Gatekeeper

Because of some security-related limitations, Github prevents you from implementing the OAuth Web Application Flow on a client-side only application.

This is a real bummer. So we built Gatekeeper, which is the missing piece you need in order to make it work.

Gatekeeper works well with Github.js, which helps you access the Github API from the browser. Gatekeeper is free to use under the MIT license.

New Release

🎉 We are currently working on releasing a new major version of gatekeeper. You can join the discussion and get involved by following this issue. 🎉

API

GET http://localhost:9999/authenticate/TEMPORARY_CODE

OAuth Steps

Also see the documentation on Github.

Redirect users to request GitHub access.

GET https://github.com/login/oauth/authorize

GitHub redirects back to your site including a temporary code you need for the next step.

You can grab it like so:
```
var code = window.location.href.match(/\?code=(.*)/)[1];
```

Request the actual token using your instance of Gatekeeper, which knows your client_secret.

$.getJSON('http://localhost:9999/authenticate/'+code, function(data) {
  console.log(data.token);
});

Setup your Gatekeeper

Clone it

git clone git@github.com:prose/gatekeeper.git

Install Dependencies
```
cd gatekeeper && npm install
```

Adjust config.json

{
  "oauth_client_id": "GITHUB_APPLICATION_CLIENT_ID",
  "oauth_client_secret": "GITHUB_APPLICATION_CLIENT_SECRET",
  "oauth_host": "github.com",
  "oauth_port": 443,
  "oauth_path": "/login/oauth/access_token",
  "oauth_method": "POST",
  "port": 9999
}

You can also set environment variables to override the settings if you don't want Git to track your adjusted config.json file. Just use UPPER_CASE keys.

Serve it
```
$ node index.js
```
