How to make image slider in AngularJS from scratch

Hi, I hope you like angular and seeking to make an image slider, right? I will show you how to make image slider in AngularJS from scratch.
I was searching for a good slider in AngularJS that will be able to show my products with three images in a row or carousal but one image in the middle will be some bigger or some different style look. I did not find proper library that can meet my exact need. Finally, I decided to make the slider from scratch that will fulfill my requirements.

I will share with you the tricky ways in AngularJS that I followed to make the slider. You can also make your own slider if you can understand my tricky rules. That's actually very easy thing when you know JavaScript well and set necessary algorithm. I will make a slider that will display three image in a row and will pass by one image when click on next or previous and it will come the next images repeated after it  finishes the view. The slider will look like the following.

I have followed a basic project structure for angular slider project. Here is my folder and files structure.

Comparing Nodejs v6 Vs PHP7 Performance Benchmarking

I will show you a comparison of performance between Nodejs and PHP. This is my PC configuration.

I will compare
===================
The version of NodeJS:  v6.4.0
The version of PHP   : PHP 7.0.8


Nodejs Code:

app.js

var http = require('http');
var server = http.createServer(function (request, response) {
response.writeHead(200, {"Content-Type": "text/plain"});
response.end("Hello World\n");
});
server.listen(8000);

PHP code

index.php

<?php

echo "Hello world";

Running the server:
===============
I have used node built-in http server to run the nodejs code
node app.js 
 the node server is running on http://localhost:8000

And I have used php built-in server to run the php code

php -S localhost:8080

the php server is running on http://localhost:8080


Benchmarking:
==================
I did benchmark with siege, and ran them on the same machine. To install siege on Ubuntu, you can run sudo apt-get install siege . First, I have run this test on node server

siege -q -c 100 -b -t 60s http://localhost:8000/

and got this result for Node:

Transactions:              572363 hits
Availability:              100.00 %
Elapsed time:               59.29 secs
Data transferred:            6.55 MB
Response time:                0.01 secs
Transaction rate:         9653.62 trans/sec
Throughput:                0.11 MB/sec
Concurrency:               99.83
Successful transactions:      572363
Failed transactions:               0
Longest transaction:            0.04
Shortest transaction:            0.00

Afterwards, I have ran the same test on php  server  by the following command

siege -q -c 100 -b -t 60s http://localhost:8080

and got this result for PHP:

Transactions:              443534 hits
Availability:              100.00 %
Elapsed time:               59.49 secs
Data transferred:            4.65 MB
Response time:                0.01 secs
Transaction rate:         7455.61 trans/sec
Throughput:                0.08 MB/sec
Concurrency:               99.74
Successful transactions:      443534
Failed transactions:               0
Longest transaction:            0.08
Shortest transaction:            0.00

Finally, we can see that NodeJS is more faster than PHP.
