Listen to events from a already deployed smart contract

[ripern]

I'd like to listen to a specific event for a smart contract that is already deployed on Rinkeby. Could you show a few lines of example code for doing that?

Cheers

Heyo, yes, so I would setup a contract object and then use either getLogs or onEvent. getLogs will scan through the entire chain from where you specify the fromBlock blocknumber and toBlock blocknumber. The log data will then be decoded and will be returned. I would use getLogs initially then use onEvent for keeping up to date. I'll get an example up tomorrow.

An example would be awesome! I'm a bit unsure about the "setting up an EthContract object for an existing contract" part especially. Thanks!
