Spotify authentication strategy for Passport.
npm install passport-spotifyPassport strategy for authenticating with Spotify
using the OAuth 2.0 API.
This module lets you authenticate using Spotify in your Node.js applications.
By plugging into Passport, Spotify authentication can be easily and
unobtrusively integrated into any application or framework that supports
Connect-style middleware, including
Express.
For more information about Spotify's OAuth 2.0 implementation, check their
Web API Authorization Guide.
$ npm install passport-spotify
The Spotify authentication strategy authenticates users using a Spotify account
and OAuth 2.0 tokens. The strategy requires a verify callback, which accepts
these credentials and calls done providing a user, as well as options
specifying a client ID, client secret, and callback URL.
``javascript
const SpotifyStrategy = require('passport-spotify').Strategy;
passport.use(
new SpotifyStrategy(
{
clientID: client_id,
clientSecret: client_secret,
callbackURL: 'http://localhost:8888/auth/spotify/callback'
},
function(accessToken, refreshToken, expires_in, profile, done) {
User.findOrCreate({ spotifyId: profile.id }, function(err, user) {
return done(err, user);
});
}
)
);
`
Use passport.authenticate(), specifying the 'spotify' strategy, to
authenticate requests.
For example, as route middleware in an Express
application:
`javascript
app.get('/auth/spotify', passport.authenticate('spotify'));
app.get(
'/auth/spotify/callback',
passport.authenticate('spotify', { failureRedirect: '/login' }),
function(req, res) {
// Successful authentication, redirect home.
res.redirect('/');
}
);
`
Depending on the data you want to fetch, you may want to specify custom scopes. For more information about scopes in the Spotify Web API check their developer site.
By default, no scope is passed. That means that you won't fetch information such as display name, picture or email. You can get those by using these scopes:
- user-read-email: Returns the email address of the user on Spotify, if it exists.user-read-private
- : Returns private information about the user such as display name and picture, if they are set.
You can specify the parameters in the authenticate call:
`javascript`
app.get(
'/auth/spotify',
passport.authenticate('spotify', {
scope: ['user-read-email', 'user-read-private']
})
);
You can force the login dialog using the showDialog parameter when authenticating:
`javascript``
app.get(
'/auth/spotify',
passport.authenticate('spotify', {
scope: ['user-read-email', 'user-read-private'],
showDialog: true
})
);
For a complete, working example, refer to the login example.
