@qgisk/passport-discord v1.0.0

passport-discord

The original author(s) no longer seemed to maintain the package, This is a rewrite of both the originals in a more 'modern' fashion.

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.

Is this much different than the other 2?

Nope, only thing I've added is a seperate error when being rate limited by Discord. ( Note: This does not kill the auth process, when being rate limited on scopes. The 'scope' will simply be empty. ).

The rest works the same. ( I hope ;p )

Why?

tbh I was just bored.

Installation

npm install @qgisk/passport-discord --save # or pnpm add @qgisk/passport-discord

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.

const Strategy = require('@qgisk/passport-discord').Strategy;

const scopes = ["identify", "email", "connections", "guilds", "guilds.join"];
const prompt = "consent";

passport.serializeUser(function (user, done) {
  done(null, user);
});
passport.deserializeUser(function (obj, done) {
  done(null, obj);
});

passport.use(new Strategy({
    clientID: 'id',
    clientSecret: 'secret',
    callbackURL: 'callbackURL',
    scope: scopes,
    prompt: prompt,
},
(accessToken, refreshToken, profile, cb) => {
    User.findOrCreate({ discordId: profile.id }, (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: '/' // Failure
}), (req, res) => {
    res.redirect('/profile') // Success
});

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: 'id' }));

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 # or pnpm add passport-oauth2-refresh

const passport = require('passport')
const DiscordStrategy = require('passport-discord').Strategy
const Refresh = require('passport-oauth2-refresh');

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

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

passport.use(discordStrategy);
refresh.use(discordStrategy);

Then when refreshing the token

refresh.requestNewAccessToken('discord', profile.refreshToken, (err, accessToken, refreshToken) => {
    if (err)
        throw Error(error);
    
    profile.accessToken = accessToken;  // Store this
});

Examples

The examples can be found in the /examples directory.

Be sure to npm i or pnpm i

Theres an example for a simple Express setup, and one with vite-plugin-ssr ( This one is with Vue but can be easily adapted).
