Lottie for Web, Android, iOS, React Native, and Windows

Lottie is a mobile library for Web, and iOS that parses Adobe After Effects animations exported as json with Bodymovin and renders them natively on mobile!

For the first time, designers can create and ship beautiful animations without an engineer painstakingly recreating it by hand. They say a picture is worth 1,000 words so here are 13,000:

How it works

Here's a video tutorial explaining how to export a basic animation and load it in an html page

After Effects

HTML

<script src="js/lottie.js" type="text/javascript"></script>

You can call lottie.loadAnimation() to start an animation. It takes an object as a unique param with:

It returns the animation instance you can control with play, pause, setSpeed, etc.

lottie.loadAnimation({
  container: element, // the dom element that will contain the animation
  renderer: 'svg',
  loop: true,
  autoplay: true,
  path: 'data.json' // the path to the animation json
});

Composition Settings:

Check this wiki page for an explanation for each setting. https://github.com/airbnb/lottie-web/wiki/Composition-Settings

Usage

Animation instances have these main methods:

play


stop


pause


setSpeed(speed)


goToAndStop(value, isFrame)


goToAndPlay(value, isFrame)


setDirection(direction)


playSegments(segments, forceFlag)


setSubframe(useSubFrames)


destroy()


getDuration(inFrames)


Additional methods:


Lottie has several global methods that will affect all animations:

lottie.play() -- with 1 optional parameter name to target a specific animation
lottie.stop() -- with 1 optional parameter name to target a specific animation
lottie.goToAndStop(value, isFrame, name) -- Moves an animation with the specified name playback to the defined time. If name is omitted, moves all animation instances.
lottie.setSpeed() -- first argument speed (1 is normal speed) -- with 1 optional parameter name to target a specific animation
lottie.setDirection() -- first argument direction (1 is normal direction.) -- with 1 optional parameter name to target a specific animation
lottie.searchAnimations() -- looks for elements with class "lottie" or "bodymovin"
lottie.loadAnimation() -- Explained above. returns an animation instance to control individually.
lottie.destroy(name) -- Destroys an animation with the specified name. If name is omitted, destroys all animation instances. The DOM element will be emptied.
lottie.registerAnimation() -- you can register an element directly with registerAnimation. It must have the "data-animation-path" attribute pointing at the data.json url
lottie.getRegisteredAnimations() -- returns all animations instances
lottie.setQuality() -- default 'high', set 'high','medium','low', or a number > 1 to improve player performance. In some animations as low as 2 won't show any difference.
lottie.setLocationHref() -- Sets the relative location from where svg elements with ids are referenced. It's useful when you experience mask issues in Safari.
lottie.freeze() -- Freezes all playing animations or animations that will be loaded
lottie.unfreeze() -- Unfreezes all animations
lottie.inBrowser() -- true if the library is being run in a browser
lottie.resize() -- Resizes all animation instances

Events

you can also use addEventListener with the following events:

Other loading options

lottie.loadAnimation({
  container: element, // the dom element
  renderer: 'svg',
  loop: true,
  autoplay: true,
  animationData: animationData, // the animation data
  // ...or if your animation contains repeaters:
  // animationData: cloneDeep(animationData), // e.g. lodash.clonedeep
  rendererSettings: {
    context: canvasContext, // the canvas context, only support "2d" context
    preserveAspectRatio: 'xMinYMin slice', // Supports the same options as the svg element's preserveAspectRatio property
    title: 'Accessible Title', // Adds SVG title element for accessible animation title
    description: 'Accessible description.', // Adds SVG desc element for accessible long description of animation
    clearCanvas: false,
    progressiveLoad: false, // Boolean, only svg renderer, loads dom elements when needed. Might speed up initialization for large number of elements.
    hideOnTransparent: true, //Boolean, only svg renderer, hides elements when opacity reaches 0 (defaults to true)
    className: 'some-css-class-name',
    id: 'some-id',
  }
});

Doing this you will have to handle the canvas clearing after each frame
Another way to load animations is adding specific attributes to a dom element. You have to include a div and set it's class to "lottie". If you do it before page load, it will automatically search for all tags with the class "lottie". Or you can call lottie.searchAnimations() after page load and it will search all elements with the class "lottie".

Example

 <div style="width:1067px;height:600px"  class="lottie" data-animation-path="animation/" data-anim-loop="true" data-name="ninja"></div>

Preview

You can preview or take an svg snapshot of the animation to use as poster. After you render your animation, you can take a snapshot of any frame in the animation and save it to your disk. I recommend to pass the svg through an svg optimizer like https://jakearchibald.github.io/svgomg/ and play around with their settings.

Recommendations

Files

If you have any images or AI layers that you haven't converted to shapes (I recommend that you convert them, so they get exported as vectors, right click each layer and do: "Create shapes from Vector Layers"), they will be saved to an images folder relative to the destination json folder. Beware not to overwrite an existing folder on that same location.

Performance

This is real time rendering. Although it is pretty optimized, it always helps if you keep your AE project to what is necessary
More optimizations are on their way, but try not to use huge shapes in AE only to mask a small part of it.
Too many nodes will also affect performance.

Help

If you have any animations that don't work or want me to export them, don't hesitate to write.
I'm really interested in seeing what kind of problems the plugin has.

Searching Database…

Что это такое?Lottie-web — это JavaScript-библиотека, которая разбирает анимации Adobe After Effects, экспортированные в JSON с помощью плагина Bodymovin, и отображает их прямо в браузере. Так дизайнеры могут выпускать настоящие анимации без того, чтобы инженер писал их вручную.
Это инструмент для создания анимаций или просто библиотека-проигрыватель?Это только проигрыватель, работающий во время выполнения: анимацию по-прежнему создают в After Effects и экспортируют плагином Bodymovin для AE, а lottie-web лишь отображает экспортированный JSON на вашей странице.
Как добавить это на свою веб-страницу?Подключите сборку lottie.js из build/player/ в свой HTML (или установите через npm/bower), затем вызовите lottie.loadAnimation(), передав элемент-контейнер, рендерер ('svg', 'canvas' или 'html') и либо animationData, либо путь к JSON-файлу.
Нужен ли мне After Effects, чтобы этим пользоваться?Только если вы хотите создавать новые анимации: тогда в After Effects устанавливается расширение Bodymovin для экспорта в JSON. Чтобы просто проигрывать готовые .json-анимации на сайте, достаточно только проигрывателя lottie.js, After Effects не нужен.
Есть ли функции After Effects, которые не экспортируются корректно?Не поддерживаются последовательности изображений, видео и аудиослои, а отрицательное растяжение слоёв ломает экспортированные данные анимации.
Поддерживает ли lottie-web также Android, iOS и React Native?Для этих платформ существуют отдельные нативные библиотеки-проигрыватели Lottie; этот репозиторий — именно веб-рендерер (для браузера) с режимами отрисовки SVG, Canvas и HTML.
Можно ли управлять воспроизведением после загрузки анимации?Да, loadAnimation() возвращает экземпляр с методами play, stop, pause, setSpeed, setDirection, goToAndStop/Play и playSegments для полного контроля над временной шкалой.
Какие рендереры можно выбрать?В параметре renderer при вызове loadAnimation вы выбираете 'svg', 'canvas' или 'html', соотнося точность отображения и производительность.
Где посмотреть примеры анимаций, прежде чем пробовать самому?В README есть ссылки на простое демо и набор примеров анимаций, размещённых на CodePen.
Что будет, если загрузить одни и те же данные анимации дважды?Если в анимации есть repeaters, перед повторным вызовом loadAnimation стоит сделать глубокую копию объекта animationData, так как повторное использование того же объекта может вызвать проблемы.
