How to interact with Janusgraph using NodeJs

[mo...@fastfox.com]

Hi,

I am new to Janusgraph and want to try how I can interact with it using Node Js. Do I need to configure my gremlin server to allow remote connections? I am not sure how exactly that is to be done. Please help.

I get the following error when I try to run my nodejs code

const gremlin = require('gremlin');
const Graph = gremlin.structure.Graph;
const DriverRemoteConnection = gremlin.driver.DriverRemoteConnection;
const graph = new Graph();
const g = graph.traversal().withRemote(new DriverRemoteConnection('ws://localhost:8182/gremlin'));
g.V().has('lead', 'leadLeadId', '30087713').values('leadLeadId').toList().then(function(res){console.log(res)},function(err){console.log('Hi');console.log(err)});
Promise {

     _maxListeners: undefined,

Checked my gremlin-server log, there was a silly mistake in my configuration file due to which gremlin server was not getting started properly. Fixed it :)

How did you fix it?
