simple-vcdiff

node-simple-vcdiff

A really simple wrapper around open-vcdiff

Description

This wraps the simplest API of Open-VCDiff for node v0.12

API

Require

var vcdiff = require('simple-vcdiff');

Encode

Compute the difference between the dictionnary and the target, sending the result buffer to the callback:

vcdiff.Encode(dictionary, target, callback);

Decode

Apply a previously computed delta to the dictionnary, sending the result buffer to the callback:

vcdiff.Decode(dictionary, delta, callback);

Callback

function (bufferOut) {}

Sample

var vcdiff = require('simple-vcdiff');
 
var dictionary = new Buffer('testing data.');
var target = new Buffer('testing dota is not the same.');
 
vcdiff.Encode(dictionary, target, function(bufferDelta) {
    vcdiff.Decode(dictionary, bufferDelta, function(bufferOut) {
        // bufferOut should be identical to target.
    });
});

Install

npm install simple-vcdiff
