ResponsiveImage

Appearance

Cloudinary ​

The image processing capabilities of the Cloudinary image CDN are supported by a helper function provided to you by this library.

Setup ​

Make sure you have the @responsive-image/cdn package installed:

bash
npm install @responsive-image/cdn
bash
yarn add @responsive-image/cdn
bash
pnpm add @responsive-image/cdn

You need to specify the cloudName in your configuration, which you can set up in your application (e.g. app.js):

js
import { setConfig } from '@responsive-image/core';

setConfig('cdn', {
  cloudinary: {
    cloudName: 'my-org',
  },
});

Usage ​

IMPORTANT

Please make sure you have read the section on remote images first.

Use the cloudinary provider function passing the reference to the image on the CDN and optional transformations, and pass the return value to the image component:

gjs
import { ResponsiveImage } from '@responsive-image/ember';
import { cloudinary } from '@responsive-image/cdn';

<template>
  <ResponsiveImage @src={{cloudinary 'path/to/uploaded/image.jpg'}} />
</template>
hbs
<ResponsiveImage
  @src={{responsive-image-cloudinary 'path/to/uploaded/image.jpg'}}
/>
ts
import { LitElement, html } from 'lit';
import { customElement } from 'lit/decorators.js';
import { cloudinary } from '@responsive-image/cdn';
import '@responsive-image/wc';

@customElement('my-app')
export class MyApp extends LitElement {
  render() {
    return html`<responsive-image
      .src=${cloudinary('path/to/uploaded/image.jpg')}
    ></responsive-image>`;
  }
}
tsx
import { ResponsiveImage } from '@responsive-image/react';
import { cloudinary } from '@responsive-image/cdn';

export default function MyApp() {
  return <ResponsiveImage src={cloudinary('path/to/uploaded/image.jpg')} />;
}
tsx
import { ResponsiveImage } from '@responsive-image/solid';
import { cloudinary } from '@responsive-image/cdn';

export default function MyApp() {
  return <ResponsiveImage src={cloudinary('path/to/uploaded/image.jpg')} />;
}
svelte
<script>
  import { ResponsiveImage } from '@responsive-image/svelte';
  import { cloudinary } from '@responsive-image/cdn';
</script>

<ResponsiveImage src={cloudinary('path/to/uploaded/image.jpg')} />

Aspect Ratio ​

For the image component to be able to render width and height attributes to prevent layout shifts after loading has completed, it needs to know the aspect ratio of the source image. Unlike local images it cannot know this upfront for remote images, that's why it is recommended to supply the aspectRatio parameter if possible:

gjs
import { ResponsiveImage } from '@responsive-image/ember';
import { cloudinary } from '@responsive-image/cdn';

<template>
  <ResponsiveImage
    @src={{cloudinary
      '/path/to/image.jpg'
      aspectRatio=1.5
    }}
  />
</template>
hbs
<ResponsiveImage
  @src={{responsive-image-cloudinary '/path/to/image.jpg' aspectRatio=1.5}}
/>
ts
import { LitElement, html } from 'lit';
import { customElement } from 'lit/decorators.js';
import { cloudinary } from '@responsive-image/cdn';
import '@responsive-image/wc';

@customElement('my-app')
export class MyApp extends LitElement {
  render() {
    return html`<responsive-image
      .src=${cloudinary('/path/to/image.jpg', {
        aspectRatio: 1.5,
      })}
    ></responsive-image>`;
  }
}
tsx
import { ResponsiveImage } from '@responsive-image/react';
import { cloudinary } from '@responsive-image/cdn';

export default function MyApp() {
  return (
    <ResponsiveImage
      src={cloudinary('path/to/uploaded/image.jpg', {
        aspectRatio: 1.5,
      })}
    />
  );
}
tsx
import { ResponsiveImage } from '@responsive-image/solid';
import { cloudinary } from '@responsive-image/cdn';

export default function MyApp() {
  return (
    <ResponsiveImage
      src={cloudinary('path/to/uploaded/image.jpg', {
        aspectRatio: 1.5,
      })}
    />
  );
}
svelte
<script>
  import { ResponsiveImage } from '@responsive-image/svelte';
  import { cloudinary } from '@responsive-image/cdn';
</script>

<ResponsiveImage
  src={cloudinary('path/to/uploaded/image.jpg', {
    aspectRatio: 1.5,
  })}
/>

Transformations ​

Besides the transformations that the addon itself implicitly adds (related to resizing images) you can add your own Cloudinary transformations by using the transformations parameter:

gjs
import { ResponsiveImage } from '@responsive-image/ember';
import { cloudinary } from '@responsive-image/cdn';

<template>
  <ResponsiveImage
    @src={{cloudinary
      'path/to/uploaded/image.jpg'
      transformations=(hash co='rgb:20a020' e='colorize:50')
    }}
  />
</template>
hbs
<ResponsiveImage
  @src={{responsive-image-cloudinary
    'path/to/uploaded/image.jpg'
    transformations=(hash co='rgb:20a020' e='colorize:50')
  }}
/>
ts
import { LitElement, html } from 'lit';
import { customElement } from 'lit/decorators.js';
import { cloudinary } from '@responsive-image/cdn';
import '@responsive-image/wc';

@customElement('my-app')
export class MyApp extends LitElement {
  render() {
    return html`<responsive-image
      .src=${cloudinary('path/to/uploaded/image.jpg', {
        co: 'rgb:20a020',
        e: 'colorize:50',
      })}
    ></responsive-image>`;
  }
}
tsx
import { ResponsiveImage } from '@responsive-image/react';
import { cloudinary } from '@responsive-image/cdn';

export default function MyApp() {
  return (
    <ResponsiveImage
      src={cloudinary('path/to/uploaded/image.jpg', {
        co: 'rgb:20a020',
        e: 'colorize:50',
      })}
    />
  );
}
tsx
import { ResponsiveImage } from '@responsive-image/solid';
import { cloudinary } from '@responsive-image/cdn';

export default function MyApp() {
  return (
    <ResponsiveImage
      src={cloudinary('path/to/uploaded/image.jpg', {
        co: 'rgb:20a020',
        e: 'colorize:50',
      })}
    />
  );
}
svelte
<script>
  import { ResponsiveImage } from '@responsive-image/svelte';
  import { cloudinary } from '@responsive-image/cdn';
</script>

<ResponsiveImage
  src={cloudinary('path/to/uploaded/image.jpg', {
    co: 'rgb:20a020',
    e: 'colorize:50',
  })}
/>

It accepts an object of transformations, or an array of objects for chained transformations.

Quality ​

Use the quality parameter to pass a custom quality setting instead of the default auto:

gjs
import { ResponsiveImage } from '@responsive-image/ember';
import { cloudinary } from '@responsive-image/cdn';

<template>
  <ResponsiveImage
    @src={{cloudinary
      'path/to/uploaded/image.jpg'
      quality=50
    }}
  />
</template>
hbs
<ResponsiveImage
  @src={{responsive-image-cloudinary 'path/to/uploaded/image.jpg' quality=50}}
/>
ts
import { LitElement, html } from 'lit';
import { customElement } from 'lit/decorators.js';
import { cloudinary } from '@responsive-image/cdn';
import '@responsive-image/wc';

@customElement('my-app')
export class MyApp extends LitElement {
  render() {
    return html`<responsive-image
      .src=${cloudinary('path/to/uploaded/image.jpg', {
        quality: 50,
      })}
    ></responsive-image>`;
  }
}
tsx
import { ResponsiveImage } from '@responsive-image/react';
import { cloudinary } from '@responsive-image/cdn';

export default function MyApp() {
  return (
    <ResponsiveImage
      src={cloudinary('path/to/uploaded/image.jpg', {
        quality: 50,
      })}
    />
  );
}
tsx
import { ResponsiveImage } from '@responsive-image/solid';
import { cloudinary } from '@responsive-image/cdn';

export default function MyApp() {
  return (
    <ResponsiveImage
      src={cloudinary('path/to/uploaded/image.jpg', {
        quality: 50,
      })}
    />
  );
}
svelte
<script>
  import { ResponsiveImage } from '@responsive-image/svelte';
  import { cloudinary } from '@responsive-image/cdn';
</script>

<ResponsiveImage
  src={cloudinary('path/to/uploaded/image.jpg', {
    quality: 50,
  })}
/>

Image formats ​

By default the component uses the automatic image format selection in Cloudinary.

If you want a picture tag with one or more specific formats as source tags you can specify them using the formats argument:

gjs
import { ResponsiveImage } from '@responsive-image/ember';
import { cloudinary } from '@responsive-image/cdn';

<template>
  <ResponsiveImage
    @src={{cloudinary
      'path/to/uploaded/image.jpg'
      formats=(array 'webp' 'avif')
    }}
  />
</template>
hbs
<ResponsiveImage
  @src={{responsive-image-cloudinary
    'path/to/uploaded/image.jpg'
    formats=(array 'webp' 'avif')
  }}
/>
ts
import { LitElement, html } from 'lit';
import { customElement } from 'lit/decorators.js';
import { cloudinary } from '@responsive-image/cdn';
import '@responsive-image/wc';

@customElement('my-app')
export class MyApp extends LitElement {
  render() {
    return html`<responsive-image
      .src=${cloudinary('path/to/uploaded/image.jpg', {
        formats: ['webp', 'avif'],
      })}
    ></responsive-image>`;
  }
}
tsx
import { ResponsiveImage } from '@responsive-image/react';
import { cloudinary } from '@responsive-image/cdn';

export default function MyApp() {
  return (
    <ResponsiveImage
      src={cloudinary('path/to/uploaded/image.jpg', {
        formats: ['webp', 'avif'],
      })}
    />
  );
}
tsx
import { ResponsiveImage } from '@responsive-image/solid';
import { cloudinary } from '@responsive-image/cdn';

export default function MyApp() {
  return (
    <ResponsiveImage
      src={cloudinary('path/to/uploaded/image.jpg', {
        formats: ['webp', 'avif'],
      })}
    />
  );
}
svelte
<script>
  import { ResponsiveImage } from '@responsive-image/svelte';
  import { cloudinary } from '@responsive-image/cdn';
</script>

<ResponsiveImage
  src={cloudinary('path/to/uploaded/image.jpg', {
    formats: ['webp', 'avif'],
  })}
/>

Remote source ​

The provider supports Cloudinary's fetch mode to automatically fetch images from a remote source and deliver them (with optional custom transformations) through Cloudinary's CDN. Simply pass a fully qualified http(s) URL:

gjs
import { ResponsiveImage } from '@responsive-image/ember';
import { cloudinary } from '@responsive-image/cdn';

<template>
  <ResponsiveImage
    @src={{cloudinary
      'https://upload.wikimedia.org/wikipedia/commons/1/13/Benedict_Cumberbatch_2011.png'
    }}
  />
</template>
hbs
<ResponsiveImage
  @src={{responsive-image-cloudinary
    'https://upload.wikimedia.org/wikipedia/commons/1/13/Benedict_Cumberbatch_2011.png'
  }}
/>
ts
import { LitElement, html } from 'lit';
import { customElement } from 'lit/decorators.js';
import { cloudinary } from '@responsive-image/cdn';
import '@responsive-image/wc';

@customElement('my-app')
export class MyApp extends LitElement {
  render() {
    return html`<responsive-image
      .src=${cloudinary(
        'https://upload.wikimedia.org/wikipedia/commons/1/13/Benedict_Cumberbatch_2011.png',
      )}
    ></responsive-image>`;
  }
}
tsx
import { ResponsiveImage } from '@responsive-image/react';
import { cloudinary } from '@responsive-image/cdn';

export default function MyApp() {
  return (
    <ResponsiveImage
      src={cloudinary(
        'https://upload.wikimedia.org/wikipedia/commons/1/13/Benedict_Cumberbatch_2011.png',
      )}
    />
  );
}
tsx
import { ResponsiveImage } from '@responsive-image/solid';
import { cloudinary } from '@responsive-image/cdn';

export default function MyApp() {
  return (
    <ResponsiveImage
      src={cloudinary(
        'https://upload.wikimedia.org/wikipedia/commons/1/13/Benedict_Cumberbatch_2011.png',
      )}
    />
  );
}
svelte
<script>
  import { ResponsiveImage } from '@responsive-image/svelte';
  import { cloudinary } from '@responsive-image/cdn';
</script>

<ResponsiveImage
  src={cloudinary(
    'https://upload.wikimedia.org/wikipedia/commons/1/13/Benedict_Cumberbatch_2011.png',
  )}
/>
