A JavaScript library which extends Flow.js and allows to use not resumable uploads for older browsers, such as IE7, IE8 and IE9.

This library is written in the same style as Flow.js and follows same api. This means that with minimal effort we can have both: awesome Flow.js features and support for older browsers.

use bower:

    bower install fusty-flow.js#~1

use cdn, look for available packages at https://www.jsdelivr.com/?query=flow.js

or use git clone

    git clone https://github.com/flowjs/fusty-flow.js

Same as Flow.js, except of calling Flow constructor we call fustyFlowFactory function. This function automatically checks if Flow.js is supported.

var uploader = fustyFlowFactory({
  target:'/api/photo/redeem-upload-token', 
  query:{upload_token:'my_token'}
});

uploader is going to be instance of Flow if it is supported, otherwise instance of FustyFlow will be returned.

This library has same methods and properties as Flow except it handles not resumable uploads. Additional options:

• matchJSON - removes html from returned response on fileSuccess event. Default false.

File is instance of FustyFlowFile. It has same methods and properties as FlowFile.

Differences in properties:

• size - undefined
• uniqueIdentifier - is generated in uuid format
• progress - equals to 0 or 1
• chunks - undefined
• file - undefined

Differences in methods:

• getType - returns undefined
• timeRemaining - returns undefined
• sizeUploaded - returns undefined

To create your own build, clone this repository and run grunt build.

Command will concat and minify flow.js, fusty-flow.js and fusty-flow-factory.js files. Look for fusty-flow.js and fusty-flow.min.js in build directory.

Minified library size is about 18kb, which is much less then other alternative libraries with IE7+ support.
