This list of React native libraries is not curated randomly from the Internet. These are the libraries that I use personally in my apps. There may be alternatives for these libraries but I chose these after a good amount of research and trying them out in my apps. I’m also giving some live practical examples of how I use these libraries. So here’s the list of top React Native libraries This library is really good for quickly adding simple animations and transitions to your React Native app. This library can be used in 2 ways – Declarative and Imperative. Declarative usage – Simply mention the name of one of the pre-built animations and that animation will be applied as soon as that element loads. Ex: Heading should slide in from left when a page is opened. Imperative usage – If you want to play animation manually then this method works great. Ex: wobble a heart icon when someone likes a post. You can also define your own animations! For complex animations, I prefer to use React Native’s Animated API from scratch. Practical example Check the gif below. Profile page with simple transitions – Profile Image has a zoom in animation, Profile details slide-in left with a delay. Finally, like icon has a small wobble animation when someone likes a post. This library has very good support for Local push notifications. It has features like schedule notification, repeat notification based on day, week, time etc which are not available in other libraries. If your app has an offline-first approach and needs push notifications then this library is the way to...
Working on any software product is a complex process requiring expertise, a budget, competent management, and taking into account many various factors. Indeed, starting a project is one thing, and bringing it to successful release is quite another. The industry is rapidly developing, the competition in the App Store and Google Play is enormous, and only a few manage to at least bring the product to a successful release, leave alone consolidating their position in the market. To make the success likelier, it is important to know the main reasons why mobile app development projects fail and how to avoid failure. I will tell you about this in this article from the perspective of our perennial development experience. No Market Research It may seem you have found a bright idea that will earn you millions. You may also decide to take the easy route and create a clone of an existing popular app, for example, Tik Tok or Instagram. In all these cases, you risk spending time simply developing an unnecessary product unwanted on the market. That is why you cannot skip such an important stage as market research and competitive environment analysis. If the analysis results show at once that the project has no prospects in its current form, you will be able to save plenty of money and time. Moreover, you will manage to see what you have to change to make your app highly-demanded in the future. There are 5 simple ways to validate your mobile app idea: Want to start a project?

Data breach at an international student insurer, avoid stalkerware and the latest business email scam. Welcome to Cyber Security Today. It’s Wednesday May 19th. I’m Howard Solomon, contributing reporter on cybersecurity for ITWorldCanada.com. A Canadian-based insurance firm called guard.me has begun notifying policyholders of a data breach. The Markham, Ont., company specializes in covering international students not protected by government insurance. According to the Bleeping Computer news site, policyholders are being told the company spotted suspicious activity on its website on May 12th. Data accessed includes dates of birth and genders. The email and physical mail addresses, as well as phone numbers of some policyholders, were also copied. The data breach notification also says the company is now adding two-factor authentication to protect logins. Does your organization allow employees to use the Internet Explorer browser? Do you as an individual use it? If so, better make sure the browser is patched. Bitdefender says an exploit kit used by a number of cyber attackers now includes ways of getting at two unpatched vulnerabilities in Explorer to deposit malware. Victims get hit just by going to an unsuspecting but infected website. By the way, one of those patches dates back to 2018, the other to 2019. Why they haven’t been installed yet by some people is baffling. Stalkerware is a category of mobile apps that allow someone to monitor other people. Another word for it is spyware. Jealous lovers might secretly install stalkerware on a partner’s smartphone. They might tell the victim it’s an app for their own protection. Some spyware is marketed as a child or employee monitor. They come...
Published Sep 30, 2018 • Updated Mar 7, 2020 Last year I wrote a post introducing clean architecture and attempted to explain how its layered approach and separation of concerns can help overcome some common software design pitfalls enabling us to create testable, loosely-coupled code that is easier to maintain and extend. In this post, we’ll revisit Clean Architecture in the context of a somewhat more real-world example by using its principles to design and build an ASP.NET Core based Web API. Understanding these principles is critical for this guide and I won’t be covering the basics from scratch so if you’re new to Clean Architecture I recommend you check out my previous post or Uncle Bob’s to get up to speed. This guide also assumes knowledge of other topics like MVC, dependency injection and testing so if you run into something you’re not familiar with please take a moment to familiarize yourself with any new concepts. Get notified on new posts Straight from me, no spam, no bullshit. Frequent, helpful, email-only content. A Story of Layers and Dependencies At its absolute core, Clean Architecture is really about organizing our code into layers with a very explicit rule governing how those layers may interact. The overriding rule that makes this architecture work is The Dependency Rule. This rule says that source code dependencies can only point inwards. Nothing in an inner circle can know anything at all about something in an outer circle. With that in mind, to get started; I’ve fleshed out a project structure that should represent each of the logical layers in the diagram. Let’s break...
The normal flow of visiting a website is that you load a page & if you want to see new information you have to either reload the page to update it, or click a link to visit a different page. This a synchronous flow. New data is only presented when a new page is requested from the server. But… What if you don’t want this page reload? What if you want to fetch data from the backend, at any time you want, so that you can update any part of the current page? This is where AJAX comes in. AJAX stands for Asynchronous Javascript & XML. It’s a technique that’s independent of your web framework, but Rails specifically has good support for it as you’ll learn in this article. Keep in mind that adding AJAX into your app makes it more complex. Direct AJAX Request AJAX has two parts, the request, which you make from the browser using Javascript, and the response, which you handle from your Ruby app. You can make an AJAX request with plain Javascript. But because that requires a lot of boilerplate code we usually do this through a Javascript library like jQuery. Here’s what a jQuery request looks like: However, since Rails 5.1 jQuery is not available by default (but you can add it back). Note: You’ll get an InvalidAuthenticityToken error when you do a jQuery POST request, this means that you need to submit the csrf-token from the current page as a security measure. Using Rails.ajax does this for you automatically. There is a solution! Rails includes its own AJAX function: Remember, this...
