Why?
This plugin detects the width of any image container as well as the device pixel ratio
density to load the optimal image size needed.
Images are resized on-the-fly via the Cloudimage service, thus offering a comprehensive
automated image optimization service.
When an image is first loaded on your website or mobile app,
Cloudimage's resizing servers will download the origin image from
the source, resize it for the client's screen size and deliver to your users through one or multiple
Content Delivery Networks (CDNs). The generated image formats are cached in the CDN and will be delivered rocket fast on any subsequent request.
**NOTE:** Your original (master) images have to be stored on a server
or storage bucket (S3, Google Cloud, Azure Blob...) reachable over
HTTP or HTTPS by Cloudimage. If you want to upload your master images to
Cloudimage, contact us at
[[email protected]](mailto:[email protected]).

To see the Cloudimage Responsive plugin in action, please check out the
[Demo page](https://scaleflex.github.io/next-cloudimage-responsive/).
Play with your browser's window size and observe your
Inspector's Network tab to see how Cloudimage delivers the optimal
image size to your browser, hence accelerating the overall page
loading time.

To use the Cloudimage Responsive plugin, you will need a
Cloudimage token to deliver your images over CDN. Don't worry, it only takes seconds to get one by
registering [here](https://www.cloudimage.io/en/register_page).
Once your token is created, you can configure it as described below.
This token allows you to use 25GB of image cache and 25GB of worldwide
CDN traffic per month for free.
using npm
```
$ npm install next-cloudimage-responsive
```
using yarn
```
$ yarn add next-cloudimage-responsive
```
After installing the next-cloudimage-responsive lib, simply initialize it with your **token** and the **baseURL**
of your image storage with **CloudimageProvider** and wrap your application with **CloudimageProvider**:
```jsx
import { CloudimageProvider } from 'next-cloudimage-responsive';
function MyApp({ Component, pageProps }) {
const cloudimageConfig = {
token: 'demo',
baseURL: 'https://cdn.scaleflex.it/demo/'
};
return (
);
}
export default MyApp;
```
### Img component:
```jsx
import { Img } from 'next-cloudimage-responsive';
```
### BackgroundImg component:
```jsx
import { BackgroundImg } from 'next-cloudimage-responsive';
{'Your content...'}
```
### token
###### Type: **String** | Default: **"demo"** | _required_
Your Cloudimage customer token.
[Subscribe](https://www.cloudimage.io/en/register_page) for a
Cloudimage account to get one. The subscription takes less than a
minute and is totally free.
### customDomain
###### Type: **String** | Default: **"cloudimage.io"** | _optional_
If you use a custom CNAME for your cloudimage integration, you can set it here.
Note: this will disregard your token above as this should be built into the CNAME entry.
### baseURL
###### Type: **String** | Default: **""** | _optional_
Your image folder on server, this alows to shorten your origin image URLs.
### apiVersion
###### Type: **String** |Default: **'v7'** | _optional_
Allow to use a specific version of API.
- set a specific version of API
```javascript
const cloudimageConfig = {
token: 'demo',
baseURL: 'https://cdn.scaleflex.it/demo/',
apiVersion: 'v7' // optional
};
```
- disable API version
```javascript
const cloudimageConfig = {
token: 'demo',
baseURL: 'https://cdn.scaleflex.it/demo/',
apiVersion: null // optional
};
```
###### Type: **bool** | Default: **false**
If set to **true** the plugin will only add query params to the given source of image.
###### Type: **Bool** | Default: **true** | _optional_
Only images close to the client's viewport will be loaded, hence accelerating the page loading time. The plugin uses
###### Type: **String** | Default: **'org_if_sml=1'** | _optional_
Applies default Cloudimage operations/ filters to your image, e.g. brightness, contrast, rotation...
Multiple params can be applied, separated by "```&```" e.g. func=fit&w=400&h=400&bg_colour=f2f7fa
```javascript
params: 'org_if_sml=1&func=fit&w=400&h=400&bg_colour=f2f7fa'
```
#### alternative syntax: type: **Object**
```javascript
params: {
org_if_sml: 1,
grey: 1,
...
}
```

## server-side rendering (SSR) vs client-side rendering (CSR)
Despite the plugin **by default** rendering the low-preview image on the server and on the client it renders the optimized image relative to the container size. you can render both low-preview and optimized images on the server-side.
by using srr config.
### limitFactor
###### Type: **Number** | Default: **100** | _optional_
Rounds up the size of an image to the nearest limitFactor value.
For example:
* for an image with width **358px** and limitFactor equal to **100**, the plugin will round up to 400px;
* for an image with width **358px** and limitFactor equal to **5**, the plugin will round up to 360px.
### devicePixelRatioList
###### Type: **[Number,...]** | Default: **[1, 1.5, 2]** | _optional_
List of supported device pixel ratios. If there is no need to support retina devices, you should set an empty array `devicePixelRatioList: []`.
###### Type: **Boolean** | Default: **false**
Render both low-quality preview and the optimized image on the server.
if **ssr** set to true we can't detect the image container width or the device pixel ratio. so the plugin will generate a srcset relative to device sizes in next.config.js
###### Type: **Number** | Default: **50**
The quality of the low-preview image relative to the optimized image.
An integer between `1` and `100`, where `100` is best quality.
### quality
###### Type: **Number** | Default: **75**
The quality of the optimized image.
An integer between `1` and `100`, where `100` is best quality.
###### Type: **String** | Default: **responsive**
The layout behavior of the image as the viewport changes size.
see layout.
###### Type: **String** | Default: **cover**
Defines how the image will fit into its parent container.
see objectFit.
###### Type: **String** | Default: **center**
Defines how the image is positioned within its parent element.
see objectPosition.
###### Type: **String** | Default: **800ms**
Defines the transition duration of animation while switching between low-preview image and the optimized image.
**NOTE:**
Set it to `0ms` to disable animation.
## Image properties
The following config can be used per-image basis.
- lazyLoading
- doNotReplaceURL
- params
- lowPreviewQuality
- quality
- layout
- objectFit
- objectPosition
- transitionDuration
### src
###### Type: **String** | Default: **undefined** | _required_
Original image hosted on your web server. You can use absolute path or
relative to the baseUrl in your config.
**NOTES:**
The plugin uses a special algorithm to detect the width of image container and set the image size accordingly.
This is the recommended way of using the Cloudimage Responsive plugin.
### onImgLoad
###### Type: **function** | Default: **undefined**
A function to be executed after the image is loaded
```jsx
{ console.log(event); }}/>
```
### width
###### Type: **String** (e.g. 300px, 20vw) | Default: **undefined**
If set, the plugin will use the width as a fixed value and change only according to the device pixel ratio.
**NOTE: while using ssr consider to set a suitable layout to the image.**
### height
###### Type: **String** (e.g. 300px, 20vh) | Default: **undefined**
If set, the plugin will use the width as a fixed value and change only according to the device pixel ratio.
**NOTE: while using ssr consider to set a suitable layout to the image.**
Tested in all modern browsers and IE 11.
