The Slack authentication strategy authenticates users using a Slack
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.
passport.use(new SlackStrategy({
clientID: CLIENT_ID,
clientSecret: CLIENT_SECRET,
skipUserProfile: false, // default
scope: ['identity.basic', 'identity.email', 'identity.avatar', 'identity.team'] // default
},
(accessToken, refreshToken, profile, done) => {
// optionally persist user data into a database
done(null, profile);
}
));
Use passport.authorize()
(or passport.authenticate()
if you want to authenticate with Slack and affect req.user
and user session), specifying the 'slack'
strategy, to
authenticate requests.
For example, as route middleware in an Express application:
app.get('/auth/slack', passport.authorize('slack'));
app.get('/auth/slack/callback',
passport.authorize('slack', { failureRedirect: '/login' }),
(req, res) => res.redirect('/') // Successful authentication, redirect home.
);
By default passport-slack strategy will try to retrieve all user identity from Slack using the default scopes of identity.basic
, identity.email
, identity.avatar
, and identity.team
. To override these, set the scope
parameter to an array of scopes.
passport.use(new SlackStrategy({
clientID: CLIENT_ID,
clientSecret: CLIENT_SECRET,
scope: ['identity.basic', 'channels:read', 'chat:write:user']
}, () => { });
If you just need an access token and not user profile data, you can avoid getting profile info by setting skipUserProfile
to true.
passport.use(new SlackStrategy({
clientID: CLIENT_ID,
clientSecret: CLIENT_SECRET,
scope: ['incoming-webhook'],
skipUserProfile: true
}, () => { });
