Inspect JSON Easily with BrijPad 2.0 (New Features)

For a web developer, it is common to view & analyze the JSON returned by an API to the browser and generally, Chrome Developer tools is used for this. You can click on Network tab, select the XHR item and can get JSON in Response and Preview tabs in Chrome developer tools. Fortunately, there are quite a few free online JSON viewers that you can use. Now, BrijPad 2.0 also allows you to inspect and analyze JSON quickly. You can paste the JSON code and visualize the data. I saw many online tools but didn’t get any tool which filters JSON by selecting field in TreeView (It is very helpful in case of large JSON) so I decided to implement it and added it in BrijPad 2.0.

WordPress: Customize Title in RSS Feed and Get it from Excerpt

Recently, I introduced #TechBrijTips, A micro-blogging section on this website which has content like twitter posts. It is different from regular blog posts as it doesn’t have any specific title. So I had a question what to display in the RSS feed of WordPress. It doesn’t look good to me to display first few words of the main content. I decided to display title from Excerpt. In this post, we will see how to implement it.

Introducing #TechBrijTips for Micro-blogging

The beauty of Microblogging is that you can express yourself in lesser words and can share frequent and brief information on web. As its name suggests, a microblog post is based on micro (i.e. short) post. It requires less time and effort. Ideas, information and thoughts can be shared instantly once they come into your mind. So, I decided to setup Microblogging platform on TechBrij and added #TechBrijTips section to share knowledge, tips, the latest news and useful resources related to web development. As it needs less time to spend on researching a specific topic, being a part time blogger, it will be helpful to increase community and reader engagements.

RabbitVCS: A TortoiseGit for Ubuntu

I am fan of TortoiseGit on Windows as Git client. It displays icons on files and folders of the repository in file explorer which is easy to know the status. You can perform different repository operations in the explorer itself without open a standalone app for Git. Nowadays, I am using Ubuntu so much. So, I need the same in Ubuntu 18.
On googling, I found RabbitVCS. It is a graphical front-end for version control systems available on Linux and it integrates into file managers to provide file context menu access to version control repositories like TortoiseGit.

Setup Dev Environment with a Local Blockchain and Deploy Smart Contract [Full Stack Ethereum Dapp Part-2]

In Part-1, we made Hello World contract in Remix. As we have to write code in the files and manage in repository for development perspective so in this blog post, we will setup our development environment, a private Ethereum blockchain on local machine and deploy our smart contract on the blockchain. I am using Ubuntu 18 for writing this post. But can be setup on Windows and MAC machines.

Hello World Smart Contract In Solidity [Full Stack Ethereum Dapp Part-1]

In this tutorial series, we are going to build a simple Hello World Dapp (decentralized application) on Ethereum with Solidity, Truffle & Web3 tech stack. After this, we will deploy it to test network (Infura and Heroku). This dapp will simply store and retrieve user input text on Ethereum.

In part one, we’ll write a smart contract in Solidity using Remix. Let’s build a simple ‘Hello World’ application (The best way to learn new technologies). It is assumed you know the basics of Blockchain and its terminology. Here is quick intro of some terms:

JavaScript: Select Date Time with Timezone

This tutorial explains how to implement to get a JavaScript date object from user selected date time & timezone and the date object can be sent server side to save or for further processing. HTML5 provides input type datetime-local allows user to enter both a date and a time and the user’s local time zone is used. For simplicity, Let’s enhance this to allow user to select any timezone.

JavaScript Async/Await: Serial, Parallel and Complex Flow

If you have experience on ASP.NET MVC then probably you are familiar with async/await keywords in C#. The same thing is now in JavaScript. Before that, Callbacks and Promises are used for asynchronous code. Async/await is built on top of promises and non blocking. The power of Async/await provides asynchronous code look like synchronous code. In this article, we will go through serial/chain and parallel flow and implement a complex flow using Async/Await.

Visual Studio Code: Debugging ES6 Mocha tests with Babel

In my post, I explained how to test server side REST APIs in Node.js using Mocha, Sinon and Chai. I used ES6 test methods for this and Babel is used to execute it. As test methods are executed at development end, so NO need to transpile ES6 to ES5 first and then debug the converted files. You can directly debug ES6 code with Babel.

Node.js: Traversing A Directory Recursively with Limited Depth

In this post, we will implement to get all files recursively in a directory using Node.js. Also, will restrict it to traverse directory with limited recursively depth.

Before we get started, consider the following directory structure(For simplicity, the name is according to their depth level i.e. folder 1, sub folder 1.1, sub sub folder 1.1.1…etc):

1 > 1.1 > 1.1.1> >
2 > 2.1 > 2.1.1
  > 2.2

Each directory has txt file with same directory name(means 1.1 will have 1.1.txt file).
