Installation

Install as a dependency for your project (need python 2.x):

``bash
npm install --save bsdiff-nodejs
`

Usage

`javascript
const bsdiff = require('bsdiff-nodejs');
bsdiff.diff(oldFile, newFile, patchFile, function(result, err) {}); // Async
bsdiff.patch(oldfile, newfile, patchfile, function(result, err) {}); // Async

bsdiff.diffSync(oldFile, newFile, patchFile); // Sync
bsdiff.patchSync(oldfile, newfile, patchfile); // Sync
`

For example:

`javascript
const fs = require('fs');
const path = require('path');

const oldFile = path.join(__dirname, 'resources/react-0.3-stable.zip');
const newFile = path.join(__dirname, 'resources/react-0.4-stable.zip');
const patchFile = path.join(__dirname, 'resources/react.patch');
const generatedFile = path.join(__dirname, 'resources/react-generated.zip');

async function asyncCall() {
await bsdiff.diff(oldFile, newFile, patchFile, function (result) {
console.log('diff:' + String(result).padStart(4) + '%');
});

await bsdiff.patch(oldFile, generatedFile, patchFile, function (result) {
console.log('patch:' + String(result).padStart(4) + '%');
});
}

asyncCall();
