Angular 4 Node Mssql - sql-server

Question

I am a newbie when it comes to web development . I am currently working to get a real time web project up and running . I have a ms sql server 2014 working in my workplace and have installed node.js/ and used express generator to generate out an application . I have used mssql node module to connect and retrieve data from mssql server and it works.Although, Things that are confusing to me at this point:
how do i add angular 4 into the equation to help with the frontend development?i have already done npm install --save anular/cli but do not know where to start regarding creating input forms with drop downs whose values are to retrived from the DB .
my app.js:
var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var index = require('./routes/index');
var users = require('./routes/users');
var app = express();
// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
// uncomment after placing your favicon in /public
//app.use(favicon(path.join(__dirname, 'public', 'favicon.ico')));
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));
app.use('/', index);
app.use('/users', users);
// catch 404 and forward to error handler
app.use(function(req, res, next) {
var err = new Error('Not Found');
err.status = 404;
next(err);
});
// error handler
app.use(function(err, req, res, next) {
// set locals, only providing error in development
res.locals.message = err.message;
res.locals.error = req.app.get('env') === 'development' ? err : {};
// render the error page
res.status(err.status || 500);
res.render('error');
});
module.exports = app;
my index.js (i tried to create a connection with myssql and display a table in the index.html jade file)
var express = require('express');
var router = express.Router();
/* GET home page. */
router.get('/', function(req, res, next) {
GetData(function(recordset)
{
res.render('index', {projects: recordset })
});
});
function GetData(callback )
{
var sql = require ('mssql');
const config = {
user: 'sa',
password: 'password',
server: 'localhost\\SQLEXPRESS',
database: 'xxxxx',
options: {
encrypt: false // Use this if you're on Windows Azure
}
};
var connection = new sql.Connection(config, function(err)
{
var request = new sql.Request(connection);
request.query('select * from Project_Type' , function(err, recordset)
{
callback(recordset);
});
});
}
module.exports = router;
Some more questions:
Is this the right place to start a sql connection ? or should i put in in the app.js file
and other advice as to how to setup the environment and angular to properly speak with the db would be highly appreciated.
