  1. Selecting a list-item works but doesn’t animate, because GSAP thinks that div._selected has left the DOM as onLeave() indicates. It’s still there, but in a new position. The beforeUpdate() and updated() lifecycle hooks are where I'm getting the state and performing the flip. As an aside, the animation works correctly when the List.vue data changes. 🤷‍♂️ Any idea how to approach this? --- Places.vue <template> <list> <list-item class="place" v-for="place in places" :key="place.id" @click="selectPlace(place)" :selected="place.id === $store.state.places.selected_record_id"> <div class="name">{{ place.name }}</div> </list-item> </list> </template> <script> export default { name: 'places-page', methods: { selectRecord ({ id }) { this.selected_record = id; } } } </script> ListItem.vue <template> <li class="_item" @click="$emit('click')"> <slot></slot> <!-- This is what moves around --> <div class="_selected" data-flip-id="selected" v-if="selected"> </div> </li> </template> <script> export default { name: 'list-item', props: { selected: { type: Boolean, default: false } } } </script> List.vue <template> <ul class="list-control"> <slot></slot> </ul> </template> <script> export default { name: 'list-control', data () { return { state: null }; }, beforeUpdate () { this.$data.state = Flip.getState(gsap.utils.toArray('.list-control [data-flip-id]')); }, updated () { Flip.from(this.$data.state, { duration: 0.8, ease: 'expo.out', simple: true, nested: true, onEnter: elements => { console.log('*** onEnter', elements); }, // When clicking on an item, this thinks that `div._selected` // has left the DOM and didn’t come back. Seems like // a race condition, but unsure how to proceed since the DOM // should be fully `updated` at this point onLeave: elements => { console.log('*** onLeave', elements); } }); } } </script>
  2. Banging my head a bit. I've got a few Scroll Trigger based animations on the home page of a site and it works flawlessly when in local development. It isn't until we've deployed to a production/staging environment does it break. Effectively what's happening is when we load the site on production/staging all animations run immediately. Not sure if its a component mounting issue (which would mean its not a GSAP issue) or if something is being compiled/computed differently in a live environment? Each section is setup as follows: 1. Define the animation/scroll trigger in the `mount` lifecycle hook 2. Use `$refs` to pass elements into the animation. <template> <div id="vid-container" class="h-screen w-screen bg-white"> <video @loadeddata="loaded" class="w-full fixed inset-0 duration-500 transition-opacity opacity-0" :class="{'opacity-100': videoLoaded}" src="https://player.vimeo.com/external/611257045.hd.mp4?s=785a9d52ed5d188f762436b1bb618493f784d3f5&profile_id=174" autoplay loop muted preload></video> <svg ref="mask" class="mask absolute w-full h-full" > <mask id="mask"> <rect width="100%" height="100%" fill="white"></rect> <text font-family="Bagnard, serif" font-weight="500" x="50%" y="49%" class="origin-center " text-anchor="middle" transform="scale(15)" > <tspan x="50%">Freelance</tspan> <tspan x="50%" dy="1em">Founders</tspan> <tspan style="font-size: .5rem" x="50%" dy="2em"> ↓ </tspan> </text> </mask> <rect id="bg" width="100%" height="100%" fill="#fff"></rect> </svg> </div> </template> <script> import { gsap } from "gsap"; import { ScrollTrigger } from "gsap/ScrollTrigger"; import { CSSRulePlugin } from "gsap/CSSRulePlugin"; if (process.client) { gsap.registerPlugin(ScrollTrigger, CSSRulePlugin); } export default { data() { return { videoLoaded: false, } }, mounted() { console.log('hero mounted') let width = window.innerWidth let speed = 350 //pixels per second let endX = width let duration = endX / speed let ease = "sine.inOut" let intro = ''; if (this.$refs.mask) { this.$nextTick(() => { intro = gsap.timeline({ onComplete: () => {}, scrollTrigger:{ trigger: this.$refs.mask, start: "bottom 100%", end: "bottom 50%", pin: true, scrub: true } }); intro.to(this.$refs.mask, { scale: 5, opacity: 0, duration: 5, ease: ease }, 'intro') } ) } }, methods: { loaded() { this.videoLoaded = true; } } } </script> Staging link example: https://freelance-founders-hgc9zjyrf-progresslabs.vercel.app/ FYI - Working on a minimal example to post here shortly.
  3. Hello, I'm really worried by a problem i have for a gsap scrollTrigger animation i try to implement in a nested Nuxt component. When previewing with markers activated, it appears that the start and end of the trigger are fixed, and not at all near the designated div. Sorry for the tailwind flood in the code - I've already successfully made gsap scrolltrigger animations with tailwind, but it was not in a nested component. I use GSAP with CDN, and scrolltrigger was doing well on other projects. My hypothesis is that the problem is related to a mounting + viewport-height + nested component stuff, but I'm stil lnew to this and i can't understand the problem. In this example, I use refs, but I've already tried a thousand times with a class trigger too (for example, <div class="trigger">) <template> <div ref="trigger" class='w-full h-screen text-black justify-center flex-1 align-middle my-auto relative p-4 pr-8 flex flex-grow bg-white box-border z-5'> <div class="relative flex h-full w-full flex-col"> <div class="flex h-full w-full shadow-inner bg-mastro2 absolute z-5 bg-cover bg-top">huh ?</div> </div> <div ref="carte" class="absolute overflow-scroll flex h-screen justify-end ml-auto "> <div class='p-5 rounded-xl bg-white bg-opacity-70 my-auto mr-10 z-6 flex flex-col w-1/2 justify-center'> <div class='loader_title font-display mb-4 text-gray-700 text-left leading-none text-5xl'>Votre point de départ idéal pour la Côte d'Azur.</div> <div class='loader_legend font-sans text justify'>Lorem ipsum dolor sit amet consectetur adipisicing elit. Titae facere, voluptate vero ea a eius. .</div> <div class='loader_button mt-4 '><button @click="carta()" class="bg-opacity-50 hover:bg-opacity-100 border border-black p-3 w-32 text-center outline-none text-black bg-white">RESERVER</button></div> </div> </div> </div> </template> <script> export default { mounted() { const { trigger, carte } = this.$refs let hero_scroll = gsap.timeline({ scrollTrigger: { trigger: trigger, start: 'top center', end: 'bottom center', markers:true, scrub: true, } }) .to(carte, { x: -200, duration:3 }).reverse() }} </script>
  4. It appears as though the scrollerProxy is initiated multiple times after routing which causes the matrix 3d animation to jump from -232213 to 0 and back. I think this is because the nuxt instance is kept while routing between pages that also use the _.vue page template but I cant figure out how to force it to forget the past scrollerProxy 😢 Any advice as to how to initiate smoothscrolling in Nuxt? // _.vue template <template> <div> </div> </template> <script> import { gsap } from 'gsap' import { ScrollTrigger } from 'gsap/ScrollTrigger' gsap.registerPlugin(ScrollTrigger) export default { mounted() { this.smooth() this.$forceUpdate() }, destroyed() { // used to kill the ScrollTrigger instance for this component this.expand = false }, methods: { smooth() { if (process.client) { window.scrollTo(0,0) const locoScroll = new this.LocomotiveScroll({ el: document.querySelector('.smooth-scroll'), smooth: true }) // each time Locomotive Scroll updates, tell ScrollTrigger to update too (sync positioning) locoScroll.on('scroll', ScrollTrigger.update) ScrollTrigger.scrollerProxy('.smooth-scroll', { scrollTop(value) { return arguments.length ? locoScroll.scrollTo(value, 0, 0) : locoScroll.scroll.instance.scroll.y }, // we don't have to define a scrollLeft because we're only scrolling vertically. getBoundingClientRect() { return {top: 0, left: 0, width: window.innerWidth, height: window.innerHeight} }, // LocomotiveScroll handles things completely differently on mobile devices - it doesn't even transform the container at all! So to get the correct behavior and avoid jitters, we should pin things with position: fixed on mobile. We sense it by checking to see if there's a transform applied to the container (the LocomotiveScroll-controlled element). pinType: document.querySelector('.smooth-scroll').style.transform ? 'transform' : 'fixed' }) // each time the window updates, we should refresh ScrollTrigger and then update LocomotiveScroll. ScrollTrigger.addEventListener('refresh', () => locoScroll.update()) // after everything is set up, refresh() ScrollTrigger and update LocomotiveScroll because padding may have been added for pinning, etc. ScrollTrigger.refresh() const headerItems = ['.header__logo', '.nav', '.header__trigger'] if (!this.isTouchDevice()) { headerItems.forEach((item) => { gsap.to(item, { scrollTrigger: { trigger: '.header', scroller: '.smooth-scroll', scrub: true, pin: true, start: 'top', end: document.querySelector('body').offsetHeight, pinSpacing: false, }, y: document.querySelector('body').offsetHeight, transformOrigin: 'center top', ease: 'none' }) }) const largeMedia = document.querySelectorAll('.large-media.no-controls') if (largeMedia) { largeMedia.forEach((media) => { let mediaItem = media.querySelector('video') if (media.querySelector('img')) { mediaItem = media.querySelector('img') } gsap.to(mediaItem, { scrollTrigger: { trigger: media, scroller: '.smooth-scroll', scrub: true, start: 'top', end: 'bottom', }, y: '100%', transformOrigin: 'center top', ease: 'none' }) }) } const nextCase = document.querySelector('.next-case') if (nextCase) { gsap.to('.next-case .large-media', { scale: 1, opacity: 0, scrollTrigger: { trigger: nextCase, scroller: '.smooth-scroll', start: `top-=${window.innerHeight / 2}`, end: `bottom-=${window.innerHeight}`, scrub: 1, } }) gsap.to('.next-case__background', { opacity: 1, scrollTrigger: { trigger: nextCase, scroller: '.smooth-scroll', start: `top-=${window.innerHeight / 2}`, end: `bottom-=${window.innerHeight}`, scrub: 1, } }) gsap.to('.large-text-header', { opacity: 1, scrollTrigger: { trigger: nextCase, scroller: '.smooth-scroll', start: `top-=${window.innerHeight / 2}`, end: `bottom-=${window.innerHeight}`, scrub: 1, } }) const observerTrigger = document.querySelector('.next-case__observer-trigger') const onIntersection = (entries) => { for (const entry of entries) { if (entry.isIntersecting) { this.loaded = entry.intersectionRatio if (entry.intersectionRatio > 0.95) { this.background = true if (!this.expand) { // window.location.href = nextCase.querySelector('a').getAttribute('href') // goor, doch effectief this.$router.push(nextCase.querySelector('a').getAttribute('href')) this.expand = true } } } } } let threshold = [] // create array with numbers between 0 and 1 for (var i = 0; i <= 100; i++) { threshold.push(i / 100) } const observer = new IntersectionObserver(onIntersection, { threshold }) observer.observe(observerTrigger) } } } }, isTouchDevice() { try { document.createEvent('TouchEvent') return true } catch (e) { return false } } }, } </script>
  5. Hi people, Anybody have problem with Nuxt, Vuetify and ScrollTrigger - wrong start position for trigger? Start is set to "top top" but with markers: true I see that start is above trigger div element with a value that depends on width of page. As trigger div element is positioned lower on page, gap is getting bigger. Same code works fine in Vue. Even most simple ScrollTriger example behaves same in Nuxt - start is above trigger element (if trigger div is in the middle of page, not top). I think that this probelm have something to do with Nuxt server side rendering, but not sure. I tried to wrap everything in if (process.client) { ... } but no success. Anybody have similar problems or idea? Thanks, gmilic
  6. Hi again. I'm having an issue I can't seem to go around... In Nuxt, I'm using ScrollTrigger.create to pin to specified panels on a index.vue page. All is fine. When navigating to other pages (with or without ScrollTriger animations), the new page is still running the ScrollTrigger, thus pinning to the index.vue instructions, even though its a totally diferent page. My initial thought was to do 'ScrollTrigger.kill()' on the lifecycle 'beforeDestroy()', which works... until I come back to the index page to see there's no animation anymore... I can't do it in codepen (don't know how to do Nuxt there), but I've prepared a codesandbox.io. https://codesandbox.io/s/unruffled-antonelli-dl8fw In summary: If I don't do ScrollTrigger.kill(), the next pages still run to the current ScrollTrigger animation (next pages become unusable) If I do ScrollTrigger.kill() when the current page is destroyed, the next pages are correct. But when navigating again to the initial one, there's no more animation. Any ideas?
  7. Sorry for the noob question here, but I can't seem find it anywhere, so here goes. My nuxt.js index page has several 'panel' components. Each one is full page, and are animated like on this codepen. https://codepen.io/urbgimtam/pen/XWXdypQ Because I'm working with Nuxt, on the main page (responsible for animating the 'panels') I'm using something like: <template> <div> <panel :content="content_a" /> <panel :content="content_b" /> <panel :content="content_c" /> </div> </template> <script> import { gsap, ScrollTrigger } from 'gsap/all' import panel from '[path/to/component]' export default { components: { panel }, data() { return { tl = gsap.timeline() } }, mounted() { gsap.registerPlugin(ScrollTrigger) [... animations defined here ] }, methods: { playAnim() { this.tl.play(0) } } } </script> However, inside each <panel>, I also want to have independent animations. If inside a <panel> component I have again <script> import {gsap, ScrollTrigger} from 'gsap/all export default { data() { panelTimeline: gsap.timeline() }, mounted() { gsap.registerPlugin(ScrollTrigger) [... animations defined here] }, methods: { playAnim() { this.panelTimeline.play(0) } } } </script> is the panelTimeline refering to the same timeline as the parent? I seem to have some interference somewhere in my project and I'm wondering if the parent component ends up sharing the same timeline as the children. I'm using ScrollTrigger on the index (which is the parent of all the panel components), and I've read on the Docs that it uses one single timeline. If so, what should be the best way to make sure to have independent timelines? Big thank you in advance. PS: On gsap v.2, we would do tl: new Timeline() and that would work (and there was no ScrollTrigger )
  8. Hello everyone, i just started using the Club Greensock Plugins with Nuxt.js and quickly faced the problem of importing them using the ES6 import syntax. I have tried multiple methods to get it working, but all i get is the error "Cannot read property 'middleware' of undefined" after importing it in my component with "import 'gsap/DrawSVGPlugin'". Importing TimelineMax works. The same happens when using a private git repo like described here: All the files from the Club Download's "bonus-files-for-npm-users" folder are in the root of the gsap package downloaded from npm, with a custom package.json like described in the post above. Thanks in advance
  9. Hi, is there a way to use the gsap Draggable in Nuxt.js? I get the error "navigator is not defined" in file "node_modules\gsap\Draggable.js" line 391 _isIE10orBelow = (((/MSIE ([0-9]{1,}[\.0-9]{0,})/).exec(navigator.userAgent) || (/Trident\/.*rv:([0-9]{1,}[\.0-9]{0,})/).exec(navigator.userAgent)) && parseFloat( RegExp.$1 ) < 11), //Ideally we'd avoid user agent sniffing, but there doesn't seem to be a way to feature-detect and sense a border-related bug that only affects IE10 and IE9. I am referencing gsap and Draggable inside my .vue file by: import TweenMax from 'gsap' import Draggable from 'gsap/Draggable' I am guessing this is due to Nuxt doing a server side render and not having a window/navigator object?
  10. Hi, all. When I try to import the DrawSVGPlugin to a NuxtJS project, I get the following error: TypeError: Cannot read property 'defaultView' of undefined at /Users/mdf/Sites/nuxtproject/node_modules/gsap/DrawSVGPlugin.js:19:27 at Object.<anonymous> (/Users/mdf/Sites/nuxtproject/node_modules/gsap/DrawSVGPlugin.js:202:54) at Module._compile (module.js:569:30) at Object.Module._extensions..js (module.js:580:10) at Module.load (module.js:503:32) at tryModuleLoad (module.js:466:12) at Function.Module._load (module.js:458:3) at Module.require (module.js:513:17) at require (internal/module.js:11:18) at r (/Users/mdf/Sites/nuxtproject/node_modules/vue-server-renderer/build.js:5812:16) at Object.<anonymous> (webpack:/external "gsap/DrawSVGPlugin":1:0) at __webpack_require__ (webpack:/webpack/bootstrap 8aad739dc52752aa5015:25:0) at Object.70 (2.server-bundle.js:123:77) at __webpack_require__ (webpack:/webpack/bootstrap 8aad739dc52752aa5015:25:0) at Object.61 (pages/index.vue:7:0) at __webpack_require__ (webpack:/webpack/bootstrap 8aad739dc52752aa5015:25:0) The error is related to the call to `_doc.defaultView` and only happens when the page is server rendered, not when it is client rendered. I'm not sure if there is an issue with the vue-server-renderer package or if I'm not importing the plugin correctly. I've tried importing the plugin from the assets folder import TweenLite from 'gsap'; import '~/assets/DrawSVGPlugin'; as well as copying it into the gsap folder in node_modules import TweenLite from 'gsap'; import 'gsap/DrawSVGPlugin'; Both produce the same error. The error is also not Nuxt-specific but happens whenever Vue server-side rendering is used. I put together a bare-bones example to illustrate the problem here https://github.com/michaeldfoley/vue-ssr-drawsvgplugin-error. Any help would be appreciated.
