Custom Cursor using Framer Motion

Custom Cursor using Framer Motion

In this article I will demonstrate, how to make a custom cursor using Framer Motion, React.

This will be a short article since this is a fairly straightforward thing to do.

Libraries Used

  • Framer Motion: A motion animation library that works perfectly with ReactJS

Project Setup

  • Setup a Barebones React/NextJS project using any template. I'll be using NextJS with Typescript and TailwindCSS, which at the time of writing is the default NextJS template.

  • Install Framer motion library

npm install framer-motion

Refer to the Framer Motion Docs for any issues

  • Remove the boilerplate code if needed. I'm adding cursor-none to hide the default cursor across our app.
export default function Home() {
  return (
    <main className="flex cursor-none min-h-screen flex-col items-center justify-center">
    </main>
  );
}

Adding the Framer Motion Component

  • Create a separate component labeled CustomCursor.tsx and add it to the required entry point in the project.

      "use client";
    
      import { motion } from "framer-motion";
      import { useEffect, useState } from "react";
      import React from "react";
    
      export const CustomCursor = () => {
        return (
            <motion.div
              className="fixed h-8 w-8 pointer-events-none rounded-full"
            ></motion.div>
        );
      };
    
  • Now this motion.div component will be our new cursor. The div component offered by Framer Motion has props that let us animate, translate, and implement actions based on user events.

  • So we will use the props, animate & variants

  • The animate prop is used to pass

    • An object containing different values, that need to be animated

    • Active variant: A variant is also a set of values that need to be animated

  • But the difference between the two is that in case we have multiple different states that need to be animated for different scenarios then instead of having multiple if else and separate logic functions we can have different variants.

  • In this case, we pass an object which has all the different variants defined, and the animate prop will then be used to pass the active variants. This might still need logic functions but it will be easier to understand and update.

  • <motion.div
            className="sm:visible fixed h-12 w-12 pointer-events-none rounded-full"
            animate={{
              backgroundColor: "transparent",
              border: "1px solid #08080D",
              borderColor: "#F0F9F6",
            }}
          ></motion.div>
    
  • But this does not make our element move according to the cursor. So we will add an event listener, that listens to the 'mousemove' event inside a useEffect hook.

  • This event listener will save the position of the mouse cursor variable that can be inside a state variable

const [mousePosition, setMousePosition] = useState({
    x: 0,
    y: 0,
  });

  useEffect(() => {
    const onMouseMove = (e: any) => {
      setMousePosition({
        x: e.clientX,
        y: e.clientY,
      });
    };

    window.addEventListener("mousemove", onMouseMove);

    return () => {
      window.removeEventListener("mousemove", onMouseMove);
    };
  }, []);
  • The animate prop accepts the x, and y coordinates of the element, so on each update of the coordinates, it will be animated.

  • Now the stored cursor position will be passed to the motion.div element through the animation prop

animate={{
          x: mousePosition.x - 24,
          y: mousePosition.y - 24,
          backgroundColor: "transparent",
          border: "10px solid red",
        }}
  • Here the x, and y coordinates are subtracted by 2* height/width of the element respectively since the element's top left pixel will align with the cursor and not the center of the element which will give trouble while clicking if the cursor is invisible. Or you can keep it like that if you want a challenge ;)

  • Now there is also a transition prop that can be used to alter the animation duration, transition style and other properties.

transition={{ duration: 2, type: "spring", stiffness: 100, mass: 0.1 }}
  • And that's it. You can now change the style of the custom cursor element however you want and use it as your cursor.

  •   "use client";
    
      import { motion } from "framer-motion";
      import { useEffect, useState } from "react";
      import React from "react";
    
      export const CustomCursor = () => {
        const [mousePosition, setMousePosition] = useState({
          x: 0,
          y: 0,
        });
    
        useEffect(() => {
          const mouseMove = (e: any) => {
            setMousePosition({
              x: e.clientX,
              y: e.clientY,
            });
          };
    
          window.addEventListener("mousemove", mouseMove);
    
          return () => {
            window.removeEventListener("mousemove", mouseMove);
          };
        }, []);
        return (
          <motion.div
            transition={{ duration: 2, type: "spring", stiffness: 100, mass: 0.1 }}
            className="sm:visible fixed h-12 w-12 top-0 left-0 pointer-events-none rounded-full"
            animate={{
              x: mousePosition.x - 24,
              y: mousePosition.y - 24,
              backgroundColor: "transparent",
              border: "10px solid red",
            }}
          ></motion.div>
        );
      };
