Cloudinary URL-Gen SDK

Build Status

About

The Cloudinary URL-Gen SDK allows you to quickly and easily integrate your application with Cloudinary. Effortlessly optimize and transform your cloud's assets.

This SDK can also be used with popular frontend frameworks.

Additional documentation

This Readme provides basic installation and usage information. For the complete documentation, see the URL-Gen SDK Guide and the URL-Gen Reference.

NOTE: When using the url-gen library, an additional transformation-builder-sdk library is installed as a dependency. This library handles the transformation generation part of the URL and as such, all transformation actions are imported from this library. Therefore, you can import all transformations either from @cloudinary/url-gen (as demonstrated in the documentation), or directly from the transformation-builder-sdk library, for example:

import {scale} from '@cloudinary/transformation-builder-sdk/actions/resize';

You can find all available transformations in the Transformation Builder reference.

Installation

Install using your favorite package manager (yarn, npm)

npm install @cloudinary/url-gen
yarn add @cloudinary/url-gen

Usage

Setup

// Import the Cloudinary class
import {Cloudinary} from '@cloudinary/url-gen';

// Create your instance
const cld = new Cloudinary({
  cloud: {
    cloudName: 'demo'
  },
  url: {
    secure: true // force https, set to false to force http
  }
});

Transform and Optimize Assets

// Create a new instance if you haven't (see above for the details)
const cld = new Cloudinary({/*...*/})

// Let's create a new image
const myImage = cld.image('sample');

// Import the resize transformation and apply it to myImage
import {Resize} from '@cloudinary/url-gen/actions/resize';

// Resize the image to 100x100
myImage.resize(Resize.scale().width(100).height(100));

// When we're done, we can apply all our changes and create a URL.
const myURL = myImage.toURL();

// https://res.cloudinary.com/demo/image/upload/c_scale,w_100,h_100/sample
console.log(myURL);

Generate Image and Video URLs

The library supports transformations on both images and videos. Please use the appropriate method, as per below:

- Use `cld.image()` to generate image URLs and transformations
- Use `cld.video()` to generate video URLs and transformations

Both the image() and video() methods allow you to use toURL() to generate the final, transformed asset URL.

File upload

This SDK does not provide file upload functionality, however there are several methods of uploading from the client side.

Transpilation

@cloudinary/url-gen is shipped as untranspiled ES6 code. @cloudinary/url-gen is optimized around bundle size, as such we do not transpile our distributed modules, we leave the decision of what browsers to support, and what transpilations to apply, to you, the user.

Testing with Jest

As mentioned above, we're shipping @cloudinary/url-gen with ES6 code, as this provides great tree-shaking potential. it also requires a few adjustments when testing.

In jest.config, you'll need to add these lines to allow babel to transpile our code.

{
  "transform": {
    "node_modules/@cloudinary/url-gen": "babel-jest",
    "node_modules/@cloudinary/transformation-builder-sdk": "babel-jest"
  },
  "transformIgnorePatterns": ["/node_modules/(?!(@cloudinary/url-gen|@cloudinary/transformation-builder-sdk))"]
}

Make sure to install babel-jest: npm install babel-jest

You'll also need to ensure you have a babel.config.js file (and not a .babelrc), and that it's configured properly to transpile code,

As an example:

module.exports = {
  "presets": [
    "@babel/preset-env"
  ]
};
