Neo4j-driver: Cannot read property 'driver' of undefined

Question

I pretty much copied the example and adjusted the database query. I dont understand why the driver is not recognized?

Version: Node: v11.13.0 neo4j-driver: "^1.7.5"

I get the Error:

var driver = neo4j.v1.driver(
                      ^

TypeError: Cannot read property 'driver' of undefined

My Code:

var neo4j = require('neo4j-driver').v1;


var driver = neo4j.v1.driver(
    'bolt://localhost:7687',
    neo4j.auth.basic('neo4j', 'Neo4j')
  )
  var session = driver.session()

session
  .run('MATCH (n:Person) return n', {
    //nameParam: 'Alice'
  })
  .subscribe({
    onNext: function(record) {
      console.log(record.get('n'))
    },
    onCompleted: function() {
      session.close()
    },
    onError: function(error) {
      console.log(error)
    }
  })

Try with `var driver = neo4j.driver(` instead of `var driver = neo4j.v1.driver(` — Fraction, Jun 25 '19 at 14:01

You probably meant to do this:

var neo4j = require('neo4j-driver').v1;

var driver = neo4j.driver(
...

Or, if for some reason you want to be able to explicitly specify the library version every time you use it, do this:

var neo4j = require('neo4j-driver');

var driver = neo4j.v1.driver(
...

their docs seem screwed up, I had the exact same problem. remove the v1 and it works. not sure if this defaults to a different version of the driver or something...

let config = require("./config")[env]

const uri = 'bolt://localhost:7687'
const neo4j = require('neo4j-driver');
const driver = neo4j.driver(uri, neo4j.auth.basic(config.username, config.password));

FWIW the way they define a config file is also broken. the node onboarding is pretty much a turn-off.
