Cloudinary Frontend Frameworks

About this project

This project contains SDKs designed to work with Cloudinary url-gen.
These SDKs render CloudinaryImage or CloudinaryVideo objects into the DOM.

Packages contained within this project:


  • The React SDK used to render an image & video component. NPM | Reference
  • The Angular SDK used to render an image & video component. NPM | Reference

Each SDK also contains advanced features in the form of plugins, which extend the native HTMLImage and HTMLVideo elements.

  • accessibility - Used to make your images more accessible to your users with visual disabilities.
  • lazyload - Used to delay loading images if they are not yet visible on the screen.
  • placeholder - Used to display a lightweight version of an image while the target image is downloading.
  • responsive - Used to resize your images automatically based on the viewport size.

Development setup

To build and link project:

  • clone project
  • npm run quickstart

Installation

To get started, install the npm client package of your choice along with our base package. For example, to use Cloudinary in a React environment, the following packages should be installed:

npm i @cloudinary/react @cloudinary/url-gen

Note: To use Angular install @cloudinary/ng.

Simple usage

The following is a simple example using React. For more information on React and other frameworks, navigate to the specific reference using the Packages menu.

// Import the Cloudinary class, and the plugins you want to use.
// In this case, we import a Cloudinary image type, accessibility and responsive.

import React, { Component } from 'react'
import {Cloudinary} from "@cloudinary/url-gen";
import { AdvancedImage, accessibility, responsive } from '@cloudinary/react';

// Once per project/app - configure your instance.
// See the documentation in @cloudinary/url-gen for more information. 
const myCld = new Cloudinary({ cloudName: 'demo'});

// Render your component.
 const App = () => {
    // Create your image.
    // This creates a new image object:
    let img = myCld().image('sample');
    return (
        <div>
            <AdvancedImage cldImg={img} plugins={[responsive(), accessibility()]}/>
        </div>
    )
  };

Plugin Order

We recommend the following order when using our plugins to achieve the best results:

<AdvancedImage plugins={[lazyload(),responsive(), accessibility(), placeholder()]}/>

You can omit any plugin, but the order from above should remain.
