passport-discord

The author of the original repo is no longer maintaining the package. This is a fork of the original passport-discord.

Passport strategy for authentication with Discord through the OAuth 2.0 API.

Before using this strategy, it is strongly recommended that you read through the official docs page here, especially about the scopes and understand how the auth works.

Changes compared to parent library

Ability to configure disable_guild_select, and guild_id parameters when authenticating bots
Fixed bug causing callback to be called twice when get guilds request failed
Fixed bug causing the response to be sent twice on error

Usage

npm install passport-discord --save

Configure Strategy

The Discord authentication strategy authenticates users via a Discord user account and OAuth 2.0 token(s). A Discord API client ID, secret and redirect URL must be supplied when using this strategy. The strategy also requires a verify callback, which receives the access token and an optional refresh token, as well as a profile which contains the authenticated Discord user's profile. The verify callback must also call cb providing a user to complete the authentication.

var DiscordStrategy = require('passport-discord').Strategy;

var scopes = ['identify', 'email', 'guilds', 'guilds.join'];

passport.use(new DiscordStrategy({
    clientID: 'id',
    clientSecret: 'secret',
    callbackURL: 'callbackURL',
    scope: scopes
},
function(accessToken, refreshToken, profile, cb) {
    User.findOrCreate({ discordId: profile.id }, function(err, user) {
        return cb(err, user);
    });
}));

Authentication Requests

Use passport.authenticate(), and specify the 'discord' strategy to authenticate requests.

For example, as a route middleware in an Express app:

app.get('/auth/discord', passport.authenticate('discord'));
app.get('/auth/discord/callback', passport.authenticate('discord', {
    failureRedirect: '/'
}), function(req, res) {
    res.redirect('/secretstuff') // Successful auth
});

Bot Authentication

If using the bot scope, the permissions option can be set to indicate specific permissions your bot needs on the server (permission codes):

app.get("/auth/discord", passport.authenticate("discord", { permissions: 66321471 }));

You can also determine the default guild by passing in a Guild Discord ID and toggle the appearance of the guilds dropdown,

app.get("/auth/discord", passport.authenticate("discord", { disable_guild_select: true, guild_id: 'someid' }));

Refresh Token Usage

In some use cases where the profile may be fetched more than once or you want to keep the user authenticated, refresh tokens may wish to be used. A package such as passport-oauth2-refresh can assist in doing this.

Example:

npm install passport-oauth2-refresh --save

var passport = require('passport')
var DiscordStrategy = require('passport-discord').Strategy
  , refresh = require('passport-oauth2-refresh');

var discordStrat = new DiscordStrategy({
    clientID: 'id',
    clientSecret: 'secret',
    callbackURL: 'callbackURL'
},
function(accessToken, refreshToken, profile, cb) {
    profile.refreshToken = refreshToken; // store this for later refreshes
    User.findOrCreate({ discordId: profile.id }, function(err, user) {
        if (err)
            return done(err);

        return cb(err, user);
    });
});

passport.use(discordStrat);
refresh.use(discordStrat);

... then if we require refreshing when fetching an update or something ...

refresh.requestNewAccessToken('discord', profile.refreshToken, function(err, accessToken, refreshToken) {
    if (err)
        throw; // boys, we have an error here.
    
    profile.accessToken = accessToken; // store this new one for our new requests!
});

Examples

An Express server example can be found in the /example directory. Be sure to npm install in that directory to get the dependencies.
