Package Exports

imager

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 (imager) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

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')
