Neo4j NodeJS code doesn't display the entire nodes data - node.js

Question

I have integrated Neo4j in my NodeJS (backend) and Angular6 (front-end) application. My query runs and i get the data of nodes and connected node network in my Neo4j Browser. However, i want that entire data of nodes being displayed through a particular query on my console (i.e. in NodeJS -> back-end and angular ->front-end). This is not happening . I get only the first node data. Please help me retrieve the entire displayed nodal data in NodeJS .
NodeJS code
neo4j-controller.js
// Require Neo4j
var neo4j = require('neo4j-driver').v1;
var path = require('path');
var logger = require('morgan');
var bodyParser = require('body-parser');
var express = require('express');
var router = express.Router();
var app = express();
const driver = new neo4j.driver("bolt://localhost:11001", neo4j.auth.basic("neo4j", "ib1"));
const cypher = 'MATCH (n) RETURN count(n) as count';
app.set('views', path.join(__dirname, 'views'));
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(express.static(path.join(__dirname, 'public')));
var session = driver.session();
var request = require('request');
router.post('/', seekParameter);
module.exports = router;
//working code below
// ------------------------------- Original Code ----------------------------------------
function seekParameter(req, res) {
console.log("INSIDE NODE JS CONTROLLER OF seekParameter");
console.log("BODY IS ", req.body);
session
.run(`MATCH p=()-[r:Parameter]->() RETURN p`)
.then(function (result){
result.records.forEach(function(record){
console.log("record = ", record);
console.log("result = ", result)
console.log("1] record._fields[0].properties=",record._fields[0].properties);
res.send(record);
});
})
.catch(function(err){
console.log("inside catch = " + err);
})
session.close();
}
output

Answer 1

Thanks. I resolved the issue.
The place and parameter i was passing in response was incorrect.
Correct code -
session
.run(` MATCH p=()-[r:Parameter]->() RETURN p ;`)
.then(function (result){
result.records.forEach(function(record){
console.log("record = ", record);
console.log("result = ", result)
console.log("1] record._fields[0].properties = ",record._fields[0].end.properties);
// res.send(record);
});
res.send(result);
})
.catch(function(err){
console.log("inside catch = " + err);
})
session.close();
}
