Trakya University Summit of IT and Innovation ’17

We were guest of Trakya University Computer and Innovation Club with Anıl Reis and Dilek Coşkun from Hepsiburada team on April 26, 2017. We were welcomed very warmly by the teachers and students when we had a long journey with nature. Murat Topaloğlu, the head of the department, mentioned about their curriculum in a place with a very nice view in the sponsorship of Coffee Table. Although I thought that their curriculum is so hard for undergraduate students, when I find the opportunity to chat with students, it is clear that the students are prepared nicely for the real life.

We gave Hepsiburada gift voucher to 5 students who answers our questions correctly during our presentation. We gave information about our working environment, the technologies and methodologies we use, and tried to answer questions that comes from students. After the presentation, we had the opportunity to visit the stands of some graduation projects. As an old Microsoft Student Partner Leader I found the opportunity to meet Derya Kendirci who is MSP of Trakya University. I wish good luck to her and her team in Microsoft Imagine Cup competition.

I would like to thank Murat Topaloglu, Duygu Solak, Egement Tekkanat, Furkan Akbaş and all the students who organized this event.

Node.js Hello World Application

After connecting your Windows server click "Node.js command prompt" under Node.js folder in Start menu. If you didn't install Node.js, you can install it by reading How to Install Node.js on Windows Server? post and then you can run "Node.js command prompt".

In "Node.js command prompt" screen, you can create your first application with the following commands. So what are the meanings of these commands?

Node.js Hello World

For those who do not know how to use command prompt, I want to explain 2 commands I use on the screen, regardless of the Node.js command prompt.

cd: change directory

mkdir: make directory

"cd C:\" command will change your current directory to main directory of C driver. "mkdir nodejs" command will create a new folder inside current folder.

Once you have created the C:\nodejs\helloworld directory and go to this directory, you can run the npm package builder to create a new Node.js application using the command "npm init". Package builder will ask you some informations respectively name, version, description, entry point, test command, git repository, keywords, author and license. You can create your application with default values (values inside paranthesis) with pressing enter key. I just change description and author fields. Once you have completed the information, you can create your application by checking the preview of your package.json file and pressing the enter key.

"echo console.log("hello world"); > index.js" command will create a file named index.js inside your current directory and writes "console.log("hello world");" into index.js file. The index.js value in this command must be the same as the entry point value. Finally, when you run your application with the "node index" command, you will see "hello world" text which you print it on the screen with "console.log" code line.

Congratulations, you have run your first application after installing Node.js in your Windows server on AWS.

How to Install Node.js on Windows Server?

We will make some changes in "Configure Security Group" step. To provide RDP, HTTP and HTTPS access to our server, we need to add these rules (RDP attached by default) first. In addition, you can add 8080 and 3000 ports to use for development. If you want to access your server from anywhere, you need to select "Anywhere" as "Source" property. If you want to restrict access, you can enter IP address by CIDR (Classless Inter-Domain Routing) notation after selecting "Custom" or "My IP". After you have done your settings, click "Review and Launch" button.
