hello guys, I want to use web3.js on backend.
how can I connect to an existing contract to fire its methods?
I have ABI & address, so I pass both to:
var c = web3.eth.contract(ABI).at(addr);
Should I be connected to the contract?
How can I now fire methods?
Is the undergoing way right?
c._eth.MethodName()

Just c.methodName()

It is correct, I am sure, the thing is that I need to connect to the running node, or initialize own. Are there any free nodes I can connect to?
