Visol.Neos.ResponsiveImages
===========================

[](#visolneosresponsiveimages)

This Neos package helps using npm's lazysizes strategy to implement responsive images. See

Installation
------------

[](#installation)

To install the package correctly, go to your theme package (e.g. `Packages/Sites/Visol.Site`) and run the following command:

```
composer require visol/neos-responsiveimages --no-update

```

- Install lazysizes. E.g. with npm

    ```
    npm install lazysizes --save

    ```
- Add the JavaScript sources to your main script

    ```
    import 'lazysizes/plugins/parent-fit/ls.parent-fit.min';
    import 'lazysizes/plugins/bgset/ls.bgset.min';
    import 'lazysizes/lazysizes.min';

    ```

Quick Start
-----------

[](#quick-start)

Just replace usages of the `Neos.Fusion:Image` prototype with `Visol.Neos.ResponsiveImages:ImageTag`. e.g.

```
image = Visol.Neos.ResponsiveImages:ImageTag {
    asset = ${q(event).property('teaserImage')}
    ratio = 1.46
}

```

Or use the ViewHelper provided. e.g.

```
{namespace responsiveImages=Visol\Neos\ResponsiveImages\ViewHelpers}

```

Configuration
-------------

[](#configuration)

Adjust the desired image sizes in your `Settings.yaml`

```
Visol:
  Neos:
    ResponsiveImages:
      SizesPresets:
        Default:
          - 16
          - 48
          - 96
          - 160
          - 320
          - 480
          - 640
          - 960
          - 1024
          - 1440
          - 1920
          - 2560
          - 3840
          - 5120

```

Usage with background images
----------------------------

[](#usage-with-background-images)

Use `Visol.Neos.ResponsiveImages:SrcSet` prototype to generate srcset-Attribute

```
imageUri = Visol.Neos.ResponsiveImages:SrcSet {
    asset = ${q(offer).property('image')}
    ratio = 0.91
}

```

Add class `lazyload` and data-attributes

```

```
