passport-mastodon-autoregister

Passport strategy for authentication with any Mastodon instance through OAuth 2.0. This strategy creates a oAuth App on the Mastodon instance and passes the required details to passport-oauth2.

Installation

npm install passport-mastodon-autoregister

Usage

Configure Strategy

It's important to know you cannot pass the same arguments to this strategy. If you want to pass arguments like passReqToCallback to the created passport-oauth2 strategy, you can pass them under the oAuthOptions key.

passport.use(new MastodonStrategy({

    clientName: 'Mastodon Test App',
    scopes: ['read', 'write'],
    redirectUri: 'https://example.org/auth/callback',

    oAuthOptions: {}

}, function(accessToken, refreshToken, profile, cb) {
    return cb(null, profile);
}, function (instanceUrl, done) {

    let provider = storage.get(instanceUrl);
    provider ? done(provider.clientKey, provider.clientSecret) : this.createApplication(instanceUrl, (err, provider) => {

        if(err) {
            console.error('Error creating application', err);
            return err;
        }

        storage.set(instanceUrl, {
            clientKey: provider.client_id,
            clientSecret: provider.client_secret
        });
        done(provider.client_id, provider.client_secret);
    });
}));

This strategy requires a second callback function to create the oAuth App on the Mastodon instance. You should store the clientKey and clientSecret to avoid creating a new oAuth App on every request.

Authenticate Requests

Use passport.authenticate(), specifying the 'mastodon-autoregister' strategy, to authenticate requests.

For example, as route middleware in an Express application:

app.get('/auth',
  passport.authenticate('mastodon-autoregister'));

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

Example

An example implementation can be found in the example.js file.
