Framer Motion 🤝 Theatre

Seamlessly integrate Theatre.js with Framer Motion and React and get the best of Theatre.js' editing tools and Framer Motion's declarative API. Animate Framer Motion's motion values using Theatre.js, with all the complex stuff like sheets, objects, animation instancing and wiring taken care of. Plus you automatically get visual selection tools when in dev mode.

Why?

While Theatre.js' concepts can be a bit hard to wrap your head around, its terminology maps surprisingly well to React and Framer Motion concepts.

• Sheets -> React components
• Sheet instances -> React component instances
• Objects -> Framer Motion motion values

By enforcing this interpretation, we can wrap Theatre.js' complexity in a simple declarative API that is very easy to read and write.

Features

• Use Theatre.js with a simple declarative API.
• Animate Framer Motion's motion values using Theatre.js.
• Automatically creates and manages sheet objects and sheet instances.
• Hold down the Alt key to display selectable objects in dev mode.

Installation

yarn add framer-motion-theatre framer-motion @theatre/core @theatre/studio

Usage

The following example demonstrates how to use Framer Motion Theatre. A working version can be found in the src directory.

const project = getProject("framer-motion-theatre", { state: theatreState });

function App() {
  return (
    // Wrap your components in TheatreProvider, passing the project.
    // Optionally, pass in studio, or 'auto' if you want it set up automatically in development
    // Caveat: 'auto' relies on your bundler being smart enough to tree-shake,
    // check the console when running the production bundle.
    <TheatreProvider project={project} studio="auto">
      <div className="container">
        {/* Pass your components a unique animation ID besides the regular props. */}
        <Box animationId="Box 1" color="#E493B3" />
        <Box animationId="Box 2" color="#EEA5A6" />
      </div>
    </TheatreProvider>
  );
}

// All components using framer-motion-theatre hooks must be directly wrapped in withTheatre. Other than that, they are regular React components.
const Box = withTheatre("Box", ({ color }: { color: string }) => {
  // useSheetObject returns an object of motion values you can plug into motion.* elements.
  const div = useSheetObject("div", {
    width: 100,
    height: 100,
    scale: types.number(1, { nudgeMultiplier: 0.01 }),
    borderRadius: types.number(0, {
      nudgeMultiplier: 0.1,
      range: [0, Infinity],
    }),
    skewX: 0,
  });

  const text = useSheetObject("text", {
    content: "Click me!",
    y: 0,
  });

  // useControls returns the controls associated with this animation instance.
  const controls = useControls();

  return (
    <motion.div
      // Besides the motion values, useSheetObject also returns a function to enable selection tools for this element.
      ref={div.$studio.setSelectionTarget}
      onClick={() => {
        controls.position = 0;
        controls.play({ rate: 0.8 });
      }}
      style={{
        // Being an object of motion values, you can even directly destructure it onto the style prop.
        ...div,
        backgroundColor: color,
        color: "white",
        fontWeight: "bold",
        display: "flex",
        justifyContent: "center",
        alignItems: "center",
      }}
    >
      <motion.span ref={text.$studio.setSelectionTarget} style={{ ...text }}>
        {/* You can also keyframe text by directly passing it as children. */}
        {text.content}
      </motion.span>
    </motion.div>
  );
});

API

TheatreProvider

Wrap your app in TheatreProvider, passing it your Theatre.js project. Optionally, pass in studio, or 'auto' if you want it set up automatically in development. Caveat: 'auto' relies on your bundler being smart enough to tree-shake, check the console when running the production bundle.

<TheatreProvider project={project} studio="auto">
  <App />
</TheatreProvider>

withTheatre

Wrap your components in withTheatre to gain access to Framer Motion Theatre hooks and automatically set up sheets and objects for that component.

const MyComponent = withTheatre("MyComponent", () => {
  // Your component here
});

useSheetObject

Animate motion values using Theatre.js. Returns an object of motion values you can plug into motion.* elements. Accepts an object of Theatre.js' prop types.

const div = useSheetObject("div", {
  width: 100,
  height: 100,
  scale: types.number(1, { nudgeMultiplier: 0.01 }),
});

useControls

Returns the controls associated with this animation instance. Learn more about Theatre.js' animation controls here.

const controls = useControls();

controls.play();

useTheatre

Returns the project and the studio instance associated with the component.

const { project, studio } = useTheatre();

useEffect(() => {
  project.ready.then(() => {
    // ...
  });
}, [project]);
