How to solve an UI anti pattern with React ? A great post by @sharifsbeat  #ReactJS

  • Setting the items to null instead of an empty array creates even more problems so that won’t help either.Stefan Oestreicher, Slaying a UI Antipattern in FantasylandSo we have to manually keep track of the current data status, making sure we don’t forget to set the correct loading, error and data…
  • Forgetting to keep the state in sync leads to a false representation in the UI.In Slaying a UI Antipattern in Fantasyland we are represented with a different way to think about the problem:type RemoteData e a = NotAsked | Loading | Failure e | Success aWe might have different states…
  • By modelling all possible states, we can resort to using daggy f.e., which enables us to handle the possible outcomes.const RemoteData = daggy.taggedSum({ NotAsked: [], Loading: [], Failure: [‘error’], Success: [‘items’],})// in our constructorthis.state = { items: RemoteData.NotAsked }(* Taken from Slaying a UI Antipattern in Fantasyland)By now we should…

Getting Started With React Programming

Getting Started With #ReactProgramming by @KumarPraveen179 cc @CsharpCorner  #Reactjs

  • You should know the basic concepts of JavaScript like – – – Basically, it is a JavaScript library for building user interfaces.
  • We can say that it’s a new type of JS library, offering a new approach to build/update a View.
  • It creates a virtual DOM to track the changes when the application state is updated and uses the virtual DOM to update only those parts of a page which have been changed.
  • It was first deployed on Facebook’s Newsfeed in 2011 and after that, on – – Where To Use React – – As we discussed above, it’s a JavaScript library so, it is possible to use React everywhere where JavaScript code can be executed.
  • In the upcoming article, I will explain more about virtual DOM using programming example along with the graphical view.

React is a JavaScript library for building user interfaces. It is developed by Facebook to facilitate the building with the interactive, stateful and reusable UI components.

Building a new backend — Part 1 – lookapanda – Medium

Building a new backend — Part 1  #discord #webdevelopment #react #javascript #node #reactjs

  • Building a new backend — Part 1In this story I’d like to document my experiences in building a new backend.It represents my personal experiences and is not related to my profession as a Software Engineer.What is the backend for?This is a legitimate question, of course.
  • There is no real goal yet, I see it more like a personal challenge and practice.Some of my first pieces of code using LaravelI already built a backend quite some time ago already written in PHP using Laravel.
  • Times change quickly in a developers world and today I’m mostly programming in JavaScript (ES6, Node, etc.) and not that much in PHP anymore.Today (2017) I want to create something new again using the most modern technologies I can find.
  • REST APIs access information after all and said information needs to be stored somewhere.With my PHP API I was using MySQL (or actually MariaDB) and with my Node API it was MongoDB.
  • It should be easy to use but also powerful.In my next blog post I will share my first experiences in using Cassandra for building the database and probably also my decission for the framework I’ll be using.If you’ve come so far to read this very line, I want to say thank you.

React Native: What to Expect

React Native: What to Expect  #reactnative #ios #android

  • People start using it for many reasons, including:

    As you build a skillset working with React Native, much of that knowledge can be leveraged for web development via React.

  • If we compare with other Javascript mobile frameworks like Ionic and NativeScript, React Native is number one in popularity on GitHub.
  • There are a lot of real world apps using React Native, such as Instagram, Airbnb, Walmart, and many more!
  • If you’re looking to develop mobile apps for iOS and Android, React Native is worth a try.
  • Our first React Native Remote Meetup is happening on soon, and it’s a great way to meet other React Native developers and stay up to date on what is happening in the community.
