passport-gitlab2

The original Passport-GitLab module has not been maintained for a long time. Due to the unclear license situation and issues in the code, this library was rewritten based on Passport-Facebook and published under the MIT license.

Passport strategy for authenticating with GitLab using the OAuth2 authentication provider service.

This module lets you authenticate using GitLab in your Node.js applications. By plugging into Passport, GitLab authentication can be easily and unobtrusively integrated into any application or framework that supports Connect-style middleware, including Express.

Install

$ npm install passport-gitlab2

Usage

Passport-GitLab requires GitLab 9.0.0 or higher to work. Before using the OAuth2 authentication provider service, you have register a new application in your user profile or in the administrator portal. GitLab will then issue an application ID and a secret, which need to be provided to the strategy. You will also need to configure a redirect URI which matches the route in your application.

Configure Strategy

The GitLab authentication strategy authenticates users using a GitLab account and OAuth 2.0 tokens. The app ID and secret obtained when creating an application are supplied as options when creating the strategy. The strategy also requires a verify callback, which receives the access token and optional refresh token, as well as profile which contains the authenticated user's GitLab profile. The verify callback must call cb providing a user to complete authentication.

passport.use(new GitLabStrategy({
    clientID: GITLAB_APP_ID,
    clientSecret: GITLAB_APP_SECRET,
    callbackURL: "http://localhost:3000/auth/gitlab/callback"
  },
  function(accessToken, refreshToken, profile, cb) {
    User.findOrCreate({gitlabId: profile.id}, function (err, user) {
      return cb(err, user);
    });
  }
));

Authenticate Requests

Use passport.authenticate(), specifying the 'gitlab' strategy, to authenticate requests.

For example, as route middleware in an Express application:

app.get('/auth/gitlab', passport.authenticate('gitlab'));
 
app.get('/auth/gitlab/callback',
  passport.authenticate('gitlab', {
    failureRedirect: '/login'
  }),
  function(req, res) {
    // Successful authentication, redirect home.
    res.redirect('/');
  });

FAQ

How do I use my own GitLab instance rather than gitlab.com?

Passport-GitLab automatically uses GitLab.com as authentication endpoint when not configured otherwise. You can use the baseURL parameter to point to any other GitLab instance as following:

new GitLabStrategy({
  clientID: GITLAB_APP_ID,
  clientSecret: GITLAB_APP_SECRET,
  callbackURL: "http://localhost:3000/auth/gitlab/callback",
  baseURL: "https://gitlab.example.com/"
}), ...)

All URLs (e.g. token-url, authorization-url, profile-url) are automatically adapted to utilize the configured instance. You can of course overwrite all URLs manually if needed.

How do I change permissions / scope when obtaining a user profile?

GitLab supports multiple scopes at the moment like read_user and api. By default, the read_user scope is used. Changing the OAuth2 scope to api works as following:

app.get('/auth/gitlab',
  passport.authenticate('gitlab', {
    scope: ['api']
  }));

More information can be found in the official GitLab documentation.
