API Reference

FlipMove is a React component, and is configured via the following props:

children

Accepted Types: Default Value
Array, Object undefined

The children passed to FlipMove are the component(s) or DOM element(s) that will be moved about. Accepts either a single child (as long as it has a unique key property) or an array of children.

easing

Accepted Types: Default Value
String "ease-in-out"

Any valid CSS3 timing function (eg. "linear", "ease-in", "cubic-bezier(1, 0, 0, 1)").

duration

Accepted Types: Default Value
Number 350

The length, in milliseconds, that the transition ought to take.

delay

Accepted Types: Default Value
Number 0

The length, in milliseconds, to wait before the animation begins.

staggerDurationBy

Accepted Types: Default Value
Number 0

The length, in milliseconds, to be added to the duration of each subsequent element.

For example, if you are animating 4 elements with a duration of 200 and a staggerDurationBy of 20:

  • The first element will take 200ms to transition.
  • The second element will take 220ms to transition.
  • The third element will take 240ms to transition.
  • The fourth element will take 260ms to transition.

This effect is great for "humanizing" transitions and making them feel less robotic.

staggerDelayBy

Accepted Types: Default Value
Number 0

The length, in milliseconds, to be added to the delay of each subsequent element.

For example, if you are animating 4 elements with a delay of 0 and a staggerDelayBy of 20:

  • The first element will start transitioning immediately.
  • The second element will start transitioning after 20ms.
  • The third element will start transitioning after 40ms.
  • The fourth element will start transitioning after 60ms.

Similarly to staggerDurationBy, This effect is great for "humanizing" transitions and making them feel less robotic.

Protip: You can make elements animate one-at-a-time by using an identical duration and staggerDelayBy.

enterAnimation

Accepted Types: Default Value
String, Boolean, Object 'elevator'

Control the onEnter animation that runs when new items are added to the DOM. For examples of this property, see the feature description above.

Accepts several types:

String: You can enter one of the following presets to select that as your enter animation:

  • elevator (default)
  • fade
  • accordionVertical
  • accordionHorizontal
  • none

View the CSS implementation of these presets.

Boolean: You can enter false to disable the enter animation, or true to select the default enter animation (elevator).

Object: For fully granular control, you can pass in an object that contains the styles you'd like to animate.

It requires two keys: from and to. Each key holds an object of CSS properties. You can supply any valid camelCase CSS properties, and flip-move will transition between the two, over the course of the specified duration.

Example:

const customEnterAnimation = {
  from: { transform: 'scale(0.5, 1)' },
  to:   { transform: 'scale(1, 1)' }
};

<FlipMove enterAnimation={customEnterAnimation}>
  {renderChildren()}
</FlipMove>

It is recommended that you stick to hardware-accelerated CSS properties for optimal performance: transform and opacity.

leaveAnimation

Accepted Types: Default Value
String, Boolean, Object 'elevator'

Control the onLeave animation that runs when new items are removed from the DOM. For examples of this property, see the feature description above.

This property functions identically to enterAnimation.

Accepts several types:

String: You can enter one of the following presets to select that as your enter animation:

  • elevator (default)
  • fade
  • accordionVertical
  • accordionHorizontal
  • none

View the CSS implementation of these presets.

Boolean: You can enter false to disable the leave animation, or true to select the default leave animation (elevator).

Object: For fully granular control, you can pass in an object that contains the styles you'd like to animate.

It requires two keys: from and to. Each key holds an object of CSS properties. You can supply any valid camelCase CSS properties, and flip-move will transition between the two, over the course of the specified duration.

Example:

const customLeaveAnimation = {
  from: { transform: 'scale(1, 1)' },
  to:   { transform: 'scale(0.5, 1) translateY(-20px)' }
};

<FlipMove leaveAnimation={customLeaveAnimation}>
  {renderChildren()}
</FlipMove>

It is recommended that you stick to hardware-accelerated CSS properties for optimal performance: transform and opacity.

maintainContainerHeight

Accepted Types: Default Value
Boolean false

Do not collapse container height until after leaving animations complete.

When false, children are immediately removed from the DOM flow as they animate away. Setting this value to true will maintain the height of the container until after their leaving animation completes.

onStart

Accepted Types: Default Value
Function undefined

A callback to be invoked once per child element at the start of the animation.

The callback is invoked with two arguments:

  • childElement: A reference to the React Element being animated.
  • domNode: A reference to the unadulterated DOM node being animated.

In general, it is advisable to ignore the domNode argument and work with the childElement. The domNode is just an escape hatch for doing complex things not otherwise possible.

onFinish

Accepted Types: Default Value
Function undefined

A callback to be invoked once per child element at the end of the animation.

The callback is invoked with two arguments:

  • childElement: A reference to the React Element being animated.
  • domNode: A reference to the unadulterated DOM node being animated.

In general, it is advisable to ignore the domNode argument and work with the childElement. The domNode is just an escape hatch for doing complex things not otherwise possible.

onStartAll

Accepted Types: Default Value
Function undefined

A callback to be invoked once per group at the start of the animation.

The callback is invoked with two arguments:

  • childElements: An array of the references to the React Element(s) being animated.
  • domNodes: An array of the references to the unadulterated DOM node(s) being animated.

These arguments are similar to the ones provided for onStart, except we provide an array of the elements and nodes. The order of both arguments is guaranteed; this means you can use a zipping function like lodash's .zip to get pairs of element/node, if needed.

In general, it is advisable to ignore the domNodes argument and work with the childElements. The domNodes are just an escape hatch for doing complex things not otherwise possible.

onFinishAll

Accepted Types: Default Value
Function undefined

A callback to be invoked once per group at the end of the animation.

The callback is invoked with two arguments:

  • childElements: An array of the references to the React Element(s) being animated.
  • domNodes: An array of the references to the unadulterated DOM node(s) being animated.

These arguments are similar to the ones provided for onFinish, except we provide an array of the elements and nodes. The order of both arguments is guaranteed; this means you can use a zipping function like lodash's .zip to get pairs of element/node, if needed.

In general, it is advisable to ignore the domNodes argument and work with the childElements. The domNodes are just an escape hatch for doing complex things not otherwise possible.

typeName

Accepted Types: Default Value
String 'div'

Flip Move wraps your children in a container element. By default, this element is a div, but you may wish to provide a custom HTML element (for example, if your children are list items, you may wish to set this to ul).

Any valid HTML element type is accepted, but peculiar things may happen if you use an unconventional element.

disableAllAnimations

Accepted Types: Default Value
Boolean false

Sometimes, you may wish to temporarily disable the animations and have the normal behaviour resumed. Setting this flag to true skips all animations.

getPosition

Accepted Types: Default Value
Function getBoundingClientRect

This function is called with a DOM node as the only argument. It should return an object as specified by the getBoundingClientRect() spec.

For normal usage of FlipMove you won't need this. An example of usage is when FlipMove is used in a container that is scaled using CSS. You can correct the values from getBoundingClientRect by using this prop.
