Sinatra based API for Git repositories, powered by Grit

GritHttp

GritHttp is a Sinatra application that provides a web JSON-based API to git repositories.

Git support is powered by Grit ruby library.

The main purpose of this application is to serve git objects data via simple api interface. If you're hosting git repositories on your own server this tool might be useful to provide an access to a third-party apps.

Installation

The current state is not stable yet, but you can install this application by cloning the official git repo:

$ git clone git://github.com/sosedoff/grit-http.git
$ cd grit-http
$ bundle install

Configuration

Be default all configuration files are located in config/ folder under the app's root path.

There is a sample config file - config.yml.sample - where you can find more details and possible options.

Sample configuration:

protection: true
cache: false
api_keys:
  - "SAMPLE_API_KEY"
repositories:
  name: /path/to/repository

Options:

• protection - Enable/disable API keys usage.
• cache - Enable/disable caching
• api_keys - List of your API keys. You can add as many as you want
• repositories - List of full paths to your repositories. Each repository should have an alias, which is going to be used in requests.

Deployment

The easiest way to get it up and running is to use Thin:

$ cd grit-http
$ thin start -e production

Passenger Phusion + Nginx

Sample configuration:

server {
  listen 80;
  server_name git.yourhost.com
  charset utf-8;
  passenger_enabled on;
  rack_env production;
  root /path/to/app/public;
}

Passenger Phusion + Nginx (Subroute)

If you already have an application deployed with passenger, its really easy to add another subroute to the app.

Just symlink grit-http's public folder into your current app's public folder. Name of this folder should be the same as you use in subroute.

server {
  listen 80;
  server_name yourhost.com
  charset utf-8;
  passenger_enabled on;
  passenger_base_uri /git;
  rails_env production;
  root /path/to/your/existing/app;
}

Unicorn + Nginx

This section is coming soon.

API Usage

API allowes you to make only GET requests, it is a read-only resource. It returns each response in JSON mode and UTF-8 encoding (except raw method).

Each response (failed and successful) from server has a structure:

{
  "result": true,
  "data": {}
}

Fields:

• result - Indicates if request was successful. (true/false)
• data - Primary container for api response.

If configuration option "protection" is set to true, all requests should have a "api_key" parameter added.

Unprotected request:

curl -i "http://yourhost.com/"

Protected request:

curl -i "http://yourhost.com/?api_key=KEY"
