Cloudinary React Components

Ringo

I’ve been experimenting a lot with both React and Cloudinary over the past six months and it’s been a blast — I’m learning a ton while also recovering the ambition and thirst I had as a young developer.  React has been a revelation:  an advanced JavaScript framework that doesn’t overcomplicate things and has encouraged me to learn more ESNext and Babel.  Cloudinary lets me do amazing stuff with images and media, like creating Instagram-Like Filters, transform images, and more, all by modifying the image URL.  Cloudinary provides APIs for a number of different languages (Node.js, Python, PHP, etc.) but they’ve gone a step further and now offer a set of React components to use in your React app!

Installing cloudinary-react

Cloudinary’s React component set is available via the cloudinary-react name:

yarn add cloudinary-react
# or `npm install cloudinary-react`

Use npm install or yarn add to get these components.

Cloudinary Components

Cloudinary provides CloudinaryContext, Image, Video, and Transformation components.  They are available within your app using require or import:

import { Image, Video, Transformation, CloudinaryContext } from 'cloudinary-react';

Let’s have a look at each component type!

Image

The Image component is the simplest of components, allowing all types of transformations:

The code above transpiles to:

Ringo

Note that you can add all of the usual attributes for each image, like alt, title, and so on.

Video

The Video component is also very simple, working as you think it would:

All transformations can also be applied to videos as well!

Transformation

Image components can contain any number of Transformation components to modify the outgoing image:


Cloudinary’s Transformation documentation is an excellent reference for the amazing breadth of transformations.  If you have any question about how the transformation should be added as an attribute, click the Node.js tab in the Cloudinary documentation examples to see what your keys and values should be.

Cloudinary Context

The CloudinaryContext component allows for intelligent grouping of media and effects to be applied to its child content, be it Image, Video, Transformation components:

With the example above, all Image components have the effect designated by its parent CloudinaryContext, an awesome way to cut down on repeated code and keep your JSX tight and organized! You can even stack CloudinaryContext components:

Creating a Quick Instagram-style Experiment

One of the reasons I love React (and more specifically create-react-app) is that it lets me put together a dynamic app really quickly.  Since Cloudinary provides a few dozen artistic filters, I thought it would be fun to create a very simple Instagram-like app using the Cloudinary’s React library.  Then minutes later I had something:

class App extends Component { state = { width: 600, filter: null }; filters = [ 'al_dente', 'audrey', 'aurora', 'daguerre', 'eucalyptus', 'fes', 'frost', 'hairspray', 'hokusai', 'incognito', 'linen', 'peacock', 'primavera', 'quartz', 'red_rock', 'refresh', 'sizzle', 'sonnet', 'ukulele', 'zorro' ]; onPreviewClick(event) { this.setState({ filter: event.target.src }); } render() { return ( 
{ this.state.filter && () }
{this.filters.map(filter => (
{filter}
))}
); } }

The result looks like:

Cloudinary React

Cloudinary provides APIs and helpers for every major programming language and now provides jQuery and React library resources to make coding your media-rich applications with ease.  Especially useful are the Transformation and CloudinaryContext components which allow your code to stay clean and brief.  cloudinary-react is just another awesome reason to look to Cloudinary for all of your media needs!
