# Component Transition
Configure the component transition animations for when a component is inserted or deleted. This feature takes effect only when [animateTo](ts-explicit-animation.md) is used. The animation duration, curve, and delay are the same as those configured in **animateTo**.
You can configure the component transition animations through the **transition** attribute for when a component is inserted or deleted.

> **NOTE**
>
> 1. When set to a value of the **TransitionOptions** type, the **transition** attribute must work with [animateTo](ts-explicit-animation.md). The animation duration, curve, and delay follow the settings in **animateTo**.
> 2. If the value of the **TransitionOptions** type has only **type** specified, the transition effect will take on the default opacity. For example, **{type: TransitionType.Insert}** produces the same effect as **{type: TransitionType.Insert, opacity: 0}**. If a specific style is specified, the transition effect will not take on the default opacity.
> 3. For details about the scale and rotate effects, see [Transformation](ts-universal-attributes-transformation.md).
## TransitionEffect<sup>10+</sup>
Defines the transition effect by using the provided APIs, as listed below.
| API| Type| Static Function| Description|
| -------- | ---------- | -------- | -------- |
| opacity | number | Yes| Opacity of the component during transition, which is the value of the start point of insertion and the end point of deletion.<br>Value range: [0, 1]<br>**NOTE**<br>A value less than 0 or greater than 1 evaluates to the value **1**.|
| translate | {<br>x? : number \| string,<br>y? : number \| string,<br>z? : number \| string<br>} | Yes| Translation of the component during transition, which is the value of the start point of insertion and the end point of deletion.<br>-**x**: distance to translate along the x-axis.<br>-**y**: distance to translate along the y-axis.<br>-**z**: distance to translate along the z-axis.|
| scale | {<br>x? : number,<br>y? : number,<br>z? : number,<br>centerX? : number \| string,<br>centerY? : number \| string<br>} | Yes| Scaling of the component during transition, which is the value of the start point of insertion and the end point of deletion.<br>- **x**: scale factor along the x-axis.<br>- **y**: scale factor along the y-axis.<br>- **z**: scale factor along the z-axis.<br>- **centerX** and **centerY**: scale center point. The default values are both **"50%"**, indicating that the center point of the page.<br>- If the center point is (0, 0), it refers to the upper left corner of the component.|
| rotate | {<br>x?: number,<br>y?: number,<br>z?: number,<br>angle: number \| string,<br>centerX?: number \| string,<br>centerY?: number \| string<br>} | Yes| Rotation of the component during transition, which is the value of the start point of insertion and the end point of deletion.<br>- **x**: rotation vector along the x-axis.<br>- **y**: Y-component of the rotation vector.<br>- **z**: Z-component of the rotation vector.<br>- **centerX** and **centerY**: rotation center point. The default values are both **"50%"**, indicating that the center point of the page.<br>- If the center point is (0, 0), it refers to the upper left corner of the component.|
| move | [TransitionEdge](ts-appendix-enums.md#transitionedge10) | Yes| Slide-in and slide-out of the component from the screen edge during transition. It is essentially a translation effect, which is the value of the start point of insertion and the end point of deletion.|
| asymmetric | appear: TransitionEffect,<br>disappear: TransitionEffect<br>| Yes| Asymmetric transition effect.<br>The first parameter indicates the transition effect for appearance, and the second parameter indicates the transition effect for disappearance.<br>If the **asymmetric** function is not used for **TransitionEffect**, the transition effect takes effect for both appearance and disappearance of the component.|
| combine | TransitionEffect | No| Combination of transition effects.|
| animation | [AnimateParam](ts-explicit-animation.md#animateparam) | No| Animation settings.<br>The **onFinish** callback in **AnimateParam** does not work here.<br>If **combine** is used for combining transition effects, the animation settings of a transition effect are applicable to the one following it.|
The static functions listed in the preceding table are used to create a **TransitionEffect** object, while the non-static functions apply to the created **TransitionEffect** object.
**TransitionEffect** also provides some static member variables for transition effects:
| Static Member Variable| Description|
| -------- | -------- |
| IDENTITY | Disables the transition effect.|
| OPACITY | Applies a transition effect with the opacity of 0. It is equivalent to **TransitionEffect.opacity(0)**.|
| SLIDE | Applies a transition effect of sliding in from the left when the component appears and sliding out from the right when the component disappears. It is equivalent to **TransitionEffect.asymmetric(TransitionEffect.START, TrasitionEffect.END)**.|
## Example
> **NOTE**
>
> 1. For transition effects combined through the **combine** function, animation settings can be configured through the **animation** parameter on a one-on-one basis. In addition, the animation settings of a transition effect are applicable to the one following it. For example, with **TransitionEffect.OPACITY.animation({duration: 1000}).combine(TransitionEffect.translate({x: 100}))**, the **duration** settings (1000 ms) apply to both the OPACITY and translate effects.
> 2. The animation settings take effect in the following sequence: animation settings specified in the current **TransitionEffect** > animation settings specified in the previous **TransitionEffect** > animation settings specified in **animateTo** that triggers the component to appear and disappear.
> 3. If **animateTo** is not used and **TransitionEffect** does not have the **animation** parameter specified, the component will appear or disappear without any transition animation.
> 4. If the value of an attribute specified in **TransitionEffect** is the same as the default value, no transition animation is applied for the attribute. For example, with **TransitionEffect.opacity(1).animation({duration:1000})**, because the default value of **opacity** is also **1**, no opacity animation will be applied, and the component appears or disappears without any transition animation.
## Example
The following is an example of using **TransitionOptions** for appearance and disappearance of the component.
