Initialize Swiper

Now, when we have Swiper's HTML, we need to initialize it using the following function:

new Swiper(swiperContainer, parameters) - initialize swiper with options

For example:

var mySwiper = new Swiper('.swiper-container', {
    speed: 400,
    spaceBetween: 100
});   

Swiper Parameters

Let's look on list of all available parameters:

Parameter Type Default Description
initialSlide number 0 Index number of initial slide.
direction string 'horizontal' Could be 'horizontal' or 'vertical' (for vertical slider).
speed number 300 Duration of transition between slides (in ms)
setWrapperSize boolean false Enabled this option and plugin will set width/height on swiper wrapper equal to total size of all slides. Mostly should be used as compatibility fallback option for browser that don't support flexbox layout well
virtualTranslate boolean false Enabled this option and swiper will be operated as usual except it will not move, real translate values on wrapper will not be set. Useful when you may need to create custom slide transition
width number Swiper width (in px). Parameter allows to force Swiper width. Useful only if you initialize Swiper when it is hidden.
Setting this parameter will make Swiper not responsive
height number Swiper height (in px). Parameter allows to force Swiper height. Useful only if you initialize Swiper when it is hidden.
Setting this parameter will make Swiper not responsive
autoHeight boolean false Set to true and slider wrapper will adopt its height to the height of the currently active slide
roundLengths boolean false Set to true to round values of slides width and height to prevent blurry texts on usual resolution screens (if you have such)
nested boolean false Set to true on nested Swiper for correct touch events interception. Use only on nested swipers that use same direction as the parent one
Autoplay
autoplay number -

Delay between transitions (in ms). If this parameter is not specified, auto play will be disabled

If you need to specify different delay for specifi slides you can do it by using data-swiper-autoplay (in ms) attribute on slide:

<!-- hold this slide for 2 seconds -->
<div class="swiper-slide" data-swiper-autoplay="2000">
autoplayStopOnLast boolean false Enable this parameter and autoplay will be stopped when it reaches last slide (has no effect in loop mode)
autoplayDisableOnInteraction boolean true Set to false and autoplay will not be disabled after user interactions (swipes), it will be restarted every time after interaction
Progress
watchSlidesProgress boolean false Enable this feature to calculate each slides progress
watchSlidesVisibility boolean false watchSlidesProgress should be enabled. Enable this option and slides that are in viewport will have additional visible class
Freemode
freeMode boolean false If true then slides will not have fixed positions
freeModeMomentum boolean true If true, then slide will keep moving for a while after you release it
freeModeMomentumRatio number 1 Higher value produces larger momentum distance after you release slider
freeModeMomentumVelocityRatio number 1 Higher value produces larger momentum velocity after you release slider
freeModeMomentumBounce boolean true Set to false if you want to disable momentum bounce in free mode
freeModeMomentumBounceRatio number 1 Higher value produces larger momentum bounce effect
freeModeMinimumVelocity number 0.02 Minimum touchmove-velocity required to trigger free mode momentum
freeModeSticky boolean false Set to true to enable snap to slides positions in free mode
Effects
effect string 'slide' Could be "slide", "fade", "cube", "coverflow" or "flip"
fade object
fade: {
  crossFade: false
}
Fade effect parameters
cube object
cube: {
  slideShadows: true,
  shadow: true,
  shadowOffset: 20,
  shadowScale: 0.94
}
Cube effect parameters. For better performance you may disable shadows
coverflow object
coverflow: {
  rotate: 50,
  stretch: 0,
  depth: 100,
  modifier: 1,
  slideShadows : true
}
Coverflow effect parameters. For better performance you may disable shadows
flip object
flip: {
  slideShadows : true
  limitRotation: true
}
Flip effect parameters. limitRotation (when enabled) limits slides rotation angle to 180deg maximum. It allows to quickly "flip" between different slides. If you use "slow" transitions then it is better to disable it.
Parallax
parallax boolean false Enable, if you want to use "parallaxed" elements inside of slider
Slides grid
spaceBetween number 0 Distance between slides in px.
slidesPerView number or 'auto' 1

Number of slides per view (slides visible at the same time on slider's container).

If you use it with "auto" value and along with loop: true then you need to specify loopedSlides parameter with amount of slides to loop (duplicate)

slidesPerView: 'auto' is currently not compatible with multirow mode, when slidesPerColumn > 1

slidesPerColumn number 1 Number of slides per column, for multirow layout
slidesPerColumnFill string 'column' Could be 'column' or 'row'. Defines how slides should fill rows, by column or by row

observeParents boolean false Set to true if you also need to watch Mutations for Swiper parent elements
Breakpoints
breakpoints object Allows to set different parameter for different responsive breakpoints (screen sizes). Not all parameters can be changed in breakpoints, only those which are not required different layout and logic, like slidesPerView, slidesPerGroup, spaceBetween. Such parameters like slidesPerColumn, loop, direction, effect won't work. For example:
var swiper = new Swiper('.swiper-container', {
  // Default parameters
  slidesPerView: 4,
  spaceBetween: 40,
  // Responsive breakpoints
  breakpoints: {
    // when window width is <= 320px

Hash Navigation

Hash navigation is intended to have a link to specific slide that allows to load page with specific slide opened.

To make it work, you need to enable it by passing hashnav:true parameter and adding slides hashes in data-hash attribute:

<div class="swiper-container">
    <div class="swiper-wrapper">
        <div class="swiper-slide" data-hash="slide1">Slide 1</div>
        <div class="swiper-slide" data-hash="slide2">Slide 2</div>
        <div class="swiper-slide" data-hash="slide3">Slide 3</div>
        <div class="swiper-slide" data-hash="slide4">Slide 4</div>
        <div class="swiper-slide" data-hash="slide5">Slide 5</div>
        ...
    </div>
</div>
var swiper = new Swiper('.swiper-container', {
  //enable hash navigation
  hashnav: true
})

Parallax

Since version 3.0.3 Swiper supports parallax transition effects for swiper/slides nested elements. There are two types of parallax elements supported:

To enable parallax effects you need to init Swiper with passed parallax:true parameter and add data-swiper-parallax attribute on required elements

<div class="swiper-container">
    <!-- Parallax background element -->
    <div 
        class="parallax-bg" 
        style="background-image:url(http://lorempixel.com/900/600/nightlife/2/)" 
        data-swiper-parallax="-23%">
    </div>
    <div class="swiper-wrapper">
        <div class="swiper-slide">
            <!-- Each slide has parallax title -->
            <div class="title" data-swiper-parallax="-100">Slide 1</div>
            <!-- Parallax subtitle -->
            <div class="subtitle" data-swiper-parallax="-200">Subtitle</div>
            <!-- And parallax text with custom transition duration -->
            <div class="text" data-swiper-parallax="-300" data-swiper-parallax-duration="600">
              <p>Lorem ipsum dolor sit amet, ...</p>
            </div>
        </div>
        ...
    </div>
</div>

All elements with specified data-swiper-parallax attribute will have parallax transition. This attribute may accept:

It is possible to overwrite parallax direction by using data-swiper-parallax-x and data-swiper-parallax-y attributes with same rules

You can also pass custom transition duration for parallax elements by adding data-swiper-parallax-duration attribute.

Lazy Loading

To enable lazy loading, first of all we need special layout for images or elements with backround in slides:

<div class="swiper-container">
    <div class="swiper-wrapper">
 
        <!-- Lazy image -->
        <div class="swiper-slide">
            <img data-src="path/to/picture-1.jpg" class="swiper-lazy">
            <div class="swiper-lazy-preloader"></div>
        </div>
 
        <!-- Lazy image with srscet-->
        <div class="swiper-slide">
            <img data-src="path/to/logo-small.png" data-srcset="path/logo/logo-large.png 2x" class="swiper-lazy">
            <div class="swiper-lazy-preloader"></div>
        </div>
 
        <!-- Element with lazy background image -->
        <div class="swiper-slide">
            <div data-background="path/to/picture-2.jpg" class="swiper-lazy">
                <div class="swiper-lazy-preloader"></div>
            </div>
        </div>
 
        <!-- Lazy background image on slide itself -->
        <div data-background="path/to/picture-3.jpg" class="swiper-slide swiper-lazy">
            <div class="swiper-lazy-preloader"></div>
        </div>
    </div>
</div> 

As you see:

You may also add animated preloader spinner to slide which will be removed automatically after image loaded:

<div class="swiper-lazy-preloader"></div>

Or white-one for dark layout:

<div class="swiper-lazy-preloader swiper-lazy-preloader-white"></div>

After that we need to enable lazy loading on Swiper initialization:

var swiper = new Swiper('.swiper-container', {
    // Disable preloading of all images
    preloadImages: false,
    // Enable lazy loading
    lazyLoading: true
});    

If you use slidesPerView "auto" or slidesPerView > 1, then you should also enable watchSlidesVisibility and Swiper will load images in currently visible slides

Zoom

Swiper supports zoom images functionality (similar to what you see on iOS when browsing single photo) where you can zoom-in image by pinch gesture and or by zoom-in/out by double tap on it. In this case, additional layout is required:

<div class="swiper-container">
    <div class="swiper-wrapper">
        <div class="swiper-side">
            <div class="swiper-zoom-container">
                <img src="path/to/image1.jpg">
            </div>
        </div>
        <div class="swiper-side">
            <div class="swiper-zoom-container">
                <img src="path/to/image2.jpg">
            </div>
        </div>
        <div class="swiper-side">Plain slide with text</div>
        <div class="swiper-side">
            <!-- Override maxZoom parameter -->
            <div class="swiper-zoom-container" data-swiper-zoom="5">
                <img src="path/to/image1.jpg">
            </div>
        </div>
    </div>
</div>

All "zoomable" images should be wrapped with the div with swiper-zoom-container class. Note, it doesn't support to zoom anything else except single image.

You can override maxZoom parameter for specific slides by using data-swiper-zoom attribute on zoom container.

Emitter API / Events

Emitter API allows to you add events/callbacks to Swiper like usual events, even after Swiper initialization:

// Init Swiper
var mySwiper = new Swiper('.swiper-container');
 
// Later add callback
mySwiper.on('slideChangeStart', function () {
    console.log('slide change start');
});
 
// Add one more handler for this event
mySwiper.on('slideChangeStart', function () {
    console.log('slide change start 2');
});
 
// Add handler that will be executed only once
mySwiper.once('sliderMove', function () {
    console.log('slider moved');
});
 
// Somewhen later, remove all slideChangeStart handlers
mySwiper.off('slideChangeStart');  

Note, that callback/event name in this case is the same as usual callback name but without "on" and with lowercase first character, so "onTouchMove" becames just "touchMove"

Access to Swiper's Instance

If you initialize Swiper using HTML it is still possible to access to Swiper's instance. It is swiper property of Swiper's HTML container element:

var mySwiper = $('.swiper-container')[0].swiper;
 
// Now you can use all slider methods like
mySwiper.slideNext();

Custom Build

Since version 3.4.0 Swiper comes with Gulp builder that allows to build custom library version where you may include only required modules. We need the following:

  1. Download and unzip Swiper GitHub repository to local folder
  2. Install Node.js (if not installed)
  3. Install Gulp (if not installed) by executing the following command in terminal:
    $ npm install --global gulp
  4. Now, we need to install required dependencies. Go to the folder with downloaded and unzipped Swiper repository and execute in terminal:
    $ npm install
  5. Now, we are ready to build custom version of Framework7. We need to execute gulp custom command and pass components/modules that we want to include as argument. For example, if we want to include just Accordion and Tabs:
    $ gulp custom -zoom,lazy-loading,effects
    Note, that there shouldn't be spaces between comma and components name
  6. That is all. Now you should see new custom/ folder that will contain custom JS and CSS files and their minified versions

Following modules are available:
