Installation

Npm

npm install --save vue-silentbox

Import the plugin into Vue:

import { createApp } from 'vue'
import VueSilentbox from 'vue-silentbox'
import 'vue-silentbox/dist/style.css'

createApp({
    // your app props ...
})
.use(VueSilentbox)
.mount('#root')

How to use?

Define an array of images in the data object of your Vue instance or component.

import { createApp } from 'vue'
import VueSilentbox from 'vue-silentbox'
import 'vue-silentbox/dist/style.css'

createApp({
    data: {
        images: [
            {
                src: 'images/image001.jpg',
                srcSet: '/images/image001-640.jpg 640w,/images/image001-1280.jpg 1280w,/images/image001-1920.jpg 1920w',
                description: 'Sunken dreams II. by Arbebuk',
            },
            {
                src: 'images/image002.jpg',
                srcSet: '/images/image002-640.jpg 640w,/images/image002-1280.jpg 1280w,/images/image003-1920.jpg 1920w',
                description: 'Tunnel View Sunrise by Porbital',
            }
        ]
    },
})
.use(VueSilentbox)
.mount('#root')

Then in the template you use a silent-box component to display the gallery.

<silent-box :gallery="images"><!-- your additional content --></silent-box>

Or you can show a single image by just renaming the property.

<silent-box :image="images[0]"><!-- your additional content --></silent-box>

Custom activators

In case you don't like the default image previews that SilentBox provides, you can set your own activators - text, button or even a video! SilentBox provides a named slot for this - silentbox-item. The slot provides variable called silentboxItem which provides you access to all properties you set on image object.

<!--
In this example only alt text is displayed as an activator.
-->
<silent-box :gallery="images">
    <h2 class="tw-text-3xl tw-font-bold tw-mb-2">Gallery</h2>
    <p class="tw-font-light tw-mb-3">
        Items could be merged into groups that make galleries.
    </p>
    <template v-slot:silentbox-item="{ silentboxItem }">
        <p>{{ silentboxItem.alt  }}</p>
    </template>
</silent-box>

Plugin options

You can set the following options to the plugin to change the behaviour of the SilentBox or display additional information.

Name	Required	Type	Default	Description
downloadButtonLabel	no	string	Download	Label used in the download button.

createApp({
    // your app props ...
})
.use(VueSilentbox, {
    downloadButtonLabel: 'Download'
})
.mount('#root')

Image object attributes

You can set the following attributes to the image object to change the behaviour of the SilentBox or display additional information. On the other hand, if you're lazy, only the src attribute is required.

Attribute	required	type	Description
src	yes	string	media source, it could be an image, video or a YouTube / Vimeo embed link
srcSet	no	string	srcSet to make use of responsive images
thumbnail	no	string	image used for thumbnail
thumbnailHeight	no	string	height of the thumbnail in px
thumbnailWidth	no	string	width of the thumbnail in px
description	no	string	short description below image (doesn't work below videos yet)
alt	no	string	alt description for images
autoplay	no	bool	to autoplay youtube / Vimeo video
download	no	bool/string	Link to download the file. When set to a boolean value (true/false), the src is used as the download link.
controls	no	bool	does not work for Vimeo, setting false will hide video controls

Gallery element attributes

These attributes can change the gallery element behaviour.

Attribute	required	type	Description
gallery	no	array	list of image objects that will be displayed in the gallery
image	no	object	image object that will be displayed in the gallery
lazy-loading	no	bool	whether images should be lazy loaded
preview-count	no	number	number of images that should be displayed in the gallery

Events

SilentBox also fires several events that can be further used in your Vue.js application. Each event has a payload that contains the item object which holds information about the currently displayed item.

Event name	When is event fired
silentbox-overlay-opened	when the overlay is opened
silentbox-overlay-hidden	when the overlay is closed (button or ESC key)
silentbox-overlay-next-item-displayed	when the user moves to the next picture (arrow or key)
silentbox-overlay-prev-item-displayed	when the user moves to the previous picture (arrow or key)

Open overlay programatically

SilentBox provides two options how to open the overlay programatically. If you need to open an existing gallery, the best option is to use the ref attribute and then call the method openOverlay on the $refs object in your method. See example:

<silent-box ref="silentbox" :gallery="images"></silent-box>

and then the method openOverlay can be called from your method:

// ...
methods: {
    // the index parameter is optional, however it should be set if you're opening
    // the overlay on different position than the beginning of the gallery
    openOverlayProgramaticallyWithContext (item, index = 0) {
        this.$refs.silentbox.openOverlay(item, index)
    }
}
// ...

However, in case you just want to open an item without any context, it might be a better choice to call the global open method that SilentBox provides.

// ...
methods: {
    openOverlayProgramaticallyWithoutContext (item) {
        this.$silentbox.open(item)
    }
}
// ...

Upgrading from 2.x to 3.x?

Almost all APIs remained same except two things:

• Vue3 always transforms <img /> width and height to numbers, thus properties thumbnailWidth and thumbnailHeight should always be a number
• event fired when user navigates to previous image was renamed to silentbox-overlay-prev-item-displayed from silentbox-overlay-previous-item-displayed

Upgrading from 0.1?

Version 2 brought many breaking changes. There are no more two separate components to display a single image or gallery. So, change all your silentbox-group and silentbox-single components to silent-box. The source of images must be an array of objects or a single object with previously mentioned attributes.
