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