limit

{{limit data limit}}

Limits the number of items returned from an array; returns a new array.

Parameters

  • data (Array): Collection.
  • limit (Number): Index specifying the number of items to exclude.

Example

Assume that {{cart.items}} returns 10 items. You can use this helper to limit that behavior to only the first four items.

<!-- context = {var: 'This is longer than the chosen limit'} -->
{{limit var 10}}
<!-- => This is lo -->
<!-- context = {var: 'This is longer than the chosen limit'} -->
{{limit var 10}}
<!-- results in: 'This is lo' -->
{{#each (limit cart.items 4)}}
    <li class="previewCartItem">
        <div class="previewCartItem-image">
            {{#if type '==' 'GiftCertificate'}}
                <img src="{{cdn ../../theme_settings.default_image_gift_certificate}}" alt="GiftCertificate" title="GiftCertificate">
            {{else}}
                {{> components/common/responsive-img
                    image=image
                    fallback_size=../../theme_settings.productthumb_size
                    lazyload=../../theme_settings.lazyload_mode
                    default_image=../../theme_settings.default_image_product
                }}
            {{/if}}
        </div>
    </li>
{{/each}}

pluck

{{pluck limit collection path}}

Retrieves corresponding values from some or all elements in a collection using specified search key(s). Returns retrieved values in a comma-separated string. When used in conjunction with the built-in {{each}} helper, returns retrieved values in an array.

Parameters

  • limit, limit-value: Optional parameters to limit the number of results returned.
  • collection (Object|Array): Collection.
  • path (String): The string to search for.

Examples

{{pluck ([limit] <collection> [<limit-value>]) '<path>'}}

If each category in categories contains an image object, use dot notation to access the image's children:

categories: [
    { "id": 1, "name": "Bakeware", "image": { "data": "http://...", "alt": "Bakeware image"} },
    { "id": 2, "name": "Cookware", "image": { "data": "http://...", "alt": "Cookware image"} },
    { "id": 3, "name": "Cutlery", "image": { "data": "http://...", "alt": "Cutlery image"} }
]
{{pluck (limit categories 2) 'image.data'}}
<!-- Returns a comma-separated list of image URLs. -->
users: [
    { "user": "barney", "age": 36, "image": { "url": "barney.jpg" } },
    { "user": "fred",   "age": 40, "image": { "url": "fred.jpg" } }
]
{{pluck users "age"}}
<!-- => 36,40 -->
 
{{pluck users "image.url"}}'
<!-- => barney.jpg,fred.jpg -->
 
Standard pluck helper example:
// {{pluck items "data.title"}}
results in: '["aa", "bb", "cc"]'

cdn

{{cdn assetPath}}

A URL transformer for content delivery networks.

Parameters

  • assetPath (String): Path to the file containing static assets.

Example

{{cdn "assets/img/image.jpg"}}
<!-- => https://cdn.bcapp/3dsf74g/stencil/123/img/image.jpg -->

To reference static assets staged locally outside your <theme-name> directory and uploaded using WebDAV, place the webdav: prefix before each corresponding assetPath parameter. For example, the following link:

<img src="{{cdn 'webdav:img/image.jpg'}}">

will be transformed to a result like this:

<img src="https://cdn.bcapp/3dsf74g/content/img/image.jpg">

In this example, the image.jpg file was uploaded to the WebDAV /content/ directory making /content the WebDAV root directory. Because our presumed local directory is assets/, we can omit that path when referencing its contained files or subdirectories.

CDN custom endpoints

You can define custom CDN endpoints to use with the {{cdn}} helper. By doing so you can include large, high-resolution image assets in themes without exceeding BigCommerce's 50 MB limit when bundling the theme for upload to BigCommerce.

You can also use a local version of the image in development and a remote version on a CDN such as Imgix in production. To do so, define custom CDN endpoints in your theme's config.json file (opens in a new tab).

For example:

{
  "name": "Cornerstone",
  "version": "1.3.5",
  "settings": {
    "homepage_new_products_count": 12,
    "homepage_featured_products_count": 8,
    "cdn": {
      "customcdn": "https://bigcommerce.customcdn.net"
          }
     }
}

After defining the endpoint, you can use the short name in the same way as you use a webdav: protocol:

<img src="{{cdn 'customcdn:img/image.jpg'}}" />

In local development, the helper returns the following:

<img src="/assets/cdn/customcdn/img/image.jpg"/>

In production environment, the helper returns the following:

<img src="https://bigcommerce.customcdn.net/img/image.jpg" />

As highlighted above, the helper is configured to rewrite local URLs to an assets/cdn/ subfolder. The stencil bundle command will exclude this local assets/cdn/ subfolder from the bundle that it creates. This filtering circumvents the 50 MB size limit on the resulting ZIP file.

Early Hint and cdn

Early Hints reduce page load time and perceived latency by allowing browsers to download critical assets earlier in the request lifecycle. For more information, see Early Hint.

Parameters
  • resourceHint - (String)
    • Corresponds to the rel attribute in <link>.
    • Value can be any of preload, preconnect, prerender, dns-prefetch.
    • For more information, see rel (opens in a new tab) on MDN Web Docs.
  • as - (String)

    • Corresponds to the as attribute in <link>.

    • Value can be any of style, font, script, document.

    • If an invalid value is provided, as won't be included.

    • This parameter is optional.

    • For more information, see as (opens in a new tab) on MDN Web Docs.

  • crossorigin - (String)

    • Value can be any of no, anonymous, use-credentials.

    • Defaults to no when no value is provided.

    • This parameter is optional.

    • For more information, see crossorigin (opens in a new tab) on MDN Web Docs.

Example

The following script is an example of Early Hints usage in the Cornerstone theme:

<script async src="{{cdn 'assets/dist/theme-bundle.head_async.js' resourceHint='preload' as='script'}}"></script>

You can view more Early Hints usage in Cornerstone's templates/layout/base.html file by visiting the Cornerstone Repository (opens in a new tab).

EarlyHint

{{ earlyHint '{path}' '{rel}' [as='{script|style|font}'] [crossorigin='{no|anonymous|use-credentials}'] }}

Retrieves the provided URL and produces an early hint to communicate important web page resources. The server indicates which site assets (such as CSS files, JS scripts, and fonts) a browser needs to render a page fully. When used in conjunction with the {{cdn}} helper, load times can improve by 30%.

Parameters

  • path (String): The URL that hosts the resource being hinted.

  • rel (String): Valid arguments are preload, preconnect, prerender, and dns-prefetch.

  • as (String): Optional. Valid arguments are script, style, font.

  • crossorigin (String): Optional. Valid arguments are no (default), anonymous, and use-credentials.

Examples

{{earlyHint 'https://ajax.googleapis.com/ajax/libs/webfont/1.6.26/webfont.js' 'preload' as='script' crossorigin='anonymous'}}

This example produces an early hint in a Link header that looks like:

<https://ajax.googleapis.com/ajax/libs/webfont/1.6.26/webfont.js>; rel=preload; as=script; crossorigin=anonymous

The following example uses the getFontsCollection and stylesheet helpers. These helpers produce early hints by default, without using the earlyHint helper directly.

<script async src="{{cdn 'assets/dist/theme-bundle.head_async.js' resourceHint='preload' as='script'}}"></script>
 
{{getFontsCollection font-display='block'}}
 
<script async src="{{cdn 'assets/dist/theme-bundle.font.js' resourceHint='preload' as='script'}}"></script>
 
{{{stylesheet '/assets/css/theme.css'}}}

The output displays in a Link header that looks like:

Link: <https://cdn.staging.zone/s-cq2iowdr0q/stencil/94e324f0-d179-013b-2a85-0ac13303cc0f/dist/theme-bundle.head_async.js>; rel=preload; as=script; crossorigin=anonymous, 
<https://fonts.googleapis.com/css?family=Montserrat:700,500,400%7CKarla:400&display=block>; rel=preload; as=style, <https://cdn.staging.zone/s-cq2iowdr0q/stencil/94e324f0-d179-013b-2a85-0ac13303cc0f/dist/theme-bundle.font.js>; rel=preload; as=script
<https://cdn.staging.zone/s-cq2iowdr0q/stencil/94e324f0-d179-013b-2a85-0ac13303cc0f/css/theme-6bec0d40-d17a-013b-e9d8-02ea0e5c37ab.css>; rel=preload; as=style

getImageSrcset

{{getImageSrcset stencilImage size}}

The getImageSrcset helper is a replacement for getImage which allows you to generate either a single image URL (for an <img> src) or a list of image sizes for srcset. Using the srcset (opens in a new tab) attribute, you can specify a list of image sizes for the browser to choose from based on the expected size of the image on the page, the device's pixel density, and other factors.

Parameters

  • stencilImage (String): A Stencil image.
  • size (String): A key in the theme_settings object.
  • defaultImage (String): Optional default image URL to use if the stencilImage is undefined.

You can specify what sizes you want as named arguments on the helper.

Example

Default sizes

By specifying use_default_sizes=true on the helper, a srcset string will be constructed with a set of sizes chosen by BigCommerce to be optimal for most uses.

{{getImageSrcset image use_default_sizes=true}}
{{getImageSrcset image "https://place-hold.it/500x300" use_default_sizes=true}}

Default sizes:

'80w': '80w',
'160w': '160w',
'320w': '320w',
'640w': '640w',
'960w': '960w',
'1280w': '1280w',
'1920w': '1920w',
'2560w': '2560w',

Single 1x size

{{getImageSrcset image 1x=theme_settings.zoom_size}}
{{getImageSrcset image 1x="1280x800"}}
{{getImageSrcset image 1x="1280w"}}

By specifying a single size as 1x, you can choose any image resolution. You can reference a value from the theme_settings object (similar to getImage), or you can specify your own size inline. getImageSrcset does not require theme_settings keys to be wrapped in quotes; they should be referenced directly.

Pixel density

{{getImageSrcset image 1x="1280w" 2x="2560w"}}
{{getImageSrcset image 1x="800w" 1.5x="1200w" 2x="1600w"}}
{{getImageSrcset image 1x="640x640" 2x="1280x1280"}}

By specifying several sizes using the pixel density descriptor, you can generate a srcset of different image resolutions for different pixel density screens as described in Resolution switching: Same size, different resolutions (opens in a new tab). For example, you can specify a 2x image for Retina screens, and a 1x image for normal screens.

By specifying several sizes using the inherent width descriptor, you can generate a srcset of different image resolutions based on width, which can in turn be selected by the browser based on the expected size of the image when the page is painted. It is recommended to use this together with a sizes attribute on the <img> element as described in Resolution switching: Different sizes (opens in a new tab). In Cornerstone, this is handled automatically via JavaScript.

As above, you can reference theme_settings keys or specify your own size inline.

any

{{any arg}}

Renders block if one or more parameters are true.

Parameters

  • arg (String|Number|Array|Object)

Example

{{#any items selected=true}}
  <!-- block to display if any items have selected=true -->
{{/any}}

A usage example is templates/components/category/shop-by-price.html (opens in a new tab), a category page in Stencil's Cornerstone base theme that does not have faceted search turned on. Shoppers will see Shop by price filters instead of product filters.

In this component, the {{any}} helper is used to determine whether a shopper has selected one of the filters, and whether a "reset" button needs to be displayed:

{{#any shop_by_price selected=true}}
    <li class="navList-item">
        <a href="{{category_url}}" class="navList-action">
            {{lang 'category.reset'}}
        </a>
    </li>
{{/any}}

all

{{all arg}}

Renders block if all parameters are true.

Parameters

  • arg (String|Number|Array|Object)

Example

{{#all items theme_settings.optionA theme_settings.optionB}}
   <!-- block to display if all items evaluate to true -->
{{/all}}
{{#all product.custom_fields theme_settings.show_custom_fields_tabs}}
    <li class="tab">
        <a class="tab-title" href="#tab-{{dashcase (lowercase (sanitize theme_settings.pdp-custom-fields-tab-label))}}">{{sanitize theme_settings.pdp-custom-fields-tab-label}}</a>
    </li>
{{/all}}

compare

{{compare a operator b}}

Compares values with JavaScript operators. Renders block if comparison of the first and third parameters returns true.

Parameters

contains

{{contains collection value}}

Renders block if collection has the given value, using strict equality (===) for comparison, otherwise the inverse block is rendered (if specified). If a startIndex is specified and is negative, it is used as the offset from the end of the collection.

Parameters

  • collection (Array|Object|String): The collection to iterate over.
  • value (String|Number|Array|Object): The value to check for.

Example

<!-- array = ['a', 'b', 'c'] -->
{{#contains array "d"}}
  This will not be rendered.
{{else}}
  This will be rendered.
{{/contains}}

for

{{for a b}}

Repeats block for a specified range from index a to index b. To protect against infinite loops, this helper is limited to 100 iterations.

Parameters

  • a (Number): Starting number.
  • b (Number): Ending number. (Inclusive)

Example

{{#for 1 12}}
    {{lang (concat 'common.short_months.' $index)}}
{{/for}}

if

{{if arg}}

Renders if block when if-statement evaluates to true; otherwise renders else block.

Parameters

  • arg (String|Number|Array|Object)

Example

{{#if page_type '===' 'account_order'}}
    <li class="navBar-item is-active">
        <a class="navBar-action" href="{{urls.account.orders.all}}">{{lang 'account.nav.orders'}}</a>
    </li>
{{else}}
    <li class="navBar-item is-active">{{lang 'account.nav.orders'}}</li>
{{/if}}

or

{{or arg}}

Renders block if one or more parameters evaluates to true.

Parameters

  • arg (String|Number|Array|Object): Parameters can be of mixed types.

Example

{{#or 1 0 0 0 0 0 0}}
<!-- 1 evaluates to true, so block is rendered-->
{{/or}}
{{#or options configurable_fields}}
    <a href="#" data-item-edit="{{id}}">{{lang 'cart.checkout.change'}}</a>
{{/or}}

unless

{{unless arg}}

Renders a block if a statement is false; does not support operators for comparison expressions.

Parameters

  • arg (String|Number|Array|Object)

Example

{{#each category_results}}
<li class="category-suggestion">
    {{#each this}}
        <a href="{{url}}">{{name}}</a>

Example

{{#get "posts" blog}}{{/get}}

getObject

{{#with (getObject "a.b.c" someObject)}}...{{/with}}

Use property paths (a.b.c) to get an object from the context. Differs from the get helper in that this helper will return the actual object including the given property key. This helper does not work as a block helper.
