Magnetic Hover Vue3

[Nekuso]

Hi, I'm trying to make a magnetic hover composable in Vue3, GSAP and I wanted to replicate from this Link 2 Ways to Make a Magnetic Buttons using React, GSAP, Framer Motion (olivierlarose.com) . I'm needing help how to convert it with typscript too.

Here is what I have so far :

import { ref, watchEffect } from 'vue'
import gsap from 'gsap'

export function MagneticHover({ children:any }) {
  const magnetic = ref(null)

  watchEffect(() => {
    const xTo = gsap.quickTo(magnetic.value.current, 'x', {
      duration: 1,
      ease: 'elastic.out(1, 0.3)'
    })
    const yTo = gsap.quickTo(magnetic.value.current, 'y', {
      duration: 1,
      ease: 'elastic.out(1, 0.3)'
    })

    magnetic.value.current.addEventListener('mousemove', (e) => {
      const { clientX, clientY } = e
      const { height, width, left, top } = magnetic.value.current.getBoundingClientRect()
      const x = clientX - (left + width / 2)
      const y = clientY - (top + height / 2)

      xTo(x)
      yTo(y)
    })

    magnetic.value.current.addEventListener('mouseleave', (e) => {
      xTo(0)
      yTo(0)
    })
  })

  return () => {
    return children({ ref: magnetic })
  }
}

 

[GSAP Helper]

It's pretty tough to troubleshoot without a minimal demo - the issue could be caused by CSS, markup, a third party library, your browser, an external script that's totally unrelated to GSAP, etc. Would you please provide a very simple CodePen or Stackblitz that demonstrates the issue? 

 

Please don't include your whole project. Just some colored <div> elements and the GSAP code is best. See if you can recreate the issue with as few dependancies as possible. If not, incrementally add code bit by bit until it breaks. Usually people solve their own issues during this process! If not, then at least we have a reduced test case which greatly increases your chances of getting a relevant answer.

 

Here's a starter CodePen that loads all the plugins. Just click "fork" at the bottom right and make your minimal demo: 

See the Pen aYYOdN by GreenSock (@GreenSock) on CodePen

 

Using a framework/library like React, Vue, Next, etc.? 

CodePen isn't always ideal for these tools, so here are some Stackblitz starter templates that you can fork and import the gsap-trial NPM package for using any of the bonus plugins: 

• React (please read this article!)
• Next
• Svelte
• Sveltekit
• Vue
• Nuxt

 

Please share the StackBlitz link directly to the file in question (where you've put the GSAP code) so we don't need to hunt through all the files. 

 

Once we see an isolated demo, we'll do our best to jump in and help with your GSAP-specific questions.
