imager

Imager

A Node.js module to easily resize, crop and upload images to Rackspace cloudfiles. Possible to add different versions of the same file in cropped or resized variant.

Installation

$ npm install imager

Usage

You need to create imager configuration file with image variants and your storages

Example config with scopes:

{
  "variants": {
    "projects": {
      "resize": {
        "mini" : "300x200",
        "preview": "800x600"
      },
      "crop": {
        "thumb": "200x200"
      }
    },

    "gallery": {
      "crop": {
        "thumb": "100x100"
      }
    }
  },

  "storage": {
    "rs": {
      "auth": {
        "username": "USERNAME",
        "apiKey": "API_KEY",
        "host": "lon.auth.api.rackspacecloud.com"
      },
      "container": "CONTAINER_NAME"
    }
  }
}

Now you can use Imager

var  Imager = require('imager');
var imager = new Imager({storage : "rs", config_file: "path_to_imager_config.json"})

Note: More storage systems yet to come

UPLOAD FILE

Upload example:

app.get('/upload_form', function(req, res) {
  res.writeHead(200, {'content-type': 'text/html'});
  res.end(
    '<form action="/upload_form" enctype="multipart/form-data" method="post">'+
    '<input type="text" name="title"><br>'+
    '<input type="file" name="image"><br>'+
    '<input type="submit" value="Upload">'+
    '</form>'
  );
});

app.post('/upload',  function(req, res) {
  //With Scope `items` (look at example of configuration file)
  imager.upload(req, res, function(err, files, cdnUri, res){
    console.log({ uri : cdnUri, files : files });
    res.end()
  }, 'items')
});

REMOVE FILE

imager.remove('1330838831049.png', function (err) {
  if (err) throw err
  console.log('removed')
}, 'projects')

To-do's

• Support amazon storage
• Support filesystem storage
• Remove using of eval
• Add functionality to remove files
• Add functionality to get the image url
• Add functionality to get remote images, process the image and then upload to various storage systems
• Write tests
