A Node.js and Express web application with advanced user registration and authentication via FusionAuth is built. The application includes a custom registration form, consent options for marketing preferences, and self-service options for users to update their profile and consent permissions. A Docker setup is used to install and configure FusionAuth. The application uses Passport and the FusionAuth Typescript client to handle authentication and identity management. The Express app has routes for login, registration, and a members-only area that displays user information and allows them to update it via a custom self-service form. The app demonstrates how to implement advanced user consent management with FusionAuth.
