在js中使用neo4j驱动程序

Question

I am pretty new to js and making web applications, but i have helped to build a web app that uses ne04j. I am trying to use the neo4j driver now with BOLT to access the community edition.

I am trying to use url = 'bolt://localhost:7474'

But i cannot get it to work.

I was wondering if this is because I need to somehow link the neo4j driver to the js script and if anyone could let me know how to do this.

var url_ = 'bolt://localhost:7687' 
var pword = 'neo4j2' 
sigma.neo4j.getLabels(
            { url: url_, user: 'neo4j', password: pword },
            function (labels) {
                console.log(labels)
                NodeLabels = labels;
                console.log("NodeLabels: " + NodeLabels);
            }
    ); 

Thank you!

FYI, 7474 is the http port, not the bolt one. So you need to replace bolt://localhost:7474 by bolt://localhost:7687 or by http://localhost:7474 .

The Sigma plugin for Neo4j only use the HTTP endpoint of Neo4j :

var url_ = 'http://localhost:7474' 
var pword = 'neo4j2' 
sigma.neo4j.getLabels(
  { url: url_, user: 'neo4j', password: pword },
  function (labels) {
    console.log(labels)
    NodeLabels = labels;
    console.log("NodeLabels: " + NodeLabels);
  }
);
