React Show

A css powered (graphics accelerated) animation component for React.

Why?

You need to animate, reveal, collapse your react components. Everyone does!
You want it smoothly animated, even on mobile. Like butter on a glide-cam!
You don't want to bloat your app with custom physics-based animation frameworks, request-animation-frame-happy animation loops or even jQuery...heaven forbid.

Features

3.7 kb gzipped
Powered by native CSS animations & transitions on the GPU when possible
Animates height: auto; and width: auto;

Installation

$ yarn add react-show # or $ npm install --save react-show

Usage

Simple Usage

You can create a simple expander component with the Animate component!

import { Animate } from "react-show";  const SimpleExample = () => (   <Animate     show={true || false} // Toggle true or false to show or hide the content!     duration={500}     style={{       height: "auto"     }}     start={{       height: 0 // The starting style for the component.       // If the 'leave' prop isn't defined, 'start' is reused!     }}   >     Hello world!   </Animate> );

Advanced Usage

You can create a simple expander component with the Animate component!

import { Animate } from "react-show";  const SimpleExample = () => (   <Animate     show={true || false} // Toggle true or false to show or hide the content!     transitionOnMount // Will trigger the transition when the component is mounted and show === true     preMount // Mounts the component's children on first render even if show === false     stayMounted // Forces the component's children to remain mounted when show === false     component="span" // Use a <span> (or custom) component as the wrapper instead of a <div>     style={{       // The permanent styles for the component       height: `${Math.random() * 100}px`,       background: "white"     }}     start={{       // The starting styles for the hidden component.       opacity: 0,       height: 0     }}     enter={{       // These styles will be applied when the component enters       opacity: 1,       height: 'auto'       background: "green"     }}     leave={{       // these styles will be applied when the component leaves       opacity: 0,       height: 0,       background: "red"     }}   >     Hello world!   </Animate> );

Duration, Easing, Transition Properties

You can configure duration, easing, and transition by:

Setting a component-wide default with the duration, easing, and transitionProperty props.
Optionally using a lifecycle specific style property like transitionDuration, transitionTimingFunction, transitionProperty or even transitionDelay.

ReactShow comes with a wide variety of easings built-in! See Easing Options for a full list.

import { Animate } from "react-show";  const DurationAndEasingExample = () => (   <Animate     show={true || false} // Toggle true or false to show or hide the content!     duration={500} // // The duration of the transition in milliseconds     easing={Animate.easings.easeOutQuad} // Comes with all the easings you could want!     enter={{       // Only use this duration/delay during the `enter` stage       transitionDuration: ".3s",       transitionDelay: "1s"     }}   >     Hello world!   </Animate> );

Lifecycle

React-Show uses the following lifecycle to determine which styles to show:

When show === true

If component is not mounted
- If transitionOnMount === true
  - The start styles are set as the initial style
- If transitionOnMount === false
  - The enter styles are set as the initial style
- The component is mounted
If component is already mounted
- The enter styles are set as the initial style
If a width or height style is/was set to auto
- The display: block and overflow: hidden styles are temporarily applied
- The component scrollWidth/scrollHeight is measured
- The display: block and overflow: hidden styles are removed
The enter styles are applied and component waits until all transitions complete
All lifecycle styles are removed and component waits until all transitions complete
The onFinish prop function is fired

When show === false

If a width or height style is/was set to auto
- The display: block and overflow: hidden styles are temporarily applied
- The component scrollWidth/scrollHeight is measured
- The display: block and overflow: hidden styles are removed
The leave or start styles are applied and component waits until all transitions complete
If stayMounted === false
- The component is unmounted

Easing Options

React-Show comes packaged with some awesome easings that are accessible via Animate.easings. They are extremely simple to use too:

import { Animate } from "react-show";  const SimpleExample = () => (   <Animate show={true} easing={Animate.easings.easeOutQuart}>     Hello world!   </Animate> );

Below is a full list of the available easings exported at Animate.easings

import { easings } from "react-show";  easings ===   {     // Cubic     easeInCubic: "cubic-bezier(0.550, 0.055, 0.675, 0.190)",     easeOutCubic: "cubic-bezier(0.215, 0.610, 0.355, 1.000)",     easeInOutCubic: "cubic-bezier(0.645, 0.045, 0.355, 1.000)",      // Circ     easeInCirc: "cubic-bezier(0.600, 0.040, 0.980, 0.335)",     easeOutCirc: "cubic-bezier(0.075, 0.820, 0.165, 1.000)",     easeInOutCirc: "cubic-bezier(0.785, 0.135, 0.150, 0.860)",      // Expo     easeInExpo: "cubic-bezier(0.950, 0.050, 0.795, 0.035)",     easeOutExpo: "cubic-bezier(0.190, 1.000, 0.220, 1.000)",     easeInOutExpo: "cubic-bezier(1.000, 0.000, 0.000, 1.000)",      // Quad     easeInQuad: "cubic-bezier(0.550, 0.085, 0.680, 0.530)",     easeOutQuad: "cubic-bezier(0.250, 0.460, 0.450, 0.940)",     easeInOutQuad: "cubic-bezier(0.455, 0.030, 0.515, 0.955)",      // Quart     easeInQuart: "cubic-bezier(0.895, 0.030, 0.685, 0.220)",     easeOutQuart: "cubic-bezier(0.165, 0.840, 0.440, 1.000)",     easeInOutQuart: "cubic-bezier(0.770, 0.000, 0.175, 1.000)",      // Quint     easeInQuint: "cubic-bezier(0.755, 0.050, 0.855, 0.060)",     easeOutQuint: "cubic-bezier(0.230, 1.000, 0.320, 1.000)",     easeInOutQuint: "cubic-bezier(0.860, 0.000, 0.070, 1.000)",      // Sine     easeInSine: "cubic-bezier(0.470, 0.000, 0.745, 0.715)",     easeOutSine: "cubic-bezier(0.390, 0.575, 0.565, 1.000)",     easeInOutSine: "cubic-bezier(0.445, 0.050, 0.550, 0.950)",      // Back     easeInBack: "cubic-bezier(0.600, -0.280, 0.735, 0.045)",     easeOutBack: "cubic-bezier(0.175,  0.885, 0.320, 1.275)",     easeInOutBack: "cubic-bezier(0.680, -0.550, 0.265, 1.550)"   };
