tl;dr Use the Node.js package @superfaceai/passport-twitter-oauth2 to handle user authentication with Twitter's v2 API and Passport.js.
Let's create a simple Express server with Passport.js to show the authentication flow in action. Passport requires some session handling mechanism, usually through express-session. I will also use the dotenv package to load the credentials from .env file to process.environment object.
Passport needs to be initialized as middleware as well. And it requires a session middleware for storing state and user data. The most common session middleware is express-session.
Passport.js isn't limited to just Express, you can use our strategy with other frameworks with Passport compatibility like NestJS, Fastify, or Koa.

With the obtained access token, you can start integrating Twitter's API. Check out our twitter-demo repository with CLI scripts showing how to list followers, lookup posts by hashtag, or publish a tweet.
We also have a bit more complex social-media-demo which demonstrates authentication and integrations with Facebook, Instagram, LinkedIn, and Twitter.
This module lets you authenticate using Twitter in your Node.js applications By plugging into Passport, Twitter authentication can be integrated into any application or framework that supports Connect-style middleware, including Express.
To start using Twitter API, you need to register for a developer account (including phone number verification). Once you register, you will be prompted to create the first application. You will immediately receive API Key and API Key Secret – but ignore them, since these are only for OAuth 1.0. Instead, go to your project's dashboard, there go to the App Settings of the only application you created. In application settings, find User authentication settings and click Set up.
