# svelte-cloudinary
This is a little library that aims at integrating and making it easier to use the svelte with [Cloudinary](https://cloudinary.com/).
There is an official integration comming, but it's not ready and for not does not work great.
## 🚀 Quickstart
```bash
yarn add svelte-cloudinary
```
```svelte
<script>
import { image, initialize } from 'svelte-cloudinary'
initialize({ cloud_name: 'myCloudinaryCloud' })
const src = 'my/cloudinary/asset'
</script>
<style>
img {
width: 50vw;
height: 50vh;
object-fit: cover;
}
</style>
<img
use:image={{ src, bind: true, options: { crop: 'fill' } }}
class="home-img"
alt="background" />
```
This will formulate the Cloudinary url and insert it into the `img.src` property.
Also it will resize to the `img` object itself because we set `bind: true`.
## 🗂 Docs
The `image` action takes 3 parameters.
### `src`
The `publicId` of your asset.
### `bind`
This is a utility for setting width and/or height automatically based on the size of a rendered element in the DOM.
- `true`: Uses the size of the img node itself
- `'.someClass'`: Searches for the element closest to the image that matches the css query and takes that as size
- `{ height: document.querySelector('#some'), height: '#some' }`: Set height and/or width independently from another. Can be an element or css selector.
###### Examples
```svelte
<!-- Simple -->
<img
use:image={{ src, bind: true, }}
/>
```
```svelte
<!-- Bind size to parent with selectors -->
<div class="wrapper"
<img
use:image={{ src, bind: '.wrapper', }}
/>
</div>
```
```svelte
<!-- Bind width to parent with element -->
<div class="wrapper"
<img
use:image={{ src, bind: { width: '.wrapper' }, }}
/>
</div>
```
### `options`
Native cloudinary options. See [here for official docs](https://cloudinary.com/documentation/image_transformations)
