Hide Your API Keys With an API Proxy Server
Thu, 11 Aug 2022

In this article/tutorial, we are going to create an API Proxy Server using NodeJS, and the main reason behind this is to show you how to hide public API keys and not expose them in the public like I was doing in the past. All of us have created an application once just to get to know a new library or a framework, and the best way to achieve this is to use an open API (like TMDB).

Most of these open APIs require adding the API key in the request URL or in the headers before making the request. Either way, the API key can be stolen and used by people that are not actually own this key. As a result, you may end up with a suspended account, or your application not work as you've expected it to.

Why Should You Choose ReactJS for Your Next Project?
Thu, 11 Aug 2022

We have to think too much before it’s ready to deploy — from hiring a developer to wireframing to finding a target audience to platform. With ever-changing technologies, innovation in the development framework makes it possible to decrease development time. The less time you spend on developing, the faster you deploy the app in the market. 

However, the time of development depends on the technology framework you choose. Faster development is one of the many reasons why cross-platform applications are preferred over native apps. However, many big companies and brands are using React Native nowadays. It’s one of the leading mobile app development frameworks that is used and trusted by Facebook, Skype, Instagram, Airbnb, and many more.

TURN Time Into Value
Wed, 10 Aug 2022

Web2 software engineers have benefitted from design standards, mature programming languages, and vulnerability tools to minimize the risks of an attack. Failure to do so can result in a situation similar to my “Equifax Attack: Only a Matter of Time” publication back in 2017.

Those working in Web3 projects find themselves at an exciting stage. Initiatives like bounties and Decentralized Autonomous Organizations (DAOs) drive new opportunities for these pioneers to explore. Unfortunately, the Web3 landscape is not as mature or defined as earlier phases in the web frontier. Compounding the situation is the risk those challenges impose in a decentralized environment — where exploitation can result in losing a large volume of assets, as well as the time it takes to secure an auditing service for smart contract code and the duration of the audit itself

Event Loop in JavaScript
Mon, 08 Aug 2022

JavaScript is an integral part of any website. It is responsible for all its logic and data manipulation. It is the most popular language used to build websites. This extremely versatile language can be used for virtually anything. This does not necessarily mean that it will best suit all applications, but it will be able to compete with the leading languages in many respects. It is this versatility that makes it worth finding out about its underlying mechanisms and thus its strengths and drawbacks. 

JavaScript is single-threaded, which means that only one action can be performed at a time. JavaScript uses a single thread to handle all requests, but when creating contexts, it uses other threads to handle input/output, so it does not get stuck. JavaScript can communicate between threads, using external interfaces that are able to create such other threads, it can communicate. For example, if you create a web page, it runs on a single thread but is able to communicate with other threads that work for some specific purpose. This is the case when using a camera. The camera is such a separate service for the browser and is a separate thread. And this is not happening on our thread but on an external one. 

Diving Deep into Smart Contracts
Fri, 05 Aug 2022

The “Moving From Full-Stack Developer To Web3 Pioneer” publication provided a high-level overview to give full-stack developers a glimpse into the world of Web3 development. If you haven’t had a chance to review that article, consider taking a look, since it provides a good introduction into Web3 there as well.

The end result of my original article demonstrated how a homeowners association (HOA) could use Web3 technology to host their election ballot. The problem with the original design is that the underlying smart contract only allowed for a single yes or no answer. This was by design to keep the smart contract simple, while introducing other concepts required to create an HOA ballot using Web3 technologies.

Onboarding New Users With Coinbase Wallet
Thu, 04 Aug 2022

Web3 represents an exciting chapter in the development of the internet. The primitives that the blockchain provides will lead to an infinite number of applications and use cases. We’ve seen the explosion of ICOs, DeFi, NFTs, and peer-to-peer payment systems. However, we still have a long way to go before reaching the mass adoption of this new technology. User experience is one area where things still lack.

As Web3 developers, how are we supposed to onboard the next wave of users when the average person doesn’t understand concepts such as non-custodial crypto wallets or signed transactions? This article will explore the issue, and offer a solution to help create a better user experience. We’ll look at a real-world example of how we can use the Coinbase Wallet SDK to create a seamless onboarding experience for new users.

The Impacts of Blockchain on the Software Development Industry
Wed, 03 Aug 2022

Blockchain is the most reliable technology in recent times that caters to our responsibility of complying with the IT compliance obligations. Blockchain technology not only secures the data and transactions but also simplifies the processes involved in developing software products. 

This possibility of any intricate system becoming a part of a larger, more trustworthy network of transactions makes it a promising technology for companies to adopt.

Trending Programming Language to Learn
Tue, 02 Aug 2022

It wasn't that long ago when computer programming was an almost unknown and secluded field. Back then, there used to be only a few people who had the advanced coding skill set to be considered computer programmers. 

But today, information technology is evolving at a faster pace than ever before. In parallel with the rapid development of the IT sector, there is a rapid growth in the market demand for specialists.

The Essential Web3 Tools and Technologies Developers Must Know
Tue, 02 Aug 2022

Web3 is the next iteration of the web. As opposed to Web1, which consisted of static web pages, and Web2, which brought us web apps and the web as a platform, Web3 consists of decentralized networks built on blockchains.

There is a high demand for Web3 developers, as relatively few current developers are experts in this field. So if you’re an established Web2 engineer wanting to break into Web3, where would you start? What are the fundamental concepts to know, and what tools and technologies would you need to learn?

CockroachDB and Deno: Combining Two “Quick to Start” Technologies
Tue, 02 Aug 2022

This tutorial will walk through building a simple application using Deno, backed by CockroachDB (CRDB) Serverless. Deno (pronounced dee-no) is a “modern runtime environment for JavaScript and TypeScript”, while CockroachDB Serverless offers a free startup that scales with your app. Both technologies claim quick startup times for developers, so I’d like to test them out together and see how quickly we can get a full end-to-end application running.

Difficulty: Beginner (assumes no prior experience with CockroachDB or Deno)
