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

Flexible way to resize and upload images to Rackspace cloudfiles for Node.js. 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

Upload example:

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

app.post('/upload',  function(req, res) {
  //With Scope `projects` (look at example of configuration file)
  imager.upload(req, res, function(err, file, cdnUri, res){
    console.log("FILE UPLOADED: " + cdnUri+'/'+file);
    // THIS YOU CAN SAVE FILE TO DATABASE FOR EXAMPLE
    res.end();
  }, '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
