# react-tweenful

Looking for an amazing React library for animating stuff? Look no more, we've got you covered!

## Demo

https://teodosii.github.io/react-tweenful/

## Features

* Loop support (infinite or up to a specific number)
* Wide variety of easings (bezier, predefined and custom easing)
* Delayed animations (before and after)
* Events support
* Negative delay support to mimic CSS animations
* Percent based animations to mimic CSS animations (e.g. `0%`, `50%`, `100%`)
* `Tweenful` component for animating DOM nodes
* `SVG` component to animate SVG nodes
* `Observer` component for mount/unmount animations
* `ObserverGroup` component to handle child transition (list removal/insertion, page transition etc)

## Getting started

```
npm install react-tweenful
```

### Development

In order to build the project and run it on your local machine, you'll need to build both the `site` project and the library itself. The `site` project will have a dependency of `react-tweenful` and there you'll be able to play with the examples.

```
npm run build:library:dev
npm run start
```

Or if you want to be able to modify both projects at once and let webpack watch the changes and do the build for you, then open 2 separate terminals and run the following commands

```
npm run watch:library:dev
```
And in a separate terminal run
```
npm run start
```

Both commands will instruct webpack to watch for changes.
Navigate to `http://localhost:8080/react-tweenful` or whatever port you're running the application on.

## Usage

`react-tweenful` exports the following:

* `Tweenful` - component to animate DOM elements. It requires a DOM node to perform animation on.
* `SVG` - component to animate SVG elements. It requires a SVG node to perform animation on.
* `Observer` - component to animate mounting and unmounting of an element.
* `ObserverGroup` - component to watch over a list of `Observer` elements such as list removal/insertion or route transition

A couple of utility functions are also exported to help you out animating:

* `percentage` for percentage based animations
* `bezier` for bezier easings
* `elastic` for elastic easing

Import the needed component, for example `Tweenful`

```jsx
import Tweenful, { elastic } from 'react-tweenful';
```

`Tweenful` requires a node to render on which it will perform the animation. We've got most of the DOM nodes covered in the form of namespacing such as `Tweenful.div`, `Tweenful.span` and so on.

```jsx
const Example = () => (
  <Tweenful.div	
    className="tween-box"	
    duration={2000}	
    easing={elastic(1, 0.1)}
    style={{ position: 'relative' }}	
    animate={{ left: ['0px', '250px'] }}
  ></Tweenful.div>
);
```

Voila!

## Examples

### Observer

View animation [here](https://teodosii.github.io/react-tweenful/observer)

Usage of `Observer` component together with `Tweenful`. Animate movement with `Tweenful` and subscribe to mount and unmount with `Observer`.

![Observer](https://github.com/teodosii/react-tweenful/raw/master/gif/observer.gif "Observer")

```jsx
import React, { useEffect, useState } from 'react';
import Tweenful, { Observer, elastic } from 'react-tweenful';

const props = {
  delay: 200,
  render: true,
  duration: 1600,
  easing: elastic(1, 0.1),
  loop: false,
  animate: { translateX: '400px' },
  events: {
    onAnimationStart: () => console.log('AnimationStart'),
    onAnimationEnd: () => console.log('AnimationEnd')
  }
};

const ObserverDemo = () => {
  const [shouldRender, setShouldRender] = useState(true);

useEffect(() => {
    setTimeout(() => setShouldRender(false), 3000);
  }, []);

return (
    <Observer
      render={shouldRender}
      duration={1200}
      style={{ opacity: 0 }}
      mount={{ opacity: 1 }}
      unmount={[{ opacity: 0 }]}
      easing="linear"
    >
      <div className="observer-demo">
        <Tweenful.div className="box-demo" {...props}></Tweenful.div>
      </div>
    </Observer>
  );
};
```

### ObserverGroup

View animation [here](https://teodosii.github.io/react-tweenful/notifications)

Usage of `ObserverGroup` component to watch for mounting and unmounting over a list of notifications

![Notifications](https://github.com/teodosii/react-tweenful/raw/master/gif/notifications.gif "Notifications")

```jsx
<ObserverGroup
  config={{
    duration: 800,
    style: { overflow: 'hidden' },
    mount: { opacity: [0, 1], height: ['0px', 'auto'] },
    unmount: { opacity: [1, 0], height: ['auto', '0px'] },
    easing: 'easeInOutCubic'
  }}
  skipInitial={true}
>
  {this.state.notifications.map(notification => (
    <Notification
      key={notification.id}
      notification={notification}
      onClick={this.removeNotification}
    />
  ))}
</ObserverGroup>
```

### Animate route transition

View animation [here](https://teodosii.github.io/react-tweenful/transition)

Usage of `ObserverGroup` to animate route change

![Routing](https://github.com/teodosii/react-tweenful/raw/master/gif/transition.gif "Routing")

```jsx
import React from 'react';
import { Route, Switch, NavLink } from 'react-router-dom';
import ObserverGroup from 'react-tweenful/ObserverGroup';
import Observer from 'react-tweenful/Observer';

const colors = {
  red: '#EE4266',
  yellow: '#FDB833',
  blue: '#296EB4',
  green: '#0EAD69'
};

class RouteTransitionDemo extends React.Component {
  constructor(props) {
    super(props);
  }

render() {
    const { location } = this.props;

return (
      <div className="route-transition-demo">
        <ul className="nav-links">
          <li><NavLink to="/transition/red">Red</NavLink></li>
          <li><NavLink to="/transition/yellow">Yellow</NavLink></li>
          <li><NavLink to="/transition/blue">Blue</NavLink></li>
          <li><NavLink to="/transition/green">Green</NavLink></li>
        </ul>
        <div className="observer">
          <ObserverGroup>
            <Observer.div
              key={location.pathname}
              className="key-wrapper"
              duration={1000}
              style={{ opacity: 0 }}
              mount={{ opacity: 1 }}
              unmount={{ opacity: 0 }}
              easing={'easeOutQuad'}
            >
              <Switch location={location}>
                <Route exact path={`/transition/red`} component={Red} />
                <Route exact path={`/transition/green`} component={Green} />
                <Route exact path={`/transition/blue`} component={Blue} />
                <Route exact path={`/transition/yellow`} component={Yellow} />
                <Route render={() => <div>Not Found</div>} />
              </Switch>
            </Observer.div>
          </ObserverGroup>
        </div>
      </div>
    );

  );
};

## API

**Update in progress. Stay in touch!**

## Note

A couple of the animations shown here have been initially created for CodePen by other folks. My only contribution to them was to convert them to `react-tweenful` to show real world examples on animating stuff.
