Why do we need to understand the ReactJs life cycle methods?

Why do we need to understand the ReactJs life cycle methods?  #javascript

  • When you build an application in ReactJs you will have to split the UI into reusable components and think about each of them in isolation.When the user interacts with our application in ReactJs, for example, by hovering, pressing a key, clicking… These actions trigger many other events on the UI…
  • So, why is understanding lifecycle methods so important?Let’s imagine that you are building an application in ReactJs, for example, a video player app, like Vimeo, Twitch or Youtube .
  • Now, your user is using the player app on his/her laptop and decides to search for a fun video to watch, found the video, and then selected to watch it.Let’s suppose that the player app is consuming only resources like network data and the battery power.After some time watching videos…
  • When we build an application in ReactJs , we can predict different type of actions by the user, placing some hooks and triggers.These triggers and hooks are available by component lifecycle methods in Reactjs.
  • They will help us to create the most efficient piece of the software as possible.To place correctly the hook methods into the components we need to learn more about the four stages of ReactJs component.The ReactJs component goes through the Four following is a little diagram to demonstrate those phases.InitializationIn…

Components are the core of ReactJs. When you build an application in ReactJs you will have to split the UI into reusable components and think about each of them in isolation. When the user interacts…

No Bundle URL Present – Joshua Kuhar – Medium

No Bundle URL Present  #ios #reactnative #reactjs #reactjs

  • No Bundle URL PresentAfter you create a production build for React Native iOS, you might get No Bundle URL Present when reverting to developmentThe instructions for creating a production build for a React Native iOS app are located in the docs here, under the section Building your app for production.However, when…
  • If not done properly, you might encounter the error message below.When resetting the NSAppTransportSecurity properly in the Info.plist file, syntax errors and their ilk are easy to evoke.
  • I was using Sublime for my text editor.Below was the default configuration in the Info.plist file when the project was created with React Native.
  • This was the code I pasted back in to remove the No Bundle URL Present dict keyNSExceptionDomains/key dict keylocalhost/key dict true/ /dict /dict /dictFor a good explanation of app transport security, see this article by Steve Peterson.The Info.plist file can usually be located in your React Native project root /ios/appName/Info….
  • Lastly, this solution was only used for a manual configuration and not by React Native CLI.

What is the best editor for my needs? – arkulpa – Medium

What is the best editor for my needs?  #php #javascript #emberjs #react #atom #reactjs

  • What is the best editor for my needs?In 2013 we started our company arkulpa, most of the time I spent with coding PHP and some simple JavaScript.
  • All I needed that time…But then I slowly switched from PHP to do more and more JavaScript.
  • But often I wasn’t very happy with the JavaScript performance of PhpStorm so I tried other editors and the editor carousel started.the editor carouselAtom, Visual Studio Code, vim and PhpStormReally important for me is good formatted code, lint support, autocompletion and I want to use the same editor for all languages.All of my needs should be combined with good performance ;)First I tried Atom → then I switched to Visual Studio Code → then I tried to use vim → went back to Atom → switched to PhpStorm → tried to get PHP support running for Visual Studio Code → gave vim another try→ went back to Atom …Currently I am fine with Atom,…I went away from Atom first and second time because of not really working code formatting with JS and JSX.
  • Then two weeks ago I read a pull request from create react app that was the first time I read about prettier.
  • Now I’m using the prettier-atom plugin in combination with ESLint, also disabled all formatting from language-babel and it works really great!The list of plugins I useI use Atom for developing new stuff with React, Node.js and Ember.js and for maintaining older projects with PHP/Symfony.

In 2013 we started our company arkulpa, most of the time I spent with coding PHP and some simple JavaScript. At this time I was really happy with using PhpStorm. It has great features for PHP…

Use ESLint Like a Pro with ES6 and React – Zsolt Nagy

Use ESLint like a pro with ES6 and #ReactJS:

  • The file .eslintrc is a JSON file responsible for configuring your individual linting rules.
  • Each import would result in a linting error.
  • Using the “translate_tabs_to_spaces” key neutralizes the default linting rule “no-mixed-spaces-and-tabs” .
  • As our code is guarded by linting rules, we are guaranteed to produce consistent code, increasing maintainability.
  • The site uses cookies More info

ESLint helps us catch mistakes by enforcing consistent standards and best practices. As our code is guarded by linting rules, we are guaranteed to produce consistent code, increasing maintainability.
