AngularJS NodeJS OracleDB application - node.js

Question

I want to get the data from oraclde db using nodejs and disply it over angularjs based ui. PFB my code for service.js :
var async = require('async');
var oracledb = require('oracledb');
var dbConfig = require('../utility/dbconfig.js');
var response = require('../utility/response.js');
var bodyParser = require('body-parser');
var express = require('express');
var router = express.Router();
router.use(bodyParser.json());
var dbdata='';
var app = express();
var oracledb = require('oracledb');
var dbConfig = require('../utility/dbconfig.js');
var doconnect = function(cb) {
oracledb.getConnection(
{
user : dbConfig.user,
password : dbConfig.password,
connectString : dbConfig.connectString
},
cb);
console.log('Connection was successful!');
};
var dorelease = function(conn) {
conn.close(function (err) {
if (err)
console.error(err.message);
});
console.log('Connection closed successfully!');
};
// Optional Object Output Format
var doquery_object = function (conn, cb) {
conn.execute(
"SELECT d.dc_name,c.cobrand_name,c.cobrand_id,c.IS_CACHERUN_DISABLED,c.is_channel,c.environment,c.COBRAND_STATUS_ID,c.deployment_mode,c.db_name,c.gatherer_group FROM cobrand_master c,dc_master d where d.dc_id = c.dc_id ORDER BY c.display_priority",
{},
{ outFormat: oracledb.OBJECT },
function(err, result)
{
if (err) {
return cb(err, conn);
} else {
console.log("----- cobrand_master details (OBJECT output format) --------");
console.log(result.rows);
return cb(null, conn);
}
});
};
async.waterfall(
[
doconnect,
doquery_object
],
function (err, conn) {
if (err) { console.error("In waterfall error cb: ==>", err, "<=="); }
if (conn)
dorelease(conn);
});
When I am doing npm start in command prompt, I am getting the data in JSON format.I want to save the output and send it over angular js UI. Since I am new to this, can anyone please help me with simple steps to do it with an example.
