# react-component-transition

Easy to use react component to apply animations between component transitions, by using **[Web Animations API](https://developer.mozilla.org/en-US/docs/Web/API/Web_Animations_API)**.

## Demo
**[https://dgpedro.github.io/react-component-transition/](https://dgpedro.github.io/react-component-transition/)**

## Install

```
npm install react-component-transition --save
```

## Typescript

Types are included in the package.

## Goal

The main goal is to provide an easy and fast way to apply simple animations when transitioning from one component to another - without losing too much time testing, adjusting, styling, etc...
In just a couple of lines it's possible to make any react page much more interactive and user friendly.

## Polyfills

Depending on the browser to support, some polyfills might be needed:

- **[Web Animations API](https://developer.mozilla.org/en-US/docs/Web/API/Web_Animations_API/Using_the_Web_Animations_API#browser_support)**
- **[Intersection Observer API](https://developer.mozilla.org/en-US/docs/Web/API/Intersection_Observer_API#browser_compatibility)** (only if `lazy` prop set to `true`)
- **[Promise](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise#browser_compatibility)**

## Usage

### ComponentTransition

```javascript
import { ComponentTransition, AnimationTypes } from "react-component-transition";
const Component = () => {

// ...

return (
        <ComponentTransition
            enterAnimation={AnimationTypes.scale.enter}
            exitAnimation={AnimationTypes.fade.exit}
        >
            {showDetails ? <Details /> : <Summary />}
        </ComponentTransition>
    );
};
```

### Presets

Presets are components that have `enterAnimation` and `exitAnimation` already set, for an easier and cleaner usage.

```javascript
import { Presets } from "react-component-transition";
const Component = () => {
    
    // ...

return (
        <Presets.TransitionFade>
            {show && <Details />}
        </Presets.TransitionFade>
    );
};
```

There's a preset available for each `AnimationTypes`.

### ComponentTransitionList

To be used with lists. Simply return a `ComponentTransition` or any preset in your `map` function and wrap it all with a `ComponentTransitionList`.

```javascript
import { ComponentTransitionList, Presets } from "react-component-transition";
const Component = () => {
    
    // ...

return (
        <ComponentTransitionList>
            {list.map((listItem, index) =>
                <Presets.TransitionScale key={index}>
                    <ListItem {...listItem} />
                </Presets.TransitionScale>
            )}
        </ComponentTransitionList>
    );
};
```
### With react-router

```javascript
import { useLocation } from "react-router-dom";
const AppRoutes = () => {
    const location = useLocation();
    return (
        <ComponentTransition
            enterAnimation={AnimationTypes.slideUp.enter}
            exitAnimation={AnimationTypes.slideDown.exit}
        >
            <Switch key={location.key} location={location}>
                <Route ... />
                <Route ... />
                <Route ... />
            </Switch>
        </ComponentTransition>
    );
};
```

```javascript
import { BrowserRouter } from "react-router-dom";
const App = () => (
    <BrowserRouter>
        <AppRoutes />
    </BrowserRouter>
);
```

### Custom animation

```javascript
import { ComponentTransition, AnimationTypes } from "react-component-transition";
const Component = () => {

// ...

return (
        <ComponentTransition
            enterAnimation={[
                AnimationTypes.slideUp.enter,
                AnimationTypes.fade.enter,
            ]}
            exitAnimation={[{
                keyframes: [
                    { transform: "translate3d(0,0,0)" },
                    { transform: "translate3d(0,50%,0)" },
                    { transform: "translate3d(0,80%,0)" },
                    { transform: "translate3d(0,90%,0)" },
                    { transform: "translate3d(0,100%,0)" },
                ],
                options: {
                    duration: 500,
                    easing: "cubic-bezier(0.83, 0, 0.17, 1)",
                }
            },
            {
                keyframes: [
                    { opacity: 1 },
                    { opacity: 0.3 },
                    { opacity: 0.1 },
                    { opacity: 0 },
                ],
                options: {
                    duration: 300,
                }
            }]
            }
        >
            <Details key={selectedTab} />
        </ComponentTransition>
    );
};
```

## API

### AnimationTypes

`AnimationTypes` are a set of animations already defined that can be used in `enterAnimation` and/or `exitAnimation` props. Availabe ones are:

For each type of `AnimationTypes` there's a respective preset.

### props

All presets and the `ComponentTransition` will wrap their `children` in a `div` element. This `div` is the element that will animate when `children` are unmounting or mounting (it is referenced here as "container").

Name | Type | Default | Description
-----|------|---------|------------
animateContainer | boolean | `false` | if `true` the container will also animate from the exit component size to the enter component size<br />**NOTE:** _All presets have this prop set to `true` by default_
animateContainerDuration | number | 300 | Duration in milliseconds of the container animation
animateContainerEasing | string | "ease" | Easing of container animation
animateOnMount | boolean | `false` | if `true`, applies `enterAnimation` when component mounts in the initial render
className | string | `undefined` | CSS class to set in the container element
classNameEnter | string | `undefined` | CSS class to set in the container element during `enterAnimation`
classNameExit | string | `undefined` | CSS class to set in the container element during `exitAnimation`
disabled | boolean | `false` | disable all animations
enterAnimation | AnimationSettings \| AnimationSettings[] | `undefined` | [Web Animations API parameters](https://developer.mozilla.org/en-US/docs/Web/API/Element/animate#Parameters) to be applied when new component mounts
exitAnimation | AnimationSettings \| AnimationSettings[] | `undefined` | [Web Animations API parameters](https://developer.mozilla.org/en-US/docs/Web/API/Element/animate#Parameters) to be applied when current component will unmount
lazy | boolean | `false` | Will apply `enterAnimation` and `exitAnimation` if the component is visible in the viewport by using the [Intersection Observer API](https://developer.mozilla.org/en-US/docs/Web/API/Intersection_Observer_API). If `true` container element will always be in the DOM
lazyOptions | IntersectionOptions | `undefined` | [Intersection Observer options](https://developer.mozilla.org/en-US/docs/Web/API/Intersection_Observer_API#Intersection_observer_options)
onEnterFinished | () => void | `undefined` | Callback when `enterAnimation` finishes
onExitFinished | () => void | `undefined` | Callback when `exitAnimation` finishes
style | React.CSSProperties | `undefined` | Inline styles to set in the container element
