The easiest way to create an uncomplicated private or public git server, that's up to you.

UltraGit is a fast and easy to deploy git server written in Node.js. It uses SQLite as database to store the users information and permissions.

npm install ultragit

It's as easy as this:

const rugs = require('ultragit')

const ugs = new rugs.UltraGitServer()
const DB_PATH = '/opt/GIT/DB'
const REPOS_PATH = '/opt/GIT/repos'
const PORT = 1221

ugs.init(DB_PATH, REPOS_PATH, PORT, () => {
    console.log('UltraGit running at http://localhost:'   PORT)
})

Finally, run it, and you're ready to go.

node index.js
