Meteor Transitions

Easy to use CSS3 transitions for use in MeteorJS.

Demo: http://transitions-demo.meteor.com

Demo Repository: https://github.com/jamielob/transitions-demo

Getting started

Add the transitions package to you your project:

meteor add jamielob:transitions

Only 3 things are needed to make transitions work.

A container div
A content div
Choosing the animations you want to use for the in and out transitions

Full page transitions using iron-router

After adding and setting up the iron-router package, wrap your {{>yield}} in a <div> with a class of transitions-container. If you want the container to be full screen then you'll need to add height: 100%; to the container.

<template name="yourLayoutTemplate">
  <div class="transitions-container" style="height:100%;">
    {{>yield}}
  </div>
</template>

Next, wrap your content on each template in a <div> with a class of transitions-content.

<template name="page">
     <div class="transitions-content">
        <a href="https://github.com/jamielob/transitions/blob/master/{{pathFor 'anotherPage'}}" data-transition-out="slideLeftOut" data-transition-in="slideLeftIn">Go to another page</a>
     </div>
</template>

Pick the in and out transition animations you want and set them on the link or button, using data-transition-in and data-transition-out.

Inline transitions using dynamic templates

Wrap your dynamic template in a <div> with a class of transitions-container.

  <div class="transitions-container">
    {{> UI.dynamic template=dynamicTemplate}}
  </div>

Next, wrap your content on each template in a <div> with a class of transitions-content.

<template name="dynamic1">
     <div class="transitions-content">
        Some content
     </div>
</template>

Now, each time you switch the value of dynamicTemplate, the content with transition with the animation of your choice. If you are triggering the change via a button or link, you can put the data-transition-in and data-transition-out on there as in the iron:router example. Or you can set a default animation for all transitions to use.

Configuration (Optional)

You can set the classes of the container and content to whatever you want like this:

Transitions.container = '.custom-container';
Transitions.content = '.custom-content';

You can set up default transitions so that all of your links will use. For example:

Transitions.transitionIn = 'slideLeftIn';
Transitions.transitionOut = 'slideLeftOut';

Available Transitions

Build the transition name using the options below. For example, slideUpIn and slideUpOut are valid tansition names.

slide - Up | Down | Left | Right - Out | In
slideFade - Up | Down | Left | Right - Out | In
scale - Out | In
pivot - Up | Down | Left | Right - Out | In
flip - Up | Down | Left | Right - Out | In
fall
spin - Left | Right - Out | In
fold - Up | Down | Left | Right - Out | In
hinge - Top | Bottom | Left | Right - Out | In
room - Up | Down | Left | Right - Out | In
cube - Up | Down | Left | Right - Out | In
swing - Up | Down | Left | Right - Out | In
sweep - Up | Down | Left | Right - Out | In

Additional Classes

onTop: Ensures that the transition remains on top. Needed for some transition combinations. For example, you might decide to use roomUpIn and onTop together like so - data-transition-in="roomUpIn onTop"

delay100: Delays the transition from started for set time in ms. Available in 100 increments up to 1000. For example - data-transition-in="sweepUpIn delay500"

Reacting when a transition is completed

When the transition is completed, a data-transition-done event is triggered. You can capture it as shown below.

$(document).on("data-transition-done", function() {
  console.log("transition-done received")
});

A simple example code that sets an onRendered callback which will change the background-color right after the transition is completed can be done as follows.

Template.onRendered(function() {

  var _dependency = new Tracker.Dependency();

  Tracker.autorun(function() {
    _dependency.depend();
    $('h1').first().css('background-color','green');
  });

  $(document).on("data-transition-done", function() {
    _dependency.changed();
  });

});

Jade Compatibility

By default this package doesnt support jade completely. You can however use a combination of jade and HTML Templates. You just have to make sure that your main transitions-container div is inside an HTML template, and then you can use Jade templates for all of your other templates. Here is a simple example:

layout.html:

<template name="layout">  
    <div class="transitions-container" style="height:100%">
        {{> yield}}
    </div>
</template>

home.tpl.jade (which uses the layout template above):

.transitions-content    
        a.home-menu-link(href="https://github.com/jamielob/transitions/blob/master/{{pathFor 'page2'}}" data-transition-out="slideFadeLeftOut" data-transition-in="slideFadeRightIn") page2

See this issue for more details.

Known Issues / To Do

Sweep seems to need delay100 or above to work consistently on iPhone (as in demo).
