A metalsmith plugin for retrieving data from the Cloudinary api

stack overflow slack chat

Cloudinary is a CDN that allows you to upload images and apply transformations when retrieving them. This is immensely useful when working with responsive images, because now you no longer have to process images during your build process.

Just add parameters to your images' url, and Cloudinary will supply the image at the correct dimensions via their CDN. I recommend cloudinate to automate the uploading of your images to Cloudinary. That being said, Cloudinary accepts all kinds of files, so this plugin and cloudinate can of course be used for all kinds of other purposes as well.

For support questions please use stack overflow or our slack channel. For questions about Cloudinary try the aforementioned channels, as well as their documentation. Specifically the list resources part of the admin api, which is what this plugin provides access to.

Installation

$ npm install metalsmith-cloudinary

Example

Configuration in metalsmith.json:

{
  "plugins": {
    "metalsmith-cloudinary": {
      "cloud_name": "your_cloud_name_here",
      "api_key": "your_api_key_here",
      "api_secret": "your_api_secret_here",
    }
  }
}

metalsmith-cloudinary will query the Cloudinary api and store the results in the global metadata under cloudinary, indexed by your assets' public_id. The contents will of course differ depending on what you've uploaded, but will resemble:

// images/1 is the public_id
'images/1': {
  "format": "jpg",
  "version": 1333013579,
  "resource_type": "image",
  "type": "upload",
  "created_at": "2012-03-29T09:32:59Z",
  "bytes": 128891,
  "width": 283,
  "height": 424,
  "url": "http://res.cloudinary.com/demo/image/upload/v1333013579/1.jpg",
  "secure_url": "https://res.cloudinary.com/demo/image/upload/v1333013579/1.jpg"
},
// images/2 is the public_id
'images/2': {
  "format": "jpg",
  "version": 1333013579,
  "resource_type": "image",
  "type": "upload",
  "created_at": "2012-03-29T09:32:59Z",
  "bytes": 128891,
  "width": 283,
  "height": 424,
  "url": "http://res.cloudinary.com/demo/image/upload/v1333013579/2.jpg",
  "secure_url": "https://res.cloudinary.com/demo/image/upload/v1333013579/2.jpg"
},

Which means that in your templates you could use (with something like swig and metalsmith-in-place):

{{ cloudinary['images/1'].secure_url }}
{{! would be rendered to: https://res.cloudinary.com/demo/image/upload/v1333013579/1.jpg }}

Options

You can pass options to metalsmith-cloudinary with the Javascript API or CLI. The options are:

  • cloud_name: your cloud name (required)
  • api_key: your api key (required)
  • api_secret: your api secret (required)
  • params: an optional object of parameters to pass to the cloudinary api (optional)

credentials

Your Cloudinary API credentials. So this metalsmith.json:

{
  "plugins": {
    "metalsmith-cloudinary": {
      "cloud_name": "your_cloud_name_here",
      "api_key": "your_api_key_here",
      "api_secret": "your_api_secret_here",
    }
  }
}

Would retrieve all files you've uploaded to Cloudinary and store them in your metadata.

params

An object of optional parameters to pass to the Cloudinary API. By default the max_results option is set to the maximum (500). So this metalsmith.json:

{
  "plugins": {
    "metalsmith-cloudinary": {
      "cloud_name": "your_cloud_name_here",
      "api_key": "your_api_key_here",
      "api_secret": "your_api_secret_here",
      "params": {
        "max_results": 10
      }
    }
  }
}

Would retrieve 10 results at maximum and store them in your metadata.
