This library provides a very simple wrapper around the git binary.

Getting Started

Install the module with: npm install git-exec


The library is used by constructing an object which represents a git repository on the system.

The majority of the interaction involves an exec() method which is invoked on instances of such objects. This method is relatively stupid in that we do not try to parse the output or validate commands invoked.

However, we do take care to provide a means to both init / clone git repositories and we set the working directory correctly such that further git commands execute in the correct context.


This method will construct a repo object at the specified directory.


These methods will return a repo object on success as the first argument to the callback passed to them or null on error.

function callback(repo) {
  if (repo !== null) {
    // valid repo
  } else {
    // an error occurred


Cloning a remote repository and checkout of origin/dev

var Git = require('git-exec');
Git.clone('a-repo.git', 'dir', function(repo) {
  // NOTE the callback is given a reference to the git repository

  repo.exec('checkout', ['-t origin/dev'], function() {
    // ... callback to execute after branch checkout

Intialising a local repository in CWD

var Git = require('git-exec');
Git.init('my-new-repo', null, function(repo) {
  // ... operations on repo object

Intialising a local repository at given path

var Git = require('git-exec');
Git.init(null, '/path/to/repo', function(repo) {
  // ... operations on repo object

As an alternative, init also supports a named repo at a specific path. Thus for a repo named 'my-new-repo' at '/path/to' such that the full path to the repo is /path/to/my-new-repo call init as follows:

var Git = require('git-exec');
Git.init('my-new-repo', '/path/to', function(repo) {
  // ... operations on repo object

Using a local git repository

var Git = require('git-exec');
var repo = new Git('./path/to/repo');

repo.exec('pull', null, function(err, stdout) {
  // ... callback to execute after git pull

Or alternatively, to instantly create a repo and perform some operation:

require('git-exec').repo('./path/to/repo').exec('branch', ['dev'], function() {
  // ... callback to execute


In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using grunt.
