Installation

via npm:

$ npm install diff-parser # use -g if you want to use diff2html

Usage

$ git diff [file|dir] > filename.diff
$ diff2html path/to/filename.diff > filename.html

var diffParser = require("diff-parser");
var diffFiles = diffParser.parse(diffString);
console.log(diffFiles); // here have all info you need.

Right now it only support git diff. So the next improvement should be support more type of diffs.
Let user customize their styles for the diff html page.
