Basic Usage

Create a dse.Client instance and use it to obtain traversal sources:

const dse = require('dse-driver');
const dseGraph = require('dse-graph');
 
const client = new dse.Client({
  contactPoints: ['host1', 'host2'],
  graphOptions:  { name: 'my_graph' }
});
 
// Obtain a traversal source, used to create traversals
const g = dseGraph.traversalSource(client);
 
// Use the traversal source to create traversals
// ie: Print john's friends names
g.V().has('name','john').out('friends').values('name').toList()
  .then(names => names.forEach(console.log));

You should reuse the Client instance across your application.
