Introduction to ReactJS

  • ReactJS focuses only on the rendering of View (part of MVC), as it does not implement the entire MVC pattern, but tightly focuses on the development of components (views) which are displayed on the user-interface so that it is more efficient in developing dynamic and interactive user-interfaces and its components….
  • Traditionally, when we used to change the data (model in MVC) at server-side, we used to reload the entire page (at client-side) to implement or reflect the updates from the server, which make processing very slow and creates bad user-experiences.
  • But ReactJS has solved these issues as it works at the client-side and takes care of the updates from the server by just changing those particular components or parts of interfaces which are changed, and it does not reload the entire page.
  • DOM (Document Object Model) is the user-interface or HTML document which is rendered or displayed on the screen, and if we have to rerender the entire DOM every time to reflect the changes that come from the server, it would be very expensive and take many CPU-cycles and processor time….
  • To overcome these issues, ReactJS creates Virtual DOMs in memory and whenever any data is changed at the server, ReactJS rewrites the Virtual DOM, and then it performs “diff” operations between all Virtual DOMs… one which was created initially and the other which is created after the change of data….

ReactJS is a JavaScript library used to develop dynamic user-interfaces or the components of user-interfaces like search bars, sliders, and widgets in web applications. ReactJS focuses only on the…

Vue.js, React Native, Node.js and JS Testing – Bulgaria Web Summit 2018 – Medium

  • Talk by Kaloyan Kosev: React Native App — Expectations vs Reality.superKaloI had a chance to be part of a team that started developing a decent size React Native mobile app from scratch.
  • As a developer with a solid React background, I had some expectations at first.
  • During my initial research, everything sounded terrific: performance stats, ease of development, learn-once-use-everywhere, debugging tools, etc.
  • But is everything terrific really?I’m excited to share my journey about how my expectations met the reality.
  • I’ll also try to address the most popular misconceptions about React Native, which front-end developers usually have before they have the chance to actually built something.

As the applications we write tests against grow more complex we might stumble into testing errors stemming from asynchronous and time-dependent behaviour. This talk will characterize several…

React Native: A new competitor to native development?

React Native: A new competitor to native development?  #reactnative #tech

  • So, what advantages and disadvantages of React Native app development can we distinguish?
  • Many mobile IT companies consider the ability to develop cross-platform apps as the main advantage of React Native.
  • Therefore, when building an app with React Native framework, developers operate with blocks that can be easily managed.
  • Moreover, as its library only grows with each coming year, it becomes more and more beneficial and easy to use React Native in your mobile development.
  • One of React Native’s main advantages is the possibility to reuse code and build mobile apps for both Android and iOS platforms at the same time.

React Native is only two years old but it has already proved its usefulness. Lolita Rogers weighs in on the advantages and disadvantages.

Rails, React and me – codeburst

  • It uses rails to include only JS and Webpack compiled files which was perfect match for the use case.Figuring solutions is always easy, The difficult part is to figure out the problemReact_on_rails has given the instructions to setup existing rails project so I started with them but ran into many…
  • In this particular case, figuring out the problem became worse as the errors were misleading.The Aha Moment: Devil was in the detailsFinally to figure out the problem I created a sample project from scratch using react_on_rails new project setup instructions and started comparing the generated code with my existing project.
  • This particular information turned out to be crucial to get out of the problem I was facing which I was not aware of at that time.SolutionTo solve this issue just change your API controller to base controller.
  • Though I would suggest to convert your entire rails-5 api only app to normal rails app.
  • Once you have resolved everything run$bundle installThis will convert your rails-5 API only app to rails app which can easily be integrated with react_on_rails.

Introducing React Native Android Fragment – In The Hudl – Medium

  • So today we are announcing our first open source project for React Native at Hudl.React Native Android Fragment: Native Android Fragment does exactly what its name implies.
  • It helps to facilitate the development of a React Native application, for a pre-existing Android application that relies on the framework’s Fragment class.
  • It can be downloaded via jitpack and its versioning will attempt to always follow that of React Native’s major.minor versions.Our Android app originated around 2013 when Fragments were the Android standard and we’ve stuck with them ever since.
  • For anyone else that has tried to use React Native, you may also realize that support for Fragments is non-existent.
  • We hope this library, although small, may help others to get started quickly into the React Native ecosystem.

What are the reasons for using EmberJs? – Gazar JavaScript Blog – Medium

What are the reasons for using #EmberJS?  #Ember #framework #JavaScript #React #ReactJS

  • EmberJs, What is the feeling when you hear something about emberJs?
  • If you are a front-end developer, it is most likely to use React or Angular2,4!
  • Although, there are still so many doubts about choosing this framework.Did you know these popular websites are using Ember?Apple Music, Yahoo!
  • , LinkedIn, TinderBox, Netflix, GrouponWhat are the differences?Firstly, Ember is a fully opinionated framework, compare to react which is just a library for updating DOM.Secondly, EmberJs has a powerful CLI for creating anything like models and controllers.Thirdly, Facebook has developed React, but, this team is responsible for maintaining Ember.Of course, there are so many technical differences rather than these three points ( You can read more about them here ), however, I just wanted to mention general and bold ones.At the end:Both frameworks are so great in development and there are so many known products written with them.
  • As I see, there are two reasons for selecting React over Ember:You are a developer who wants to have your own structure and opinion for your product.Your company feels better when they hear about Facebook behind ReactJs.Choose React, if you have one of these reasons, otherwise, Ember definitely is a better choice over ReactJs.I have been using React because of the first reason and I think this would be a reason of so many others.What do you think?

What? EmberJs, What is the feeling when you hear something about emberJs? If you are a front-end developer, it is most likely to use React or Angular2,4! or 5? nowadays!
But what is wrong with…
