# msgpack for node
|

|
A handwritten msgpack encoder and decoder for Node.JS.
|
||
|
|
|
||
|
|
The original format can be found at <http://wiki.msgpack.org/display/MSGPACK/Format+specification>
|
||
|
|
|
||
|
|
|
||
|
|
## Extension
|
||
|
|
|
||
|
|
I've extended the format a little to allow for encoding and decoding of `undefined` and `Buffer` instances.
|
||
|
|
|
||
|
|
This required three new type codes that were previously marked as "reserved".
|
||
|
|
This change means that using these new types will render your serialized data
|
||
|
|
incompatible with other messagepack implementations that don't have the same
|
||
|
|
extension.
|
||
|
|
|
||
|
|
There are two new types for storing node `Buffer` instances. These work just
|
||
|
|
like "raw 16" and "raw 32" except they are node buffers instead of strings.
|
||
|
|
|
||
|
|
buffer 16 11011000 0xd8
|
||
|
|
buffer 32 11011001 0xd9
|
||
|
|
|
||
|
|
Also I've added a type for `undefined` that works just like the `null` type.
|
||
|
|
|
||
|
|
undefined 11000100 0xc4
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
``` javascript
|
||
|
|
var msgpack = require('msgpack');
|
||
|
|
var assert = require('assert');
|
||
|
|
|
||
|
|
var initial = {Hello: "World"};
|
||
|
|
var encoded = msgpack.encode(initial);
|
||
|
|
var decoded = msgpack.decode(encoded);
|
||
|
|
|
||
|
|
assert.deepEqual(initial, decoded);
|
||
|
|
```
