github-auth

A middleware for github authentication.

github-auth

A middleware for github authentication.

You can install this module with npm

npm install github-auth

You can use the middleware on a connect/express app like this.

var githubAuth = require('github-auth');
 
var config = {
    team: 'some-team',
    organization: 'my-company',
    autologin: true // This automatically redirects you to github to login. 
};
var gh = githubAuth('github app id', 'github app secret', config);
app.use(gh.authenticate);

That will validate that the user belongs to the 'some-team' team of the 'my-company' organization on github.

You can also use a whitelist of users, like this.

var githubAuth = require('github-auth');
 
var config = {
    users: ['sorribas', 'mafintosh', 'octocat']
};
var gh = githubAuth('github app id', 'github app secret', config);
app.use(gh.authenticate);

The authenticate middleware sets the req.github property to an object which contains user and authenticated. That way you can decide what to do with unauthenticated users (redeirect them to the login page for example). If the req.github object is not present it means that the user has not tried to login, so you should redirect them to the github login page which is on gh.loginUrl

You can also use the .login middleware which redirects you to the github oauth login page.

app.get('ghlohin', gh.login);

To get the users in a team with the github API you need the full write access on the user profile, which is not really nice. You can avoid this by passing some github credentials with access to the team to the module so it uses basic HTTP auth.

var githubAuth = require('github-auth');
 
var config = {
    team: 'some-team',
    organization: 'my-company',
    credentials: {
        user: 'myghuser',
        pass: 'mypass'
    }
};
app.use(githubAuth('github app id', 'github app secret', config).authenticate);
 

Also, you don't have to use this module with connect or express. You could just use it in your regular node http server like this.

 
http.createServer(function(requestresponse) {
    var config = {
        team: 'some-team',
        organization: 'my-company'
    };
    githubAuth('github app id', 'github app secret', config).authenticate(request, response, function(err) {
        if(!err) return response.end(err);
 
        // your http code here 
    });
});
 
  • maxAge: Sets the maxAge of the authentication cookie (milliseconds). Defaults to set a session cookie.
  • secret: The module uses a random secret to sign the authentication cookie. If you want to manage this yourself you can do it by providing it as part of the config.

Examples

There is an example in the examples folder using Express 3. To run it you need to install express 3.x and github-auth.
