API

node = IndyReq(conf)

• conf.host the host string i.e. 10.0.0.2
• conf.port the port of the indy node you want to connect to
• conf.serverKey the Buffer of the node's curve25519 key
• conf.timeout (optional) how long to wait for responses in ms. Default is 1min.
• conf.genesisTxn instead of host+port+serverKey you can simply pass a line from the genesis transaction to the node you wish to connect to.

p = node.send(data)

Send a request to the server. This will set a reqId for you and track it. This returns a promise that will resolve when the response is recieved.

node.ping()

Send a ping to the indy node

node.close()

This closes the zeromq socket. Any pending requests that have not yet been resolved will be rejected with a 'Closed' error.

node.on('error', function(err){})

When an error not tied to any known request occurs.

node.on('pong', function(){})

When a pong is recieved from the indy node.

node.on('close', function(){})

When node.close() is called.
