How can I connect to a remote Bitcoin node?

[michelem09]

It's really hard to understand how to connect to a remote Bitcoin node I have yet. I'm trying with something like this but without success:

var bitcore = require('bitcore-node');
var Bitcoin = bitcore.services.Bitcoin;
var Node = bitcore.Node;

var configuration = {
	network: 'testnet',
	services: [{
		name: 'bitcoind',
		module: Bitcoin,
		config: {
			connect: [{
				rpchost: 'example.com',
				rpcport: 3332,
				rpcuser: 'myuser',
				rpcpassword: 'mypass',
				zmqpubrawtx: 'tcp://example.com:3333'
			}]
		}
	}]
};

var node = new Node(configuration);
console.log(node);

Output is:

Node {
      configPath: undefined,
      errors: { Error: [Function: err], RPCError: [Function: err] },
      log: Logger { formatting: true, debug: [Function] },
      network: 
       Network {
         name: 'testnet',
         alias: 'regtest',
         pubkeyhash: 111,
         privatekey: 239,
         scripthash: 196,
         xpubkey: 70617039,
         xprivkey: 70615956,
         port: [Getter],
         networkMagic: [Getter],
         dnsSeeds: [Getter] },
      services: {},
      _unloadedServices: [ { name: 'bitcoind', module: [Object], config: [Object] } ],
      port: undefined,
      https: undefined,
      httpsOptions: undefined }

And as you can see there isn't any services: {} active.

What am I missing?

@michelem09 this is how we connect to an external bitcoin node (our bitcore-node.json config file):

{
  "network": "livenet",
  "port": 3001,
  "services": [
    "bitcoind",
    "insight-api",
    "insight-ui",
    "web"
  ],
  "servicesConfig": {
    "bitcoind": {
      "connect": [
        {
                "rpcuser": "bitcoin",
                "rpcpassword": "local321",
                "zmqpubrawtx": "tcp://127.0.0.1:28332"
        }
       ]
    }
  }
}

In our case, the bitcoind node is running on localhost. If you specify rpchost it should connect to another address.

Is it possible to configure bitcore node in such a manner to sync with my own coin, so that i can integrate it with insight UI. Please reply. I am stuck here, whenever i hit bitcore-node start command , it starts bitcoind and sync with bitcoin block chain

Hello!

I have the same issue and can't connect to the node wich runnig locally.

I've tried to use configuration like:

{
	"network": "testnet",
	"services": [
		"bitcoind"
	],
	"servicesConfig": {
		"bitcoind": {
			"connect": [{
				"rpcuser": "bitcoin",
				"rpcpassword": "local321",
				"zmqpubrawtx": "tcp://127.0.0.1:28332"
			}]
		}
	}
}

The result is:

/bitcoin/node_modules/bitcore-node/lib/node.js:156
      addToStack(service.module.dependencies);
                               ^

TypeError: Cannot read property 'dependencies' of undefined
    at addToStack (/bitcoin/node_modules/bitcore-node/lib/node.js:156:32)
    at Node.getServiceOrder (/bitcoin/node_modules/bitcore-node/lib/node.js:167:3)
    at Node.start (/bitcoin/node_modules/bitcore-node/lib/node.js:253:28)
    at Object.<anonymous> (/bitcoin/index.js:39:6)
    at Module._compile (module.js:624:30)
    at Object.Module._extensions..js (module.js:635:10)
    at Module.load (module.js:545:32)
    at tryModuleLoad (module.js:508:12)
    at Function.Module._load (module.js:500:3)
    at Function.Module.runMain (module.js:665:10)

Also, I've tried configuration like:

{
	network  : "testnet",
	services : [
		{
			name   : "bitcoind",
			module : Bitcoin,
			config : {
				connect : {
					rpcuser     : "bitcoin",
					rpcpassword : "local321",
					zmqpubrawtx : "tcp://127.0.0.1:28332"
				}
			}
		}
	]
}

And result is only one line in console:

[2017-10-02T14:14:38.156Z] info: Starting bitcoind

What am I doing wrong?

Check your debug.log.

@LordotU Use this code inside config object:

connect: [{
    rpchost: "127.0.0.1",
    rpcport: 18332,
    rpcuser: "bitcoin",
    rpcpassword: "local321",
    zmqpubrawtx: "tcp://127.0.0.1:28332"
}]

@qld-cf Just use the bitpay/bitcore v8.0.0 branch (here), it should work out of the box, let me know if you can't make it work!
