Imager

A Node.js module to easily resize, crop and upload images (with different variants and presets) to Rackspace cloudfiles.

Installation

$ npm install imager

Usage

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

Checkout the example config file imager-example.js in the repo

var Imager = require('imager');
  , imagerConfig = require('path/to/imager-config.js')
  , imager = new Imager(imagerConfig, 'Rackspace')

Uploading file(s)

The callback recieves an err object, a files array (containing the names of the files which were uploaded) and the cdnUri.

So if you have a variant, say thumb, then you can access the image by cdnUri+'/'+'thumb_'+files[0]. This would be the complete url of the image

  1. Form upload (multiple images)

    If you are using express, you will recieve all the form files in req.files.

    imager.upload(req.files.image, function(err, cdnUri, files) {
        // do your stuff
    }, 'projects')

    Here, projects is your scope or variant. If you don't specify the scope or the variant, imager will try to look for a default variant named default. You must either specify a variant like above or provide a default variant.

  2. Upload local images

    imager.upload(['/path/to/file'], function (err, cdnUri, files) {
      // do your stuff
    }, 'projects')
    
    Here files can be an array or a string. Make sure the path is
    absolute.
    
    ### Removing file(s)
    
    1. **Remove from cloudfiles**
    
    ```js
    var files = ['1330838831049.png', '1330838831049.png']
    imager.remove(files, function (err) {
        // do your stuff
    }, 'projects')

    Even here, if the variant is not specified, imager will try to look for the default variant. If neither of them are provided, you will get an error.

    Debugging

    If you specify debug: true in the imager config, you can see the logs of uploaded / removed files.

    To-do's

    • Support amazon storage
