Node.js libgit2 bindings

v0.0.74 Build

Maintained by Tim Branyen @tbranyen and Michael Robinson @codeofinterest, with help from awesome contributors!


Nodegit aims to eventually provide native asynchronous bindings for as much of libgit2 as possible, but we can't do it alone!

We welcome pull requests, but please pay attention to the following: whether your lovely code fixes a bug or adds a new feature, please include unit tests that either prove the bug is fixed, or that your new feature works as expected. See running tests

Unit tests are what makes the Node event loop go around.

Building and installing


To install nodegit you need Node.js, python and cmake. To run unit tests you will need to have git installed and accessible from your PATH to fetch any vendor/ addons.

Easy install (Recommended)

This will install and configure everything you need to use nodegit.

$ npm install nodegit

Mac OS X/Linux/Unix

Install nodegit by cloning source from GitHub and running node install:

$ git clone git://
$ cd nodegit
$ node install

*Updating to a new version*

$ git pull
$ node install

Windows via Cygwin

nodegit has been compiled and tested to work with the setup required to build and run Node.js itself.

Instructions on compiling Node.js on a Windows platform can be found here:

API Example Usage

Git Log Emulation

Convenience API

var git = require("nodegit");

// Read a repository
var git = require('nodegit');

// nodegit follows the error, values ... callback argument convention
git.repo('.git', function(error, repo) {
  if (error) { throw error; }

  // Use the master branch
  repo.branch('master', function(error, branch) {
    if (error) { throw error; }

    // Print out `git log` emulation for each commit in the branch's history
    branch.history().on('commit', function(error, commit) {
      console.log('commit ' + commit.sha);
      console.log( + '<' + + '>');
      console.log(new Date(commit.time * 1000));


var git = require('nodegit').raw;

// Create instance of Repo constructor
var repo = new git.Repo();

// Read a repository'.git', function(err) {
  // Err is an integer, success is 0, use strError for string representation
  if (err) {
    var error = new git.Error();
    throw error.strError(err);

  // Create instance of Ref constructor with this repository
  var ref = new git.Ref(repo);

  // Find the master branch
  repo.lookupRef(ref, '/refs/heads/master', function(err) {
    if (err) {
      var error = new git.Error();
      throw error.strError(err);

    // Create instance of Commit constructor with this repository
    var commit = new git.Commit(repo);

    // Create instance of Oid constructor
    var oid = new git.Oid();

    // Set the oid constructor internal reference to this branch reference

    // Lookup the commit for this oid
    commit.lookup(oid, function(err) {
      if (err) {
        var error = new git.Error();
        throw error.strError(err);

      // Create instance of RevWalk constructor with this repository
      var revwalk = new git.RevWalk(repo);

      // Push the commit as the start to walk

      // Recursive walk
      function walk() {
        // Each revision walk iteration yields a commit
        var revisionCommit = new git.Commit(repo);, function(err) {
          // Finish recursion once no more revision commits are left
          if (err) { return; }

          // Create instance of Oid for sha
          var oid = new git.Oid();

          // Set oid to the revision commit

          // Create instance of Sig for author
          var author = new git.Sig();

          // Set the author to the revision commit author

          // Convert timestamp to milliseconds and set new Date object
          var time = new Date( revisionCommit.time() * 1000 );

          // Print out `git log` emulation
          console.log(oid.toString( 40 ));
          console.log( + '<' + + '>');

          // Recurse!

      // Initiate recursion

Running tests

nodegit library code is written adhering to a modified JSHint. Run these checks with make lint in the project root.

To run unit tests ensure to update the submodules with git submodule update --init and install the development dependencies nodeunit and rimraf with npm install.

Then simply run npm test in the project root.


Recent documentation may be found here: nodegit documentation

nodegit native and library code is documented to be built with Natural Docs.

To create the documentation, cd into the nodegit dir and run the following: $ cd nodegit $ make doc

The documentation will then generate in the doc/ subfolder as HTML.

Getting involved

If you find this project of interest, please document all issues and fork if you feel you can provide a patch. Testing is of huge importance; by simply running the unit tests on your system and reporting issues you can contribute!

Before submitting a pull request, please ensure both that you've added unit tests to cover your shiny new code, and that all unit tests and lint checks pass.

Something went wrong with that request. Please try again.
