Learning ReactJS Need of the Hour

Jason Rees — Mon, 06 Jan 2020 13:00:06 +0000

ReactJS is a declarative, efficient JavaScript framework used to build interactive user interfaces (UI) with greater ease and flexibility. React’s advantages exceed its disadvantages manifolds in making it a robust and adaptable programming library.

In a shorter span of time ReactJS has gained spotlight amongst developers and is emerging as the top choice for businesses and brands because of the innumerable benefits it offers. Top developers recommend learning ReactJS in 2020 to budding developers because of the many advantages in building highly engaging web applications and user interfaces in lesser time, where they create large scale apps with frequently changing data.

Apparently, ReactJS is strongly associated with successful brands like BBC, Instagram, Netflix, PayPal, and many such popular brands. According to a Similar tech survey, the United States of America is the leading country globally hiring react developers, as compared to other nations like Japan, China, Russia, UK, etc.

It provides many advantages in designing simple views for different states in an application and greater ease in updating and rendering the right components efficiently just when the data changes.

Lets check few of the many advantages of ReactJS:

Amazing front-end development experience
Suitable for both start-ups as well as established businesses
Better productivity
Better Code stability
SEO friendly environment
Ease of learning

Businesses are rapidly implementing this technology because of the simplicity it offers and the ability to learn in bare minimum time. Code reusability with hassle-free addition/modification of functionalities in the existing system meant allocating very less time and budget on the development and building larger teams in tandem.

React’s benefits of being robust, advanced, responsive,non-risky, user-friendly far exceed its disadvantages and developers and organizations understand React’s relevance in the market, so they are promoting its learning and deployment wholeheartedly.

React-Redux Hooks with Typescript in 2020

Jason Rees — Thu, 02 Jan 2020 08:44:59 +0000

This is going to be a continued version of our previous blog, React Hooks with Typescript, So if you are new to hooks, I would suggest looking into that article first, which talks about setting up the starter kit of react hooks with typescript and AntD for UI components.

If you know basic of react hooks, like useEffect or useState, you can even give it a skip.

Since React push using of functional components, a lot of libraries around react start publishing their own hooks, Redux being one of them, as almost most react project use redux these days.

The Redux hooks APIs provide an alternative to connect HOC and go away with mapStateToProps, and mapDispatchToProps, and I must say these hooks API provide a much cleaner way of doing that.

Now without going much in theory, lets deep dive into the coding part.

React Hooks with Typescript: Use State and Use Effect in 2020.

Jason Rees — Tue, 31 Dec 2019 11:56:10 +0000

Released in React v16.8.0, React Hooks address a number of issues with React, and perhaps most notably for TypeScript users, provide a first-class solution for reusing stateful logic, built with typing in mind. Due to this, a lot of the types for Hooks can be inferred, but in some cases explicit types must be set.

We are going to use typescript for this tutorial, so that our code remain 100% typesafe, and I must say if you are doing a big project, Typescript is a must feature one should go with, which helps to keep the code clean.

The above command will create a project with the name codersera-hooks-tutorial. Once it is done, go straight to the directory and either npm start or yarn start, will kickstart the project.

We will be using yarn throughout this tutorial to maintain consistency.

Let us now integrate antd ( a design library by the name of ant design), which we will be using to have some standard UI components. And, this does not have to do anything with hooks or react in general.

Integrating antd in react with hooks.

That’s all, we now have a complete typescript setup off react with antd design library integrated.

Using State with hooks in React (React.useState)

Let us see how the state is used with hooks. For this, we are going to create a simple form component, that will show the value in the input field upon submitting the form.

Software Engineer/ Manager Interview Questions

Jason Rees — Mon, 18 Nov 2019 12:37:20 +0000

Software development is a new stream in business management and most of the products are customized as per client’s requirements. In today’s ever-changing, rapidly evolving Information technology market, prime importance is given to management skills of the "Software manager" as the techniques and development experience of one product can be absolutely opposite or irrelevant to one another. In other words, we can say the findings of one product may not be useful to others at all and to survive the cut-throat competition in this ever-evolving software scenario, constant upgradations of skill-set, updating to the latest technology, modules are the only way out to survive.

Software project management is an art and discipline of planning and supervising software projects. Time, cost and quality are considered the basic parameters in Software management. Organizations have become very selective in hiring the best talent pool for Software management of their organizations in order to deliver quality products at a restrained budget, with profits, and on-time delivery. A Software engineering manager closely monitors the development process, and executes various plans, arranges necessary and adequate resources, maintains communication amongst all team members in order to address issues of cost, budget, resources, time, and quality and customer satisfaction.

A successful Software engineering manager is always tested on these three parameters of time, cost and quality delivered which get affected due to several internal and external factors. Software project management comprises of a number of activities, which contains planning of the project, deciding the scope of the software product, estimation of cost in various terms, scheduling of tasks and events, and resource management.

Here are a few key essential questions which needed to be asked to any Software manager before hiring:

What are your Project Estimation Techniques?
What are your most successful projects so far?
What were the cost estimations for your last project?
What is your Project Scheduling Techniques?
What are the IT policies/ laws to comply with new IT standards?
What is Risk Management?
What are your Communication/ Conflict management strategies?
What is the Scope Management?
What are the training programs for the employees?

There is no doubt that Google Chrome is one of the most popular and widely-used web browsers among other web browsers like Safari, Firefox, etc. As so many Plugins are available in the Chrome web store, you can customize your browser in many ways to help you work more efficiently.

We went through the Chrome Web Store and compiled the list of top 10 google chrome plugins on the basis of four criteria :- Productivity, Web development, Time-saving and Blocking distractions.

Top 10 Google Chrome Plugins You Must Try

“In computing, a plug-in is a software component that adds a specific feature to an existing computer program. When a program supports plug-ins, it enables customization. Web browsers have historically allowed executable as plug-ins, though they are now mostly deprecated. (These are a different type of software module than browser extensions.) Two plug-in examples are the Adobe Flash Player for playing videos and a Java virtual machine for running applets.“

How To Make React VR Apps

Jason Rees — Mon, 23 Sep 2019 13:19:10 +0000

VR web apps can be built with the React VR apps. WebVR is an experimental API enabling the creation and viewing of VR experiences in your browser. This new technology enables you to grant access to virtual reality regardless of the devices at hand.

The only thing you need to make a React VR app is a headset and a compatible browser. If you are just viewing a web VR application then you don’t need even for a headset. React VR is a great framework to build VR websites or apps on JavaScript. It utilizes the same design as React Native and lets you make virtual reality tours and under interfaces with the provided components.

Challenges Software Developers Face Today

Jason Rees — Fri, 20 Sep 2019 05:57:37 +0000

The Creative Minds behind the computer programmes are software developers. They develop complex softwares to perform the specific task in devices.

But it’s not that easy to develop software for any software developer, especially for beginners. Initially, they might face a lot of challenges while developing any software.

Software development is a dynamic industry today and building a high-quality product is the goal of every organization which creates challenges on every step for software developers. Thus they are struggling to be on top of new technologies for their profession.

Technical Challenge

Technical challenges are what you face normally while associating the core coding of software development. Some major challenges are:-

Not Understanding The Project:

Users may have their own opinion to build software but it creates difficulties for a developer as they barely get to interact with them directly.
The same problem occurs when you work on the unestablished project because every development project required a test and pre-production. Sometimes you get some complex project and it’s hard to cope up and work on each and every part of the project, single-handedly. In some cases, you might have to work on code written by another developer. This situation can cause problems for new developers.

Planning a project:

Planning a code is one of the important parts of software development. For building a good product you need proper planning. Because sometimes you might not get expected output after executing the code.

If you are a beginner so here are some tips to avoid such scenarios-

Always start with putting your ideas on paper rather than carrying them around in your head. It will help you to focus on what you are about to code.
Once you figure out the idea, start addressing the problems which your product will resolve.
As you get the problems, now think about the solutions for those problems.
Debugging:

When a software failed to execute properly. A developer debugs the software to identify and analyze the bug to resolve. It is considered as the most complex part because errors need to be resolved at all stages of debugging.

Usually, New programmers found these bugs ( App is crashing or some button is not working or not clickable ) from QA.
But some bugs are not easy to debug. This can lead to lost development time and endless frustration for new developers.

But bugs are common in programming, even best-written code can have them and they can be fixed.

Reproducing is a great idea to understand the errors and it will give you a good idea on how to resolve them. The tester who found the issue can help you to reproduce it.

Nuxt, Next, Nest! Confused?

Jason Rees — Tue, 17 Sep 2019 08:50:54 +0000

Programming is the method to innovate something new and amazing. Being a coder, it is important to be aware of every new upcoming technology. “Nuxt”, “Next”, “Nest” a little confusing, right? They might sound similar but their practical application is different from each other.

The coders who aren’t familiar with these frameworks might get confused in the beginning, these are the perplexed and complex words. I’m going to explain all concept of Nuxt, Next, and Nest so stay tuned with me, in this article you may explore the uses and the installation of these frameworks. Surely, this article will help you to know about these frameworks in depth.

Do you ever think why do we actually need a framework? What are the uses of framework?

A framework is a platform which provides a foundation on which software developers can create programs. It allows the coder to make robust applications.

Also, the framework provides diversified support for developing robust applications with pace and ease because it provides a standard way to build and deploy applications.
Before starting with these frameworks, let’s have a short briefing of CSR (client-side rendering) vs SSR (Server-side Rendering).

By these platforms, it is important to understand that Vue and React are client-side Rendered (CSR) framework, which makes the page interactable and viewable.

Ubuntu Vs Mac OS

Jason Rees — Thu, 12 Sep 2019 07:49:38 +0000

An operating system (OS) is system software that manages computer hardware, software resources, and provides common services for computer programs. (source: Wiki).
All major platforms (hardware and software) require an operating system. In general, OS is a software that allows users to run other application programmes in a computing device. Ubuntu and Mac are the second most common desktop OS after windows.

History Of Ubuntu

Linux has come with a lot of distros and its popular distribution is Ubuntu. Linux was already established in 2004, but it was not open source for every user. Hence Mark Shuttleworth decided to make a team of developers from the one of established project Debian and create an easy to use Linux desktop: Ubuntu. Ubuntu has free software available for all and funded through a portfolio of services provided by canonical.

Linux is a popular open-source operating system which is also referred to as Linux kernel. Linux is an open-source platform where user can download it and modify its source code. It is the most-used OS for desktop and server application. It provides all necessary components (tools, service and programmes) for a fully operating system.

They give special privilege to some highly qualified developers for being part of their free software foundation as Linux/GNU to build a better community. Many companies in the market make various Linux OS and core kernel with all components but Linux kernel is developed and maintained by Linux foundation.

Releases:

Ubuntu released on 20 October 2004 and it’s latest released version is Ubuntu 19.4 (18 April 2019).

Linux kernel was first released on September 17, 1991, by Linus Torvalds. It was originally developed for Intel x86 computers but later, ported to other platforms as well. Having dominancy in android OS smartphone, Linux has highly installed in the general-purpose operating system.

Linux is the foundation of many opearting systems like Android, Arch Linux, Debian Linux, Gentoo Linux, Ubuntu, Mandriva Linux, Pc, red hut Linux, Sabayon Linux, Slackware, Suse Linux.

History Of Mac OS

Mac OS is an operating system of Apple computer Mactonish series, (computers and workstations) having a graphical user interface which is only developed and maintained by Apple engineers themselves. Apple developed the whole system including Kernal, desktop environment and pre-installed software. Mac OS is the second major series of Mantonish operating system.
Apart from all specifications, it looks better than other systems as well.(personal preference)

The Essential Guide to NDAs (Non-Disclosure Agreement ) For Beginners With Template.

Jason Rees — Tue, 10 Sep 2019 13:47:58 +0000

Every company has its own planning and R&D (Reseach & development) to grow their business, as well as there, are many secrets of the companies which they are want to keep confidential from their public and competitors.

I have met many owners of large and small organizations and they all are very secretive with their coming new strategies. Business owners are always on their toes while keeping their next move confidential that’s why before launching a new product or expanding to a oversees market, they sign the NDA with all the people who are involved in the project.

If you guys aren’t familiar with NDA and its objectives? or why it is important for almost every company?

Here we’ll try to get doubts to surround NDA as well as you get the Essential guidelines for Dummies.

What is NDA?

It is a legal contract/ document that builds a confidential relationship between two or more parties, which use to protect proprietary or any secret information in business. An NDA (Non-Disclosure Agreement) use anytime to any potential investors, creditors, clients, as well as suppliers.

An NDA also is known as:

Confidential disclosure agreement (CDA)
Proprietary information agreement (PIA)
Secrecy agreement (SA)
Confidentiality agreement (CA)
For startups, why NDA is important?

Starting from the beginning, it is important to secure your marketing strategies from your competitors so that they don’t stale any sensitive information from you. There are many business partners, clients who sign an agreement with the company and NDA ensure the safety of your ideas.
