🔮refr
- Performance: It's the fastest way to animate in React. It doesn't have to go through the React reconciler.
- Familiar: It's a hook, so you can use it in any function component.
- Simple: It's just a single function that you can call from anywhere.
- Predictable: You can cancel your animation at any time and it will run at 60fps.
- Composable: You can use it in conjunction with the state hook to create animations.
- Extensible: You can write your own hooks that depend on it.
- Flexible: You can use it to schedule updates or to set timeouts.
It's just a single function that you can call from anywhere. It's a hook that will run on every frame and give you the time delta. If you return true
it will keep running, otherwise it will cancel.
You can also use it to set timeouts that will run on the next frame. This is useful when you want to force an update after a state change.
