Animate React Native UI Elements

Animate React Native UI Elements course by @browniefed #react

  • In this course we will learn and demonstrate the basic concepts of the React Native Animated API.
  • We’ll use Animated calls like and to animate style properties, and learn how to combine animations to create more complex effects.
  • We’ll learn about more advanced interactions like animations with touch events, interpolation, and flip animations.
  • The ultimate goal is to gain an understanding of how to animate React Native Views, how you can apply them to many different types of styles, and how to enhance the experience in your application.

React JS, Angular & Vue JS

  • There are lots of different frameworks like Angular, React or Vue, libraries and other packages (like webpack).
  • You’ll get an introduction into the three most important JavaScript frameworks (Angular, React.js and Vue.js) and you’ll also get a detailed comparison!
  • This will then allow you to pick other resources or courses to dive super-deep into your chosen framework whilst having a solid foundation already.
  • Throughout the course, we’ll dive into the basics of these frameworks but we’ll also have a look at why we use them to begin with.
  • Not only are we going to dive into the basics of the three most popular JavaScript frameworks, this course will also draw a detailed comparison.

Angular (Angular 2 or 4), React or Vue? Get a Crash Course on each of them and a detailed comparison!

Experiments with High Performance Animation in React Native

Three major methods for shape animation with React Native via @salesforceeng

  • This story is my experience and experiments to achieve high performance animation in React Native.Along the way I learned tons from these blogs and recommend you read them as you dive deeper into building your own animations in React Native:React Native Animations Using Animated API from Nader DabitReact Native ART and D3 from Harry WolffBefore we continue, I would like to define what “high performance animation” in terms of my project.
  • Note: There is another OpenGL binding for React Native which enables a more flexible OpenGL implementation without the interface.Animation in React NativeIn my exploration I tested three major methods (with some variations) for doing shape animation with React Native.
  • For example, if we have a shape with a 1px border, it cannot be transformed to have a larger width/height and retain the same border width without redrawing.Experiments and ResultsRequest Animation Frame + JavaScript tweeningThe first approach is to change nothing but use the same code from the web implementation — meaning everything is done in JavaScript without any help from React Native.
  • The gaps between each country will also get scaled so the transformed shapes are not the same as the new shapes.Zoom animation with fade in/outThis method has a significant impact on the memory footprint since there are two views with a shadow node per shape.Animated + Hybrid Native Driver + Animated Shape (ART)For this approach I still used the Native Driver while I found there is a trick to communicate between the JS thread and UI thread using setNativeProps.
  • I first tried with React Native ART and switched to React Native SVG while both give similar results.Animated + Hybrid Native Driver + Animated Shape (OpenGL)After realizing the bottleneck comes from re-drawing shapes, I switched to another library which has the drawing logic implemented in OpenGL.

Archiving decent animation performance is quite tricky. This story is my experience and experiments to achieve high performance animation in React Native.

How to Animate the Items of a React Native FlatList

  • Be sure to subscribe!Animating EntryTo easily demo our animation we’ll animated to insertion of the list item.
  • When a new item is added to the people array we’ll change the opacity of the row and, via transform, the scale and rotation.It’s important to note that inside the TouchableOpacity we’re using an Animated.View which allows us to modify that component using animated values.First we’ll create a new animated value and, when the component mounts, we’ll change that value from 0 to 1 using Animated.timing.Then we need to drive our UI from these values.
  • We can’t do that in componentWillUnmout because the component will be gone before any animations can run!If you test this out though you’ll see that it doesn’t actually do anything — the row just disappears the same as before.If you comment out the onRemove function you can see that the animation is happening.What we can do is call the onRemove function when the animation completes.
  • We’re now left with some subtle, yet slick, animations for each row item for whenever they’re added or removed.
  • It covers component design, Redux, Redux Saga, and more animations!Want more React Native videos?

I was recently asked about animating items in a React Native list — specifically animating the item when added and removed. That’s what we’ll cover today! To accomplish this we’ll use the FlatList…

  • So always keep the thing in mind otherwise you will end-up with your awesome react code.
  • First thing you have to be clear, React.JS is not an MVC framework or any other kind of framework.
  • We round things out with Webpack for bundling our code, and NPM for package management, and we’re now fully JavaScript buzzword compliant 🙂
  • Many documentations are available online by using then you can set your environment and can start working with React.JS. but before starting big things you have to know some basics.
  • This is the language which makes hard stuff as easy as easy stuff, but sometime it makes easy stuff as hard as hard stuff, which you do by using simple jQuery or Javasript.

React.Js is an emerging programming thing for developers. This is the language which makes hard stuff as easy as easy stuff, but sometime it makes easy stuff as hard as hard stuff, which you do by using simple jQuery or Javasript. Many documentations are available online by using then you can set your environment and can start working with React.JS. but before starting big things you have to know some basics. I learnt some react.JS. sharing my points:
