Simple object with functions encode/decode, serialization/deserialization.


Via npm on Node:

npm install simplefunc


Sometimes, you need to define an object with attributes and functions, and send it to other machine or process. Functions are not serialized, so, an special processing is needed. SimpleFunc is a helper to encode objects with instance funcions so they can be serialized/deserializas from/to JSON. You can encode, decode without using JSON, too.

Reference in your program:

var simplefunc = require('simplefunc');

Encoding a value

var encoded = simplefunc.encode(value);

Most value are encoded as themselves. The current implementation returns an encoded result if the original value is an object and it has functions. If value is an object with functions, an object is returned, with two properties:

  • _obj: with the properties of the original value, that are NOT functions.
  • _fns: with the properties of the original value that ARE functions, encoding in an array with its parameters and code

Only the first level of properties is encoded: no attempt to make a deep encode (maybe in next versions).

If the value to encode is a function, an object is returned with an attribute _fn with an array containing the original function arguments and code serialized to string.

Encoding and decoding a value

var encoded = simplefunc.encode(value);
var newvalue = simplefunc.decode(encoded);

You can convert a value to/from a JSON string:

var json = simplefunc.toJson(value);
var newvalue = simplefunc.fromJson(encoded);


git clone git://
cd SimpleFunc
npm install
npm test



To do
