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

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

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

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

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

2. Upload files from disk

You can upload a single file or multiple files by providing the paths to all the files in an array

Upload Single file from disk:

imager.upload('path/to/file.jpg', function(err, files, cdnUri){
    // do your stuff
}, 'projects')

Upload multiple files from disk:

var files = ['file1.jpg', 'file2.jpg']
imager.upload(files, function(err, files, cdnUri){
    // do your stuff
}, 'projects')

3. Upload files from remote url

imager.uploadRemoteImage('https://www.google.co.in/images/srpr/logo3w.png', function(err, files, cdnUri){
    // do your stuff
}, 'projects')

Removing file(s)

1. Remove a single file

imager.remove('1330838831049.png', function (err) {
    // do your stuff
}, 'projects')

2. Remove multiple files

var files = ['1330838831049.png', '1330838831049.png']
imager.remove(files, function (err) {
    // do your stuff
}, 'projects')
