      image

      With the advancement in web technology, the entire globe is sliding towards the online tech sphere. The globe around us is going tech-centric day by day and thus the demand for front-end designers and developers also.

      Whatever, be the purpose, people just google things and get their desired result. This is all because of the increase in the evolution of web and mobile app development. While we all know that to be a Web developer, you need to have basic skills of HTML, CSS, and JavaScript, but, with time React.js emerged into the technology stack of the web development field and outdated JavaScript.

      A Report by JS reflects that 64.8% of the web developers prefer to use the React.JS framework and would love to use it again and again in the future. It has even beaten other categories of frameworks that are Vue.js with 28.8% votes and Angular with 23.9% votes. This is the reason why the demand for React.JS development companies is at an all-time high.

      With React, it becomes painless to build an interactive user interface. It efficiently updates and renders the right components when changes are made.

      Before you use React.js as web technology, let’s have a look at the practices that every React.js developer should follow to write better react codes for their application.

    • Most Popular JS Frameworks Overview

        JavaScript is a multi-paradigm language. It supports event-driven, functional, and imperative, including object-oriented and prototype-based, programming styles. JavaScript was initially used only for client side. These days JavaScript is used as a server-side programming language as well. To summarize in just one simple sentence — JavaScript is the language of the web.

      • React Token Auth


        Problem


        Authorization is one of the first problems developers face upon starting a new project. And one of the most common types of authorization (from my experience) is the token-based authorization (usually using JWT).


        From my perspective, this article looks like "what I wanted to read two weeks ago". My goal was to write minimalistic and reusable code with a clean and straightforward interface. I had the next requirements for my implementation of the auth management:


        • Tokens should be stored in local storage
        • Tokens should be restored on page reload
        • Access token should be passed in the network requests
        • After expiration access token should be updated by refresh token if the last one is presented
        • React components should have access to the auth information to render appropriate UI
        • The solution should be made with pure React (without Redux, thunk, etc..)

          ReactJS is an open-source JavaScript library designed by Facebook for developing rich and engaging web apps efficiently and quickly with minimal coding.

          The core task of ReactJS is providing the best possible rendering performance. Its strength comes from the focus on the individual elements. Instead of working on the complete web app, ReactJS allows a programmer to break down the complex UI into simpler elements.

          As per a survey conducted by The State of Javascript, React JS has surpassed Angular and others in becoming the most loved Javascript library.

          • Vue.js Is Good, But Is It Better Than Angular or React?

            Vue.js is a JavaScript library for building web interfaces. Combining with some other tools It also becomes a “framework”. Now, from our last blog, you already know that Vue.js is one of the top JavaScript frameworks and it is replacing Angular and React in many cases. This brings in the topic of this blog ‘Vue.js is good, but is it better than Angular or React?


            In case you’ve never heard or used Vue.js before, you are probably thinking: Come on! yet another JavaScript framework! We get it. However, Vue.js is not new in the custom software development domain. It was first released in 2013 and now it has 130549 stars on Github and downloaded a number of times this year.

                Abstract


                Due to the never-ending increase in volume of vehicles surrounding our daily lives, Automatic Number Plate Recognition (ANPR), has become an evolving solution for managing and monitoring vehicles worldwide to enforce rules and prevent criminal activities, such as parking violation, red light violation, speeding, and vehicle theft. Although there is already a variety of public and private methods and libraries that have been developed and are used to achieve the automatic recognition of car license plate numbers around the world, there has not been much focus on making advancements toward a cross platform ANPR solution that supports all vehicle license plates worldwide. This paper introduces the Plate Vision project, a web and mobile application built on Ruby on Rails and React Native, which aims to serve as an alternative ANPR platform that supports detection of all license plates worldwide by utilizing various open source optical character recognition (OCR) libraries and making efficiency optimizations.

                Key words and phrases: ruby, rails, react native, license plate recognition, plate region extraction, optical character recognition (OCR), ANPR.

              • Sidecar for a Code splitting


                  Code splitting. Code splitting is everywhere. However, why? Just because there is too much of javascript nowadays, and not all are in use at the same point in time.


                  JS is a very heavy thing. Not for your iPhone Xs or brand new i9 laptop, but for millions(probably billions) of slower devices owners. Or, at least, for your watches.


                  So — JS is bad, but what would happen if we just disable it — the problem would be gone… for some sites, and be gone "with sites" for the React-based ones. But anyway — there are sites, which could work without JS… and there is something we should learn from them...

                  Get in the sidecar!
                • React Code Splitting in 2019

                    It's 2019! Everybody thinks they know code splitting. So - let's double check!



                    What does code splitting stand for?


                    In short – code splitting is just about not loading a whole thing. Then you are reading this page you don't have to load a whole site. When you are selecting a single row from a database – you don't have to take all.
                    Obvious? Code splitting is also quite obvious, just not about your data, but your code.

                  • Functional components with React Hooks. Why it's better?

                      When React.js 16.8 was released we got the opportunity to use React Hooks. Hooks make us able to write fully-functional components using functions. We can use all React.js features and do in in more convenient way.


                      A lot of people don't agree with Hooks conception. In this article I'd like to tell about some important advantages React Hooks give you and why we need to write with Hooks.


                      I will not talk about how to use hooks. It is not very important for the examples. If you want to read something on this topic, you can use official documentation. Also, if this topic will be interesting for you, I will write more about Hooks.

                    • Translating Dust templates to JSX



                        Hello Habr! I'm Miloš from Badoo, and this is my first Habr post, originally published in our tech blog. Hope you like it, and please share and comment if you have any questions

                        So… React, amirite???

                        It appeared in the middle of the decade (plagued by the endless JavaScript framework wars), embraced the DOM, shocked everyone by mixing HTML with JavaScript and transformed the web development landscape beyond recognition.

                        All those accomplishments, without even being a framework.

                        Love it or hate it, React does one job really well, and that is HTML templating. Together with a great community and a healthy ecosystem, it’s not hard to see why it became one of the most popular and influential JavaScript libraries, if not the most popular one of all.

                      • (in)Finite War

                          infitite war


                          We have a problem. The problem with testing. The problem with testing React components, and it is quite fundamental. It’s about the difference between unit testing and integration testing. It’s about the difference between what we call unit testing and what we call integration testing, the size and the scope.


                          It's not about testing itself, but about Component Architecture. About the difference between testing components, standalone libraries, and final applications.


                          Everyone knows how to test simple components(they are simple), probably know how to test Applications(E2E). How to test Finite and Infinite things…

                          But... no, nobody knows actually.
