RPC event subscription problems

What happened:
When subscribing to events via websocket RPC, I'm getting a single empty JSON object as a response, and no event responses.

What you expected to happen:
An error if I'm using the pubsub query incorrectly, otherwise I should see event data.

How to reproduce it (as minimally and precisely as possible):

main.js:

let Tendermint = require('tendermint')
let rpc = Tendermint('ws://localhost:46657')

rpc.subscribe({ query: "tm.events.type = 'NewBlock'" }, (err, event) => {
  console.log(err, event)
})

$ npm install tendermint
$ node main.js

Anything else do we need to know:
I can't find docs for this, but a cursory reading of the code made me think this was the correct new way to subscribe.

Just tested and it works with "tm.event = 'NewBlock'"

Please re-open if you still having trouble.

If i am using curl to do this what would it look like?

[mappum]

@minhxtran You won't be able to do this through curl, since event subscription only works through Websocket and not plain HTTP.

You may want to look at the js-tendermint repo.

Thanks for the clarification.
