Twitch authentication strategy using Helix for Passport. Supports the April 2020 Twitch changes!

Twitch is a trademark or registered trademark of Twitch Interactive, Inc. in the U.S. and/or other countries. "passport-twitch" is not operated by, sponsored by, or affiliated with Twitch Interactive, Inc. in any way.

Passport strategy for authenticating with Twitch using OAuth 2.0 on Helix (the New Twitch API).

This module lets you authenticate using Twitch in your Node.js applications. By plugging into Passport, Twitch authentication can be easily and unobtrusively integrated into any application or framework that supports Connect style middleware, including Express and Koa.

Prerequisites

• node >=10

Install

yarn install @hewmen/passport-twitch

Example

The Twitch OAuth 2.0 authentication strategy authenticates users using a Twitch 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.

Configure Strategy

import passport from "passport";
import { Strategy as TwitchStrategy, Scope } from "@hewmen/passport-twitch";

const onStrategyCallback = (accessToken: string, refreshToken: string, profile: T, done: (err: Error | null, user?: UserType) => void) => {
    User.findOrCreate({twitchId: profile.id}, (err, user) => {
        done(err, user);
    })
}

const myStrategy = new TwitchStrategy({
    clientID: "twitch_client_id",
    clientSecret: "twitch_client_secret",
    callbackURL: "http://localhost:3000/auth/twitch/callback",
    scope: [Scope.UserReadEmail]
}, onStrategyCallback);

passport.use(myStrategy);

Authenticate Requests

Use passport.authenticate(), specifying the "twitch" strategy, to authenticate requests.

For example, as route middleware in an Express application:

import express from "express";

const app = express();

app.get("/auth/twitch", passport.authenticate("twitch"));
app.get("/auth/twitch/callback", passport.authenticate("twitch", { failureRedirect: "/" }), (req, res) => {
    res.redirect("/");
});

Optionally, the forceVerify option can be set to true to indicate that the user should be re-prompted for authorization:

app.get("/auth/twitch", passport.authenticate("twitch", {forceVerify: true}));

Complete Example:

import express from "express";
import bodyParser from "body-parser";
import cookieSession from "cookie-session";
import passport from "passport";
import { Strategy as TwitchStrategy, Scope } from "@hewmen/passport-twitch";

const app = express();

app.set("views", "./views");
app.set("view engine", "ejs");

// Middlewares
app.use(bodyParser.urlencoded({ extended: true }));
app.use(cookieParser());
app.use(cookieSession({secret:"somesecrettokenhere"}));
app.use(passport.initialize());
app.use(express.static("./public"));

passport.use(new TwitchStrategy({
    clientID: "098f6bcd4621d373cade4e832627b4f6",
    clientSecret: "4eb20288afaed97e82bde371260db8d8",
    callbackURL: "http://localhost:3000/auth/twitch/callback",
    scope: [Scope.UserReadEmail]
  },
  (accessToken, refreshToken, profile, done) => {
    // Suppose we are using mongo..
    User.findOrCreate({ twitchId: profile.id }, function (err, user) {
      done(err, user);
    });
  }
));

passport.serializeUser((user, done) => {
    done(null, user);
});

passport.deserializeUser((user, done) => {
    done(null, user);
});

app.get("/", (req, res) => {
    res.render("index");
});

app.get("/auth/twitch", passport.authenticate("twitch"));
app.get("/auth/twitch/callback", passport.authenticate("twitch", { failureRedirect: "/" }), (req, res) => {
    // Successful authentication, redirect home.
    res.redirect("/");
});

app.listen(3000);
