How to Animate the Items of a React Native FlatList

  • 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.
  • 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.
  • Inside the render function we use the animated value to adjust the opacity and scale (directly, because 0 to 1 is what we’re looking for) and the rotation.
  • We’re now left with some subtle, yet slick, animations for each row item for whenever they’re added or removed.

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…

  • You can apply CSS to your Pen from any stylesheet on the web.
  • Just put a URL to it here and we’ll apply it, in the order you have them, before the CSS in the Pen itself.
  • If the stylesheet you link to has the file extension of a preprocessor, we’ll attempt to process it before applying.
  • You can also link to another Pen here, and we’ll pull the CSS from that Pen and include it.
  • If it’s using a matching preprocessor, we’ll combine the code before preprocessing, so you can use the linked Pen as a true dependency.

Working on some tight, clean, minimal interaction….

I18n with React and i18next ← Alligator.io

I18n with React and i18next  #ReactJS

  • A 30,000 foot view of i18next would be that it provides a function that takes a key, some options, and returns the value for the current language.
  • Because the function will likely be called several times in an app, the creators of i18next have chosen a shortname: – which is short for translate.
  • Although i18next is designed to work with many frameworks, this post will focus on how to internationalize a React app using i18next.
  • In order to use i18next with React, the function needs to be made available to the components that need to be internationalized.
  • The React binding for i18next provides the component.

A brief introduction to internationalizing a React app using i18next.

  • Those remain the same and intact.While this sounds like no more can be achieved from a library that was mostly about best practices and common patterns in CSS, we are still in a position to drive change in the community.And this is because of the ecosystem that people have created…
  • Even more so with our new docs that we’ve published a few months ago.But the real question is, what makes it the library you know and love?There’s a lot of great content and talks from both Max and Glen, so if you’re new to what the ideas of the library are,…
  • [1]Then we have to transform the CSS to be able to inject it [2], and finally inject your CSS into the stylesheet, at the position that we’ve marked earlier.In v2 and onwards we’ve focused a lot on optimising all of the different steps involved here for performance, but one step…
  • The idea that becomes increasingly important here is, that we can’t build a library that works for some special use cases, but what we can build is a CSS infrastructure that allows you to change the CSS yourself.Let’s see how we could approach this.The interesting thing is that with v1…
  • We can run our transformations during Babel’s transpilation, or during build-time in general.We can build a CSS-in-JS pipeline!This would result in nothing being shipped to the runtime, and as long as we can provide an “opt-in” system, you would still be able to decide whether you’d like to ship the…

styled-components has changed a lot in its past. And we are not even done yet!

Part 1: Getting Started With React Native

Ch 11

  • React Native just may be the holy grail of cross-platform app development that many developers and companies have been hoping for.
  • Using React Native, developers can build performant cross-platform native apps much easier than ever before, all with a single programming language: JavaScript.
  • With the growing demand for apps and the increasing complexity that app development entails, React Native comes along at a perfect time.
  • If you’re serious about app development or want to stay ahead of the curve on emerging and disruptive technologies, take a look at React Native.
  • “Great introduction to the rapidly changing world of React and React Native!”

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!
