If you’re new to React, you can read more about it on the React website. You can also get started with React Native for iOS, which was released at F8 2015 on the React Native website. It started with React We introduced React to the world two years ago, and since then it’s seen impressive growth, both inside and outside of Facebook. Today, even though no one is forced to use it, new web projects at Facebook are commonly built using React in one form or another, and it’s being broadly adopted across the industry. Engineers are choosing to use React every day because it enables them to spend more time focusing on their products and less time fighting with their framework. It wasn’t until we’d been building with React for a while, though, that we started to understand what makes it so powerful. React forces us to break our applications down into discrete components, each representing a single view. These components make it easier to iterate on our products, since we don’t need to keep the entire system in our head in order to make changes to one part of it. More important, though, React wraps the DOM’s mutative, imperative API with a declarative one, which raises the level of abstraction and simplifies the programming model. What we’ve found is that when we build with React, our code is a lot more predictable. This predictability makes it so we can iterate more quickly with confidence, and our applications are a lot more reliable as a result. Additionally, it’s not only easier to scale our applications when they’re built...
According to Michael Feathers, “Any code that has no tests is a legacy code.” So as a developer it is your duty to avoid creating legacy code by using test-driven development (TDD). There are many tools available for unit testing in ReactJS but we will be going through Enzyme and Jest. What is Test Driven Development (TDD)? Test Driven Development (TDD) is a programming practice which enables developers to write code only if an automated test has failed, thereby avoiding duplication of the code. The primary aim of TDD is to write code which is clear and bug-free. As a developer, you need to write tests for every small functionality of the application. It is a cyclic process and each cycle starts by writing a unit test. Test Driven Development can easily be compiled in four easy steps: Importance of Test-Driven Development (TDD) Using TDD provides the following benefits: Why Should You Use Test-Driven Development (TDD) for ReactJS? If you have worked with ReactJS, then you probably know that code grows really fast in ReactJS. The code gets filled up with a lot of complex conditions due to service calls and change of state. Every component of your React application that lacks unit tests becomes a legacy code which is very difficult to maintain. Although we can add unit tests after we create the production code, it will be very risky as some scenarios can get overlooked which will cause the issue at the production stage. Setting Up The Environment for Test-Driven Development (TDD) The most important thing to do first is to set up the environment for writing...
Big corporations trying to improve the user experience by making everything around simplify, increasing performance and connections with “IoT’s”. Today with the Android operating system installed on the most robust smartphones, we have their strengths and weaknesses. A Linux system, have their limitations and permissions. The user that makes the “Root” on the mobile device, will have full access to the system from view, edit and delete files and folders from the Android system and even install tools of various features. In this article, I will introduce to you how easy it is to have a smartphone with pentest tools and performing network scan, wireless scan, sniffer, Vulnerability Scanner and others. Preparing Android Smartphone for Penetration Testing Let us start preparing your smartphone to perform the invasion test. By Google Play itself, we have two apps (paid and free) to have the Android system bash terminal. Once the application installs, we will have to do the “Root” mode to have full access to the Android system. Therefore, we can install the pentest and monitoring tools. Apt-get is a powerful package management system that is used to work with Ubuntu’s APT (Advanced Packaging Tool) library to perform the installation of new software packages, removing existing software packages, upgrading of existing software packages. Inserting the Kali Linux repository link and updating the list First, we will use Linux repositories distributions for pentest, in this example, I am using the Kali Linux distro. Once we do the “apt-get update” command, we will have reliable fonts tools. Apt-get is a powerful package management system that is used to work with Ubuntu’s APT (Advanced...
When you are trying to look for a job or winning the heart of a client, the first thing that they would require from you is a copy of your resume. A resume is simply a document that showcases your skills and abilities. Usually, it is composed of only a couple of pages. In the past, hard copies of resumes were handed out and submitted to companies and employers. But in this modern day and age where everything is already running online, it is practical to have an online resume. There are two ways on how you can go about this. One is by using a dedicated resume builder, and another is by using a website builder. Regardless of which approach you choose to take, below are some of the key steps that you should follow. Step 1- Choose a builder In creating an online resume, the first thing that you need to do is to choose a dedicated resume builder or a website builder. If you opt for the former, you can instantly proceed to the next step after choosing the builder. However, if you opt for the latter, you need to also sign up for a plan and choose a domain name, before you get to choose a template. Step 2- Select a template Take time in choosing the perfect template for your online resume. While most templates feature various types of graphics and color themes, make sure to pick one that best reflects your personality and your profession. Explore some resume examples that you may find online. Once you have an idea of what looks good...
We have heard from many people that there is so much work happening with React Native, it can be tough to keep track of what’s going on. To help communicate what work is in progress, we are now publishing a roadmap for React Native. At a high level, this work can be broken down into three priorities: If you have suggestions for features that you think would be valuable on the roadmap, check out Canny, where you can suggest new features and discuss existing proposals. What’s new in React Native Version 0.37 of React Native, released today, introduces a new core component to make it really easy to add a touchable Button to any app. We’re also introducing support for the new Yarn package manager, which should speed up the whole process of updating your app’s dependencies. Introducing Button Today we’re introducing a basic <Button /> component that looks great on every platform. This addresses one of the most common pieces of feedback we get: React Native is one of the only mobile development toolkits without a button ready to use out of the box. Experienced React Native developers know how to make a button: use TouchableOpacity for the default look on iOS, TouchableNativeFeedback for the ripple effect on Android, then apply a few styles. Custom buttons aren’t particularly hard to build or install, but we aim to make React Native radically easy to learn. With the addition of a basic button into core, newcomers will be able to develop something awesome in their first day, rather than spending that time formatting a Button and learning about Touchable nuances....
