Setting up the Environment with Node.js

Hello! I hope you had a good day and an awesome week. 😊

As I promised on the previous post, in this one we’ll do some coding using Node.js. But before we jump into coding, we need to set up a proper environment.

Setting up the Environment

Before working with Node.js, it should be installed to your machine. So, to install, you can follow the link given below,

https://nodejs.org/en/download/

There, select the setup according to the operating system of your machine. When installing go with the default options. After the installation, open command prompt and type ‘node --version’ as below,



If the version is shown, Node.js is successfully installed to your machine. If not, it should be reinstalled.

Let’s Code

Let’s start small. First, we’ll see how to print something in the command prompt. A JavaScript file (a file with .js extension) should be created. Let’s call it ‘Hello.js’. This can be done using a simple text editor or using and IDE (Integrated Development Environment) which supports JavaScript.  Inside the file write the following.


Here I have used ‘use strict’, which is using the strict notation. Strict notation is the restricted mode in JavaScript. It helps to write secure JavaScript. It makes bad practices in JavaScript into errors and will keep the developer away from using syntax which will get invalid with upcoming JavaScript versions.

To run this, the command prompt should be opened in the working directory (the directory which you are currently at or where the previously created file is stored). In the command prompt type ‘node <name of the file>’, in this case, the name of the file is ‘Hello.js’, in order to run the file.



Node.js supports basically everything JavaScript supports.

So now you got a basic idea how to code, I suggest you just play around with Node.js. In the next post, we’ll go into more deeper stuff.

I wish you all an amazing week ahead! Adios ðŸ˜Š

Double Submit Cookies Pattern - Node.js

Hello! I hope you had a good day and an awesome week. 😊 In this post, we are going to talk about how to prevent Cross-site Request Forgery (CSRF) using Double Submit Cookies Pattern and its Node.js implementation. If you are unaware of CSRF, I recommend you to read my previous post here as it is crucial to understand Double Submit Cookies Pattern. Prerequisites are the knowledge about cookies, CSRF and Synchronizer Token Pattern. As discussed earlier, there are some drawbacks of Synchronized Token Pattern, namely, The requirement of excessive storage space in the server due to the fact that all the CSRF tokens are stored. Useless if the server supports cross-domain AJAX requests. To overcome the aforementioned reasons and to prevent CSRF, Double Submit Cookies Pattern can be used .

Hello! I hope you had a good day and an awesome week. 😊 With the advancement of technology in information and communication sectors, millennials are electronics-filled, increasingly online and socially networked, which is exactly why everything can be done once you are connected to the internet. Doing online transactions have become so much easy making it is just a button click but, can we guarantee the safety of these transactions? Cross-site Request Forgery (CSRF) is a type of attack which targets such online transactions. You’ll need to have the knowledge of cookies as a prerequisite to fully understand CSRF. What is Cross-site Request Forgery? Cross-site Request Forgery (CSRF) is a malicious exploit of a website where unauthorized commands are sent from a user the website trusts, without this particular user’s knowledge. This is a vulnerability found in websites. Let’s see the below example to understand CSRF. Cross-site Request Frogery When Harry ...
