imgproxy Module

Craft CMS wrapper module for crocodile2u/imgproxy-php, aiming for 1:1 support with Craft’s native Asset transform parameters and making it possible to take advantage of imgproxy-only options.

Setup

Install the Module

composer require mattstein/craft-imgproxy

In config/app.php:

// ...
return [
    // ...
    'modules' => [
        'imgproxy' => modules\imgproxy\Module::class,
    ],
    'bootstrap' => ['imgproxy'],
];

Add Environment Variables

Add the required IMGPROXY_URL and optional IMGPROXY_KEY and IMGPROXY_SALT environment variables for your imgproxy instance.

IMGPROXY_URL=https://my-imgproxy.example
IMGPROXY_KEY=943b421c9eb07c830af81030552c86009268de4e532ba2ee2eab8247c6da0881
IMGPROXY_SALT=520f986b998545b4785e0defbc4f3c1203f22de2374a3d53cb7a7fe9fea309c5

Templating

craft.imgproxy.transform()

Attempts to honor Craft’s transform parameters to generate an imgproxy URL.

Example:

{% set transform = craft.imgproxy.transform(
  asset,
  { width: 300, height: 300, mode: 'crop' }
) %}
{{ tag('img', {
    src: transform.getUrl(),
    alt: asset.alt,
}) }}

craft.imgproxy.srcset()

Generates multiple transform URLs based on the provided sizes array, returning a string ready for an HTML srcset image attribute. (Also follows Craft’s API.)

Example:

{% set transform = craft.imgproxy.transform(
  asset,
  { width: 300, height: 300, mode: 'crop' }
) %}
{{ tag('img', {
    src: transform.getUrl(),
    srcset: transform.srcset(['1x', '2x', '3x']),
    alt: asset.alt,
}) }}

craft.imgproxy.getBuilder()

Returns an instance if imgproxy-php’s UrlBuilder class so you can work with it directly in templates. This exposes the entire API and does not attempt to translate transform parameters from Craft to imgproxy.

{% set url = craft.imgproxy.getBuilder()
    .build(asset.url, asset.width, asset.height)
    .useAdvancedMode()
    .setWidth(200)
    .setHeight(200)
%}

{% do url.options().withRotate(180) %}
{% do url.options().withPixelate(2) %}

{{ tag('img', {
    src: url.toString(),
    alt: '',
}) }}
