Why Do Developers Now Compare Vue.js to JavaScript Giants Angular and React?

  • It was 2016 when Vue.js rose to fame and gained so much traction that it’s now seen as an alternative for even well established JavaScript libraries, such as Angular and React.
  • Since Angular belongs to search engine giant Google and React comes from social media behemoth Facebook, developers still trust and use those libraries more than Vue.js.
  • This blog attempts to shed light on why there is a growing belief among developers that Vue.js is set to become the top JavaScript library, leaving behind Angular and React.
  • The reason many developers are turning to Vue is that it addresses the issues of React and Angular.
  • But, one must not forget that Angular and React are still very big names in the JavaScript world, whereas Vue has just begun to rise.

Vue.js, an MIT-licensed open source project, is a JavaScript library for building web interfaces. The library was first released in 2013, but not many developers took cognizance of it in web framework technology for the next two years. It was 2016 wh

5 Best JavaScript Frameworks

Which #JavaScript framework is the best for you? @Da14_team #ReactJS #AngularJS

  • In the meanwhile, JavaScript web frameworks can become a silver bullet for quick web app development.
  • Angular.js is often referred to as an MVW (Model-View-Whatever) framework and among the top benefits, for startups and mid-sized companies, people name: quick code production, easy testing of any app part and two-way data binding (changes in the backend are immediately reflected on the UI).
  • As for now, it is reasonably called the most used JS framework for SPAs (Single-Page Applications) development and it boasts the largest community of developers.
  • Back in 2015 Ember was called the best javascript framework for web application, leaving behind React and AngularJS.
  • When it comes to quick web development or prototyping, JavaScript frameworks are among the most favorable and 2017 won’t become an exception.

The Observer Pattern In Javascript

  • The observer pattern, also referred to as the publish/subscribe pattern, is a design pattern where an object (called the subject or observable), will maintain a list of “dependents” called observers.
  • This video is a good summary of the Observer pattern chapter in the book Head First Design Patterns book.

    Redux: A use case for the observer pattern
    If you work in the world of React, you have probably dealt with Redux to manage the state of your application.

  • Redux is an implementation of the observer pattern.
  • This method “pushes” new subscribers to the array

    const subscribe = (listener) = (

    Remember that subscribe is called in the componentDidMount method which fires immediately after the component mounts.

  • Themes in React Nativetheme provider and UI elementsWhen developing a large scale app it is a good idea to build our own UI components.
  • The styles should be factored out to be DRY.ContextReact context is a suitable tool for dependency injection.
  • Let’s inject our theme.ThemeProvider theme={lightTheme} ButtonTap param is props, 2nd is context.contextTypes has to be defined in order to receive properties in context.
  • Otherwise context will be empty.const Button = ({ text }, { theme }) = ( TouchableHighlight Text style={{ theme.color }}{text}/Text = { theme: PropTypes.shape({ color: PropTypes.string })}ThemeProviderThe return value of getChildContext() will be propagated to its children down the component tree as context.childContextTypes property is needed to defined.class ThemeProvider extends React.Component { getChildContext() { return { theme: this.props.theme } } render() { return this.props.children = { theme: PropTypes.shape({ color: PropTypes.string })}Change ThemesThemes can be changed through props.

How to make Jenkins build NodeJS, Ruby, and Maven on Docker

How To Make Jenkins Build #NodeJS, #Ruby, And #Maven On #Docker  #reactjs #devops

  • Jenkins can speed up repetitive tasks that robots are much better performing and Docker simplifies spinning up VM’s for your application in a very simple and repeatable way.
  • What I’m going to cover here is how to setup your Jenkins server in a Docker container and how to fix some of the limits of the Jenkins official image.
  • While it is nice of Jenkins to offer an official docker image, you’ll quickly run into a few issues if you are doing anything even slightly other than compiling plain Java.
  • For instance, Maven, the popular dependency management tool for Java, is not included in the Docker container.
  • You’ve learned to create a Jenkins Docker-container that’s ready to run jobs for Java, Ruby and NodeJS projects.

Setup your Jenkins server in a Docker container and fix some of the limits of the official image I discovered so you can get up and building faster.

React Native Node: Run a Separate Node Process Behind a React Native App –

  • Run a real Node.js process in the background, behind a React Native app.
  • Using this package you can: run servers in Android, use Node streams, interface with the filesystem, off load some heavy processing out of the JS thread in React Native, and more!
  • Running the real Node.js in Android, you can do everything that Node.js on desktop can.
  • If you want to bundle and insert the background app always before building the mobile app, make a package.json script (assuming you use the script):

    You can reduce the size of the bundle file by using a tool like noderify to create a single js file.

  • These are in turn used by the mobile app project mmmmm.
