Hyperledger Fabric query system chaincode using node SDK

Question

My end goal is to get all existing channels. For that, I would have to query CSCC as suggested in this answer.

However, after creating the request, I would need a client object on which I would call the queryByChaincode method. When I try to create a channel instance using client.newChannel(''), the code throws an error saying that channel name is mandatory.

Now how do I query an SCC using node sdk without a channel instance?

Answer 1

The Fabric Node SDK actually provides a method on the client class which will retrieve all the channels to which a peer belongs: client.queryChannels(peer, useAdmin)
