Package Exports

cloudinary

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (cloudinary) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Try it right away

Note: Replace demo in all the following examples with your Cloudinary's cloud name.

Accessing an uploaded image with the sample public ID through a CDN:

http://res.cloudinary.com/demo/image/upload/sample.jpg

Sample

Generating a 150x100 version of the sample image and downloading it through a CDN:

http://res.cloudinary.com/demo/image/upload/w_150,h_100,c_fill/sample.jpg

Sample 150x100

Converting to a 150x100 PNG with rounded corners of 20 pixels:

http://res.cloudinary.com/demo/image/upload/w_150,h_100,c_fill,r_20/sample.png

Sample 150x150 Rounded PNG

For plenty more transformation options, see our image transformations documentation.

Generating a 120x90 thumbnail based on automatic face detection of the Facebook profile picture of Bill Clinton:

For more details, see our documentation for embedding Facebook and Twitter profile pictures.

Usage

Configuration

Each request for building a URL of a remote cloud resource must have the cloud_name parameter set. Each request to our secure APIs (e.g., image uploads, eager sprite generation) must have the api_key and api_secret parameters set. See API, URLs and access identifiers for more details.

Setting the cloud_name, api_key and api_secret parameters can be done either directly in each call to a Cloudinary method, by calling the cloudinary.config(), or by using the CLOUDINARY_URL environment variable.

Embedding and transforming images

Any image uploaded to Cloudinary can be transformed and embedded using powerful view helper methods:

The following example generates the url for accessing an uploaded sample image while transforming it to fill a 100x150 rectangle:

cloudinary.url("sample.jpg", {width: 100, height: 150, crop: "fill"})

Another example, emedding a smaller version of an uploaded image while generating a 90x90 face detection based thumbnail:

cloudinary.url("woman.jpg", {width: 90, height: 90, crop: "thumb", gravity: "face"})

You can provide either a Facebook name or a numeric ID of a Facebook profile or a fan page.

Embedding a Facebook profile to match your graphic design is very simple:

cloudinary.url("billclinton.jpg", {width: 90, height: 130, type: "facebook", crop: "fill", gravity: "north_west"})

Same goes for Twitter:

cloudinary.url("billclinton.jpg", {type: "twitter_name"})

Upload

Assuming you have your Cloudinary configuration parameters defined (cloud_name, api_key, api_secret), uploading to Cloudinary is very simple.

The following example uploads a local JPG to the cloud:

 var cloudinary = require('cloudinary')
    
cloudinary.uploader.upload("my_picture.jpg", function(result) { console.log(result) })

Below is an example of an upload's result:

 { public_id: '4srvcynxrf5j87niqcx6w',
   version: 1340625837,
   signature: '01234567890abcdef01234567890abcdef012345',
   width: 200,
   height: 200,
   format: 'jpg',
   resource_type: 'image',
   url: 'http://res.cloudinary.com/demo/image/upload/v1340625837/4srvcynxrf5j87niqcx6w.jpg',
   secure_url: 'https://d3jpl91pxevbkh.cloudfront.net/demo/image/upload/v1340625837/4srvcynxrf5j87niqcx6w.jpg' }

The uploaded image is assigned a randomly generated public ID. The image is immediately available for download through a CDN:

cloudinary.url("abcfrmo8zul1mafopawefg.jpg")
    
http://res.cloudinary.com/demo/image/upload/abcfrmo8zul1mafopawefg.jpg

You can also specify your own public ID:

cloudinary.uploader.upload("http://www.example.com/image.jpg", function(result) { console.log(result) }, {public_id: 'sample_remote'})

cloudinary.url("sample_remote.jpg")

http://res.cloudinary.com/demo/image/upload/sample_remote.jpg

cloudinary.image

Returns an html image tag pointing to Cloudinary.

Usage:

cloudinary.image("sample", {format: "png", width: 100, height: 100, crop: "fill"})

// <img src='http://res.cloudinary.com/demo/image/upload/c_fill,h_100,w_100/sample.png' height='100' width='100'/>
