connecting Neo4j to nodejs error

I am trying to set up neo4j databace to use with javescript code. When I run my code, I keep getting this

PS C:\Users\futur\Documents\Coding\Neo4j> node app.js body-parser deprecated undefined extended: provide extended option app.js:21:20 Server has started GET / 304 37.114 ms - - { Neo4jError: getaddrinfo ENOTFOUND locthost locthost:7687

code: 'ServiceUnavailable', name: 'Neo4jError' }

Here is what my code looks like

var express         = require("express");
var path            = require("path");
var logger          = require("morgan");
// var cookieParser = require("cookie-parser");
var bodyParser      = require("body-parser");
var neo4j           = require("neo4j-driver").v1;

var app             = express();


// 
// <script src="lib/browser/neo4j-web.min.js"></script>


//view engine setup
app.set("views", path.join(__dirname, "views"));
app.set("view engine", "ejs");

app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extened: false}));
// app.use(cookieParser());
app.use(express.static(path.join(__dirname, "public")));

var driver = neo4j.driver("bolt://locthost", neo4j.auth.basic("neo4j", "test"));
var session = driver.session();

//home route
app.get('/', function(req, res){
    session 
        .run("MATCH (n) RETURN n")
        .then(function(result){
            result.records.forEach(function(records){
                console.log(records._fields[0]);
            });
        })
        .catch(function(error){
            console.log(error);
        });
    res.render("index");
});


app.listen(3000);
console.log('Server has started');

module.export = app;

What do I need to do?

You may have a typo in your bolt URI.

If your code is running on the same machine as the neo4j server, try changing locthost to localhost.
