An binary diff and patch library based on bsdiff algorithm for NodeJS (Windows, Mac, Linux)
If you find this package useful, please don't forget to star ⭐️ the repo, as this will help to promote the project.
Install as a dependency for your project (need python 3.x):
npm i bsdiff-node
constbsdiff=require('bsdiff-node');bsdiff.diff(oldFile,newFile,patchFile,function(result,err){});// Asyncbsdiff.patch(oldfile,newfile,patchfile,function(result,err){});// Asyncbsdiff.diffSync(oldFile,newFile,patchFile);// Syncbsdiff.patchSync(oldfile,newfile,patchfile);// Sync
For example:
constpath=require('path');constoldFile=path.join(__dirname,'resources/react-0.3-stable.zip');constnewFile=path.join(__dirname,'resources/react-0.4-stable.zip');constpatchFile=path.join(__dirname,'resources/react.patch');constgeneratedFile=path.join(__dirname,'resources/react-generated.zip');asyncfunctionasyncCall(){awaitbsdiff.diff(oldFile,newFile,patchFile,function(result){console.log('diff:'+String(result).padStart(4)+'%');});awaitbsdiff.patch(oldFile,generatedFile,patchFile,function(result){console.log('patch:'+String(result).padStart(4)+'%');});}asyncCall();
The original algorithm and implementation was developed by Colin Percival. Thealgorithm is detailed in his paper,Naïve Differences of Executable Code. For more information, visit hiswebsite athttp://www.daemonology.net/bsdiff/.
