Animation » The Transition Property

The Transition Property

With the animate property, you define which properties should animate and to what value. How things should move — what you might call the ‘animation options’ — those you set with another property, transition.

An easing curve

When you move, rotate, or resize a frame or motion element (animating physical properties), it will, by default, happen with a spring animation. However, you can select a different type. Here I picked one of the easing curves: "anticipate".

export function An_easing_curve(Component): ComponentType {
    return (props) => {
        return (
            <Component
                {...props}
                animate={{ rotate: 45, scale: 1.5 }}
                transition={{ ease: "anticipate", duration: 2 }}
            />
        )
    }
}
B01 – An easing curve

It lets the frame move back a little — in anticipation of what’s about to happen.

Easing curves like this one (called tween curves) can also have a duration. I picked 2 seconds. When you omit duration, you’ll get the default value: 0.3 seconds.

Spring settings

Let’s go back to that default spring. You can adjust a bunch of its settings; one of them is the spring’s damping ratio. The lower the value (the default is 10), the more it will oscillate. Here I changed it to 3:

export function Spring_settings(Component): ComponentType {
    return (props) => {
        return (
            <Component
                {...props}
                animate={{ scale: 1.5 }}
                transition={{ type: "spring", damping: 3 }}
            />
        )
    }
}

Repeat and delay

Add a repeat value to make an animation run more than once. For instance, with a repeat of 2, the animation will run three times (two extra after the initial one).

Or you set it to Infinity and have it repeat till the end of time (or until you close the preview, whichever comes first).

export function Repeat_after_delay(Component): ComponentType {
    return (props) => {
        return (
            <Component
                {...props}
                animate={{ rotate: 360 }}
                transition={{
                    ease: "linear",
                    duration: 2,
                    repeat: Infinity,
                    delay: 1,
                }}
            />
        )
    }
}
B03 – Repeat after a delay

With delay, you add a pause before the start of the animation (also in seconds). It will only delay the beginning of the initial animation; and not insert pauses between the repetitions.

I gave this animation a "linear" easing to get a steady rotation at a constant speed.

delay, repeat

Delay between repetitions

You can also add a pause between the repetitions of a repeat, with another setting: repeatDelay.

With the below override, the frame will wait 1 second between every 2-second rotation:

export function Delay_between_repetitions(Component): ComponentType {
    return (props) => {
        return (
            <Component
                {...props}
                animate={{ rotate: 360 }}
                transition={{
                    duration: 2,
                    repeat: Infinity,
                    delay: 1,
                    repeatDelay: 1,
                }}
            />
        )
    }
}
B04 – Delay between repetitions

repeatDelay works with all three repeat types (more about those next).

Repeat type and Bézier curves

Your animation can repeat in a few different ways. The default repeatType (used in the former examples) is "loop": the animation will just start over. The other two, "mirror" and "reverse", make it go back and forth.

Repeat types
"loop"The default type. The animation simply runs again.
"mirror"Flips the from and to values. The animation runs forward, backward, then forward again, etc. (This was called flip in earlier versions.)
"reverse"Does the same but also reverses the animation curve. So when the animation starts slowly, the reverse animation will end slowly. (Earlier, this was called yoyo.)

"reverse" was called yoyo previously, which was fitting, as you can see in this example:

export function Reverse_with_Bezier(Component): ComponentType {
    return (props) => {
        const { style, ...rest } = props

        return (
            <Component
                {...rest}
                style={{ ...style, y: -90 }}
                animate={{ y: 70, rotate: 360 }}
                transition={{
                    delay: 1,
                    duration: 2,
                    ease: [0.075, 0.82, 0.165, 1],
                    repeat: Infinity,
                    repeatType: "reverse",
                }}
            />
        )
    }
}

Bézier curves

Typically, you give ease one of the (11) predefined easing curves, like "anticipate", "easeOut", or "linear". But you can also give it an array with the four numbers that define a Bézier curve.

In this example, I used a stronger ease-out ([0.075, 0.82, 0.165, 1]) to make the yo-yo effect even more noticeable.

Repeating spring animations

Since the change to this new repeatType syntax (in Framer Motion 2.5), you can also repeat spring animations.

Matt Perry posted this project as an example:

export default function App() {
    return (
        <motion.div
            className="handle"
            initial={{ x: -200 }}
            animate={{ x: 200 }}
            transition={{
                type: "spring",
                repeat: Infinity,
                repeatType: "mirror",
                repeatDelay: 0.1
            }}
        />
    );
}

Transition settings per property

The transition property is a bit like the animation options you could give a layer in Classic: it defines how all the frame’s properties will animate. However, you can override that global setting and provide distinct values for one or more properties, like here for rotate:

Example 1

export function Separate_transition_values_1(Component): ComponentType {
    return (props) => {
        const { style, ...rest } = props

        return (
            <Component
                {...rest}
                style={{ ...style, y: -90 }}
                animate={{
                    y: 70,
                    rotate: 360,
                }}
                transition={{
                    delay: 1,
                    duration: 2,
                    ease: [0.075, 0.82, 0.165, 1],
                    repeat: Infinity,
                    repeatType: "reverse",
                    rotate: {
                        delay: 1,
                        duration: 2,
                        ease: "linear",
                        repeat: Infinity,
                    },
                }}
            />
        )
    }
}
B06 – Separate transition values 1

When defining separate transition settings for a property, the global values will be ignored. That’s why the rotate animation now defaults back to a repeat type of "loop" (and also why we need to give it the same 1-second delay and 2-second duration).

Example 2

In this second example, I added a spring animation to a smaller scale of 0.8. Again, the globally set values are ignored (repeat, repeatType, …), so this scale animation runs just once.

export function Separate_transition_values_2(Component): ComponentType {
    return (props) => {
        const { style, ...rest } = props

        return (
            <Component
                {...rest}
                style={{ ...style, y: -90 }}
                animate={{
                    y: 70,
                    rotate: 360,
                    scale: 0.8,
                }}
                transition={{
                    delay: 1,
                    duration: 2,
                    ease: [0.075, 0.82, 0.165, 1],
                    repeat: Infinity,
                    repeatType: "reverse",
                    rotate: {
                        delay: 1,
                        duration: 2,
                        ease: "linear",
                        repeat: Infinity,
                    },
                    scale: { delay: 1, type: "spring", damping: 3 },
                }}
            />
        )
    }
}
