Bencode-js

JavaScript solution for implmenting the encoding and decoding of the Bencode format.

• BitTorrent Specification
• Bencode

Currently only works in browser environments, but I intend to add support for CommonJS modules.

This solution uses classes and OOP.

This repo is implemented in a Ruby environment, for easy Jasmine testing integration.

Usage

Include the files in the webpage. Both the Encode and Decode classes use functions from the utilities module (aka utilities.js is a dependency and is required in order for Encode and Decode to work). I recommend combining all three files into one, no need for extra HTTP requests.

Encode

The encode() function is attached to Object, Array, String and Number's prototype, so you can just call it on an instance of those types like so:

"string".encode()              // => "6:string"
(123).encode()                 // => "i123e"
["str", 123].encode()          // => "l3:stri123ee"
({ key: "value" }).encode()    // => "d3:key5:valuee"

Decode

The decode() function is attached to String's prototype and is therefore available on an instance of a string like so:

"d3:key5:valuee".decode()      // => { key: "value" }

Classes

You shouldn't need to directly access the classes (you should just call encode() and decode() on instances of objects), but if you do, the classes are namespaced under Bencode and attached to window:

window.Bencode.Encode
window.Bencode.Decode

TODOS

Needs much more thorough testing.

Needs much better Error handling.

Decode class (especially the decode() method in the Decode class) needs refactoring.

Implement it so it can be used in both a Browser and CommonJS environment.
