The new component is backwards compatible, but deprecates some props and benefits from some breaking changes. + +### Migrating to the new `Image` + +The new `Image` component is responsive by default, and requires less configuration to ensure the right image size is being rendered on all screen sizes. + +**Before** + +```jsx + +``` + +**After** + +```jsx + +``` + +Note that `widths` and `loaderOptions` have now been deprecated, declaring `width` is no longer necessary, and we’ve added an `aspectRatio` prop: + +- `widths` is now calculated automatically based on a new `srcSetOptions` prop (see below for details). +- `loaderOptions` has been removed in favour of declaring `crop` and `src` as props. `width` and `height` should only be set as props if rendered a fixed image size, and otherwise default to `100%` and `auto` respectively, with the loader calculating each dynamically. +- `aspectRatio` is calculated automatically using `data.width` and `data.height` (if available) — but if you want to present an image with an aspect ratio other than what was uploaded, you can set using the format `Int/Int` (e.g. `3/2`, [see MDN docs for more info](https://developer.mozilla.org/en-US/docs/Web/CSS/aspect-ratio)); if you've set an `aspectRatio`, we will default the crop to be `crop: center` (in the example above we've specified this to use `left` instead). + +### Examples + + + +#### Basic Usage + +```jsx + +``` + +This would use all default props, which if exhaustively declared would be the same as typing: + +```jsx + +``` + +An alternative way to write this without using `data` would be to use the `src`, `alt`, and `aspectRatio` props. For example: + +```jsx +{data.altText} +``` + +Assuming `data` had the following shape: + +```json +{ + url: "https://cdn.shopify.com/s/files/1/0551/4566/0472/products/Main.jpg", + altText: "alt text", + width: "4000" + height: "4000" +} +``` + +All three above examples would result in the following HTML: + +```html +alt text +``` + +#### Fixed-size Images + +When using images that are meant to be a fixed size, like showing a preview image of a product in the cart, instead of using `aspectRatio`, you'll instead declare `width` and `height` manually with fixed values. For example: + +```jsx + +``` + +Instead of generating 15 images for a broad range of screen sizes, `Image` will instead only generate 3, for various screen pixel densities. The above example would result in the following HTML: + +```html +alt text +``` + +If you don't want to have a fixed aspect ratio, and instead respect whatever is returned from your query, the following syntax can also be used: + +```jsx + +``` + +Which would result in the same HTML as above, however the generated URLs would not have `height` or `crop` parameters appended to them, and the generated `aspect-ratio` in `style` would be `4000 / 4000` (if using the same `data` values as our original example). + +#### Custom Loaders + +If your image isn't coming from the Storefront API, but you still want to take advantage of the `Image` component, you can pass a custom `loader` prop, provided the CDN you're working with supports URL-based transformations. + +The `loader` is a function which expects a `params` argument of the following type: + +```ts +type LoaderParams = { + /** The base URL of the image */ + src?: ImageType['url']; + /** The URL param that controls width */ + width?: number; + /** The URL param that controls height */ + height?: number; + /** The URL param that controls the cropping region */ + crop?: Crop; +}; +``` + +Here is an example of using `Image` with a custom loader function: + +```jsx +const customLoader = ({src, width, height, crop}) => { + return `${src}?w=${width}&h=${height}&gravity=${crop}`; +}; + +export default function CustomImage(props) { + ; +} + +// In Use: + +; +``` + +If your CDN happens to support the same semantics as Shopify (URL params of `width`, `height`, and `crop`) — the default loader will work a non-Shopify `src` attribute. + +An example output might look like: `https://mycdn.com/image.jpeg?width=100&height=100&crop=center` + +### Additional changes + +- Added the `srcSetOptions` prop used to create the image URLs used in `srcset`. It’s an object with the following keys and defaults: + + ```js + srcSetOptions = { + intervals: 15, // The number of sizes to generate + startingWidth: 200, // The smalles image size + incrementSize: 200, // The increment by to increase for each size, in pixesl + placeholderWidth: 100, // The size used for placeholder fallback images + }; + ``` + +- Added an export for `IMAGE_FRAGMENT`, which can be imported from Hydrogen and used in any Storefront API query, which will fetch the required fields needed by the component. + +- Added an export for `shopifyLoader` for using Storefront API responses in conjunction with alternative frameworks that already have their own `Image` component, like Next.js diff --git a/package-lock.json b/package-lock.json index b01e13be9d..2e7d9219f7 100644 --- a/package-lock.json +++ b/package-lock.json @@ -5066,37 +5066,78 @@ } }, "node_modules/@miniflare/cache": { -
