Horizontal scroll animations in React Native – codeburst

  • Horizontal scroll animations in React NativeLink Animated with ScrollView to create a nice navigation UI animation in React NativeWhat we will be buildingRN lets you build a nice and smooth UIWhat you will needReact NativeSimulatorNo third party libraries required :)Creating Screen component with AnimatedFirst, import Animated, Dimensions, ScrollView, StyleSheet, Text, View from “react-native” .
  • Next, create a component that will be treated as a screen or a view.We are using Animated.View here because we are going to animate that wrapper component.That width ofscrollPage style and are important because we are going to interpolate horizontal scrolling values to multiple animation values.
  • In other words, we are going to track where the screen is and animate the screen component based on that value.It’s one of the things that are tricky to explain in words, but it is the key concept to understand for this to work.Basically, we link animations based on the…
  • When the scroll position is at 150, first screen is half way done exiting, and the second screen is half way done entering.Adding animationsSince they are all set up, it is time to write the animations.
  • You would have to write a different inputRange since FlatList removes items that scroll way off screen.I think this is pretty neat UI animation that’s pretty simple to use.

Passing Functions to Components

  • Pass event handlers and other functions as props to child components: – – If you need to have access to the parent component in the handler, you also need to bind the function to the component instance (see below).
  • There are several ways to make sure functions have access to component attributes like and , depending on which syntax and build steps you are using.
  • In JavaScript, these two code snippets are not equivalent: – – Binding methods helps ensure that the second snippet works the same way as the first one.
  • Make sure you aren’t calling the function when you pass it to the component: – – Instead, pass the function itself (without parens): – – You can use an arrow function to wrap around an event handler and pass parameters: – – This is equivalent to calling : – -…
  • is a way of queuing a function to be executed in the browser at the optimal time for rendering performance.

If you need to have access to the parent component in the handler, you also need to bind the function to the component instance (see below).

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

Why Do Developers Now Compare #VueJS To #JavaScript Giants #AngularJS And #ReactJS?

  • 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

Want to Build Progressive Web Apps Based on WordPress and WooCommerce? Here’s How (w/ Code Examples)

How to Build Progressive Web Apps Based on WP and WooCommerce  #webdev #wordpress #reactjs

  • The render method just returns another custom component called  that receives the categories data and looks like this: – – The above component iterates over the list of categories that it receives as a prop and calls another custom component called to render a single category element.
  • First, we need to make the connection with Redux by wrapping our main app component into a global store: – – In this example, the global app store will contain a list of categories and a list of products, which are merged together using the method from Redux.
  • The reducer is just a function that listens to particular actions and changes a portion of the global state, in this case the list of products.
  • That’s because the product list component is directly linked to the global app state, also using Redux.
  • In this way, it can access the products data directly from the app store, iterate over the list of products and use a component to render a single product element.

Progressive Web Apps combine the best of the web and the best of apps. Here’s how to build them on WordPress and WooCommerce (code examples).

  • But for a feature rich app experience, it’s just not going to give good enough results.Even Facebook initially built their app as a mobile web app to be able to roll out features faster, but eventually switched back to native.Write once, build nativeIf each native platform needs code written in it’s…
  • Microsoft has invested heavily in cross platform mobile tooling, because as less than 1% of the global market for mobile devices, no one is going to build apps for just their platform alone.A slightly different approach is used by React Native (and Native Script).
  • While the word hybrid is certainly apt, React Native works so differently from the HTML based hybrid app options, I’d like to think of it as different class instead, with it’s main characteristic being the way it plays puppeteer to the native interface.The way that this works in practice is…
  • If your JavaScript decides to make the header bar change colour, it sends a message to the main native app thread, saying “the header bar should be red now”, and the native header bar widget changes it’s colour to red.This is only different from truly native mobile in a few…
