Simple Git

A light weight interface for running git commands in any node.js application.

Installation

Easiest through npm: npm install simple-git

Dependencies

Relies on git already having been installed on the system, and that it can be called using the command git.

Usage

Include into your app using:

var simpleGit = require('simple-git')( workingDirPath );

where the workingDirPath is optional, defaulting to the current directory.

Use simpleGit by chaining any of its functions together. Each function accepts an optional final argument which will be called when that step has been completed. When it is called it has two arguments - firstly an error object (or null when no error occurred) and secondly the data generated by that call.

.clone(repoPath, localPath, handlerFn) clone a remote repo at repoPath to a local directory at localPath

.pull(remote, branch, handlerFn) pull all updates from the repo ('origin'/'master')

.fetch(remote, branch, handlerFn) update the local working copy database with changes from a remote repo

.fetch(handlerFn) update the local working copy database with changes from the default remote repo and branch

.tags(handlerFn) list all tags

.checkout(checkoutWhat, handlerFn) checks out the supplied tag, revision or branch

.checkoutLatestTag(handlerFn) convenience method to pull then checkout the latest tag

.add([fileA, ...], handlerFn) adds one or more files to be under source control

.commit(message, handlerFn) commits changes in the current working directory with the supplied message

.commit(message, [fileA, ...], handlerFn) commits changes on the named files with the supplied message

.push(remote, branch, handlerFn) pushes to a named remote and named branch

.rm([fileA, ...], handlerFn) removes any number of files from source control

.rmKeepLocal([fileA, ...], handlerFn) removes files from source control but leaves them on disk

.addRemote(name, repo, handlerFn) adds a new named remote to be tracked as name at the path repo

.removeRemote(name, handlerFn) removes the named remote

.listRemote([args], handlerFn) lists remote repositories - there are so many optional arguments in the underlying git ls-remote call, just supply any you want to use as the optional args string.

Examples

// update repo and get a list of tags
require('simple-git')(__dirname + '/some-repo')
     .pull()
     .tags(function(err, tags) {
        console.log("Latest available tag: %s", tags.latest);
     });


// update repo and when there are changes, restart the app
require('simple-git')()
     .pull(function(err, update) {
        if(update && update.summary.changes) {
           require('child_process').exec('npm restart');
        }
     });


// starting a new repo
require('simple-git')()
     .init()
     .add('./*')
     .commit("first commit!")
     .addRemote('origin', 'https://github.com/user/repo.git')
     .push('origin', 'master');
