AMF.js

As a simple AMF (Action Message Format) library for Node.js, AMF.js is capable of encoding and decoding most AMF0 and AMF3 types. Simply hook the AMFEncoder or AMFDecoder up to a stream and it will be able to read or write to/from the stream.

Installation

npm install [--save-dev] amfjs

Usage

- __Encoding__
``
var amfjs = require("amfjs")
var encoder = new amfjs.AMFEncoder(someKindOfWritableStream)
encoder.writeObject(10, amfjs.AMF0) //Write as AMF0
encoder.writeObject(10, amfjs.AMF3) //Write as AMF3
`
- __Decoding__

`
var amfjs = require("amfjs")
var decoder = new amfjs.AMFDecoder(someKindOfReadableStream)
var value = decoder.decode(amfjs.AMF0) //Decode an AMF0 object
var value = decoder.decode(amfjs.AMF3) //Decode an AMF3 object
`
- __Encoding custom objects__
Simply extend the Serializable class and call writeObject with an instance of your class. Any fields in the serializable not starting with __ will automatically be encoded:
`
class MySerializable extends Serializable
constructor: ->
super "name.of.the.serializable"
`

- __Custom Externalizables__
Simply extend the Externalizable class and register it in the decoder to allow for the custom encoding of objects. The write method will be called whenever an Externalizable needs to be encoded and the this value will be set to the encoder. The static read method will be called whenever an object with the Externizable's class is found. As with write, while invoking read the this value is set to the decoder.
`
class MyExternalizable extends Externalizable
constructor: ->
super "name.of.the.externalizable"
write: ->
//Do some writing stuff
@write 0x10
@read: ->
//Do some reading stuff and return the read object
@readByte()
return new MyExternalizable()

//Register the externalizable
var amfjs = require("amfjs")
amfjs.AMFDecoder.register("name.of.the.externalizable", MyExternalizable, amfjs.AMF0) //Or AMF3
