Usage

Setup

There are several ways to configure cloudinary-core:

Explicitly
var cl = cloudinary.Cloudinary.new( { cloud_name: "demo"});
Using the config function
// Using the config function
var cl = cloudinary.Cloudinary.new();
cl.config( "cloud_name", "demo");
From meta tags in the current HTML document

When using the library in a browser environment, you can use meta tags to define the configuration options.

The init() function is a convenience function that invokes both fromDocument() and fromEnvironment().

For example, add the following to the header tag:

<meta name="cloudinary_cloud_name" content="demo">

In your JavaScript source, invoke fromDocument():

var cl = cloudinary.Cloudinary.new();
cl.fromDocument();
// or
cl.init();
From environment variables

When using the library in a backend environment such as NodeJS, you can use an environment variable to define the configuration options.

Set the environment variable, for example:

export CLOUDINARY_URL=cloudinary://demo

In your JavaScript source, invoke fromEnvironment():

var cl = cloudinary.Cloudinary.new();
cl.fromEnvironment();
// or
cl.init();

Transform and Optimize Assets

// Apply a single transformation
cl.url( "sample", { crop: "scale", width: "200", angle: "10" })

// Chain (compose) multiple transformations
cl.url( "sample", {
  transformation: [
    { angle: -45 },
    { effect: "trim", angle: "45", crop: "scale", width: "600" },
    { overlay: "text:Arial_100:Hello" }
  ]
});
