React Imgix

A React component that renders images using the Imgix API. It uses the smallest images possible, and does cool stuff, like cropping to faces by default.

Usage

import Imgix from 'react-imgix'

<Imgix src={string} />

Props

src={string}

required, usually in the form: https://[your_domain].imgix.net/[image]. Don't include any parameters.

aggressiveLoad={bool}

whether to wait until the component has mounted to render the image, useful for auto-sizing and server-side rendering, defaults to false

auto={array}

array of values to pass to Imgix's auto param, defaults to ['format']

type={string}

what kind of component to render, one of img, bg, picture, source. Defaults to img

component={string}

wrapper component to use when rendering a bg, defaults to div

className={string}

className applied to top level component. To set className on the image itself see imgProps.

entropy={bool}

whether or not to crop using points of interest. See Imgix API for more details. Defaults to false

faces={bool}

whether to crop to faces, defaults to true

crop={string}

sets specific crop, overriding faces and entropy flags. Useful for specifying fallbacks for faces like faces,top,right

fit={string}

see Imgix's API, defaults to crop

fluid={bool}

whether to fit the image requested to the size of the component rendered, defaults to true

onMounted={func}

called on componentDidMount with the mounted DOM node as an argument

precision={number}

round to nearest x for image width and height, useful for caching, defaults to 100

height={number}

force images to be a certain height, overrides precision

width={number}

force images to be a certain width, overrides precision

generateSrcSet={bool}

generate 2x and 3x src sets when using an <img> tag. Defaults to true

customParams={object}

any other Imgix params to add to the image src

For example:

<Imgix
    customParams={{mask: 'ellipse'}}
/>

imgProps={object}

any other attributes to add to the html node (example: alt, data-*, className)

Note: if you use type='bg' the css property background-size is set to 'cover' by default. To override this behaviour you can change the background size by overriding it with a string such as 'contain', or to null for controlling the style with CSS.

<Imgix
    src={src}
    type='bg'
    imgProps={{style: {backgroundSize: 'contain'}}}
/>

Picture Support

Using the element you can create responsive images:

<Imgix src={src} type='picture'>
  <Imgix src={src} width={400} type='source' imgProps={{media: '(min-width: 768px)'}}/>
  <Imgix src={src} width={200} type='source' imgProps={{media: '(min-width: 320px)'}}/>
  <Imgix src={src} width={100} type='img' />
</Imgix>

The final type='img' component will be created with the options passed into the parent <picture> container if it's not provided so the above is equivalent to:

<Imgix src={src} width={100} type='picture'>
  <Imgix src={src} width={400} type='source' imgProps={{media: '(min-width: 768px)'}}/>
  <Imgix src={src} width={200} type='source' imgProps={{media: '(min-width: 320px)'}}/>
</Imgix>

Installation

With npm:

npm install --save react-imgix

With yarn:

yarn add react-imgix
