Animations In React.js – Duncan maina – Medium

Animations In React.js  #javascript

  • ReactCSSTransitionGroup requires three elements to work.A ReactCSSTransitionGroup elementAt least one item to render outCss to specify the animation type.The ReactCSSTransitionGroup element wraps the content that you want to appear with css transitionName=”example” …transition options… { items } /ReactCSSTransitionGroupThis element must be initiated with a transitionName, which tells react which css animation to render out.
  • The transitionName gets translated to a class name that you select in css, followed by the transition property..example-appear { opacity: { opacity: 1; transition: opacity 2s ease-in;}In this example the element will fade in from the background starting at an opacity of 0.01 to an opacity of 1 in two seconds.React.js allows you to set animations to elements in your react application with ReactCSSTransitionGroup api.
  • This allows other developers to get an idea of the exact state of the program at any given time.ReactCSSTransitionGroup works well for simple css animations but other options exist for more complex animations ie: animations that involve motion.
  • It also contains many of the popular animations styles such as: bouceOut, bounce, bounceIn, fadeIn , fadeOut , flip , headShake , jello, rotateOut , rotateOutDownLeft , rotateOutDownRight , rubberBand , { bounce } from ‘react-animations’;import { StyleSheet, css } from ‘aphrodite’;const styles = StyleSheet.create({ bounce: { animationName: bounce, animationDuration: ‘1s’ }})try them out at : for a full list of animations and instructions on usage see Motion: a javascript library that handles the physics of component animation and provides an easy to use api for accessing those animations.
  • find more information here: Nash Vail also wrote a great tutorial on motion that can be found here: defaultStyle={{x: 0}} style={{x: spring(10)}} {interpolatingStyle = div style={interpolatingStyle} /}/MotionReact Flip Move: react flip move is a library that allows you to animate flips for your react components.

Css Animations in react.js are handled through the ReactCSSTransitionGroup Api. It provides a way to perform css when components enter or leave the DOM. ReactCSSTransitionGroup requires three…

A Glimpse Into The Future With React Native For Web – Smashing Magazine

A Glimpse Into The Future With React Native For Web – @smashingmag

  • We have already seen how1 React Native can help you make iOS and Android apps with a shared code base, without sacrifices in quality.
  • React Native for Web is intended to let you write a single app that runs in a browser using standard web technologies, or on iOS and Android as a real native mobile app.
  • React Native for Web’s solution is to provide browser-compatible implementations of React Native’s components — meaning, for example, that the of React Native has a DOM-based version that knows how to render to a .
  • At this point, your file should look something like this:

    While we have what seems to be everything required for our React Native app to run in a web browser, we must take a brief detour to consider the realities of web development.

  • This will be a good simple stress test of React Native for Web, because we need to use a few different components for it: , , and .

react + d3 = vx – vx code – Medium

react + d3 = vx - A new data visualization library for #reactjs by @hshoff

  • You just need to use d3 and magic dances across your screen.Of course, the last time you made a chart with d3 was 3 or was it 4 years ago?
  • “I wish there was something more like d3 I could use,” you say.Enter vxreact + d3 = vxMixing two ways to update the DOM is never a good time.
  • Me too.So I set out making a library of low-level components that could be used to build up reusable charts or those one-off requests or that special idea you had for a visualization that you’ve never seen done before.About vxGoal The goal is to create a library of components you can use to make both your own reusable chart library or your slick custom one-off chart.
  • If you’re creating your own awesome chart library on top of vx, it’s easy to create a component api that hides d3 entirely.
  • The vx collection of components lets you easily build your own reusable visualization charts or library without having to learn d3.

You’ve fallen in love with React. You’ve built a redux app. You’ve dabbled with GraphQL. You’ve started following along with Relay Modern and Apollo Client. But your next project is a dashboard that…

React + D3.js: Balancing Performance & Developer Experience

#ReactJS + D3.js: Balancing performance & developer experience  #JavaScript

  • The idea is still to use D3’s helpers and JSX to render SVG elements, except that now the elements rendered by React are rendered without attributes, and D3 is used to add their attributes.
  • Each of these methods can use typical D3 code to position, style, and transition elements.There are some caveats to this approach:As declared in the post introducing this idea, exit() transitions are not supported without bringing in React’s TransitionGroup.Since React does not keep track of attributes, we have to manually implement state comparison to detect when the component should update in order to call the update() method performing D3 transitions.
  • I believe this is due to the need to split the code according to the line of ownership between React and D3, instead of splitting it into logical units.Solution 3 — Feed D3 a fake DOM that renders to stateThis is the solution I found the most elegant so far, and it is what powers the demo at the beginning of this post.
  • That fake DOM is manipulated by D3 and then automatically rendered as React elements stored into the component’s state where React can pick up changes and kick-off an update, including lifecycle methods and reconciliation as you would expect.I found this approach elegant because both D3 and React are used without alienation.Except for feeding the faux DOM node to D3 instead of using a selector as you normally would, vanilla D3 code can be used.
  • Hence, you get to enjoy the typical render performance of React components.SVG elements are automatically transformed into React elements and are inspectable in the devtools.The implementation is compatible with server-side rendering, so you get isomorphic charts at no cost.Overall, this solution has restored my faith is having a great DX when using D3 visualizations in React components, while making the most out of React’s render performance.

Let’s put it out there, I love dashboards. I find the way they help you gain a rapid understanding out of complex information really interesting. I have written real-time data visualisations in the…

The One Thing you need to know about React Router 4

The One Thing you need to know about #ReactJS Router 4:  by @thegreengreek #JavaScript

  • If you focus on this key point, all the features and functionality that the new format gives you become so much more intuitive to understand.Let’s take a look at a basic example before we dive too much further in:Apply what you already know about Router to BrowserRouter (hence the named import), and Link works the same as well.To get a deeper understanding of Route, I highly recommend diving directly into the API docs.
  • You have three different ways (through props) to tell aRoute what to render: a target component, or functions in render or children that return valid nodes.
  • It’s convenient for animation and cases like when we only want to modify a className based on the route but everything else still needs to render.We call the BrowserRouter once in an application, usually at a high level (just above where we first need to start defining routes and links).
  • For example, say two different geographical areas of your application need to contain content that varies based on the URL.
  • You can define two routes (or as many as you need) to match the same URL in different parts of your application.A Route helps you compose your React applications in a more “React” way.

I finally started a new project using React Router 4. It’s no secret that the churn between versions has been pretty high, and version 4 is no different. However, I think the team at React Training…
