How to build Login with GitLab using Node and WorkOS

To add Login with GitLab functionality to an app using Node and WorkOS, developers need to follow a series of steps. First, they must install the WorkOS Node SDK and set environment variables for authentication. Next, they need to configure a connection between their app and GitLab OAuth by creating an application on GitLab's side and copying specific values from the WorkOS dashboard. After that, they have to provide client credentials to WorkOS, configure a redirect URI, and set up the frontend to display a login link. Finally, they must implement backend logic using AuthKit to handle user authentication, extract authorization codes, exchange them for tokens, and manage user sessions securely. This tutorial provides a comprehensive guide for integrating Login with GitLab into an app using Node and WorkOS, but some steps may become outdated as products evolve.
