# Deploy and Host Flask Authentication & User Management on Railway

Flask Authentication & User Management is a single-file Flask API providing JWT-based auth, user registration, login, profile management, admin controls, and password handling. It ships with an interactive demo UI for testing all endpoints live, supports SQLite locally and Postgres in production, and is ready to deploy with one click.

## About Hosting this app

Hosting Flask Authentication & User Management involves running a Gunicorn-served Flask application connected to a PostgreSQL database. Railway auto-detects the Python buildpack via Nixpacks, installs dependencies from `requirements.txt`, and runs the start command defined in the `Procfile`. The app reads `DATABASE_URL` directly from the Railway-provisioned Postgres plugin, automatically converting the connection string to SQLAlchemy-compatible format. A `SECRET_KEY` environment variable must be set for JWT token signing. The included health check endpoint at `/api/health` enables Railway's deployment monitoring. The interactive demo UI is served at the root path, giving immediate visual confirmation that the deploy succeeded.

## Common Use Cases

- Backend auth service for apps needing user registration, login, and JWT-protected API routes
- Starter template for building full-stack apps that require user accounts, role-based access, and admin dashboards
- Educational reference project for beginners learning how to implement authentication, password hashing, and REST APIs with Flask

## Dependencies for Flask Authentication & User Management Hosting

- Python 3.10+
- PostgreSQL (provisioned as a Railway plugin)

### Deployment Dependencies

- [Flask](https://flask.palletsprojects.com/) — Web framework
- [Flask-SQLAlchemy](https://flask-sqlalchemy.readthedocs.io/) — ORM and database integration
- [PyJWT](https://pyjwt.readthedocs.io/) — JSON Web Token authentication
- [psycopg2-binary](https://www.psycopg.org/) — PostgreSQL adapter
- [Gunicorn](https://gunicorn.org/) — Production WSGI server
- [Flask-CORS](https://flask-cors.readthedocs.io/) — Cross-origin request handling

### Implementation Details

The app uses a single `main.py` file. JWT tokens are issued on registration and login, stored as HTTP-only cookies and also returned in JSON for `Authorization: Bearer` header usage. The first registered user is automatically promoted to admin. Admin routes support paginated user listing, search, activation toggling, and deletion. Password hashing uses Werkzeug's `generate_password_hash` with default PBKDF2-SHA256. Railway's `postgres://` URLs are auto-converted to `postgresql://` for SQLAlchemy compatibility.
