory pool is basically where the transactions stay before getting confirmed in a block. So your script needs to run in regular intervals of time to keep track of the changes too.
url: http://<username>:<password>@localhost:18332/
post data:{"jsonrpc":1,"id":"curltext", "method":"getrawmempool", "payload":[]}
The username and password is checked from the bitcoin.conf file in the .bitcoin folder. Change the port number to 8332 in case you are running the mainnet daemon.

Ah okay, I was hoping for some sort of a websocket connection/ ethereum .filter() function sort of a thing. Thanks though!– SatonamoCommented Jul 1, 2017 at 12:40
