Deploy and Host FastUI ToDo App on Railway

A pure-Python todo application built with FastUI and FastAPI. Manage tasks with add, toggle, and delete actions, filter by status, and enjoy a reactive React-powered UI — all without writing any JavaScript. Ideal for learning FastUI or as a starter template.

About Hosting FastUI ToDo App

Deploying FastUI ToDo App on Railway requires no special infrastructure. The app runs as a single Python process serving both the FastAPI backend and the prebuilt FastUI React frontend from one file. Railway auto-detects the Python environment via Nixpacks, installs dependencies from requirements.txt, and starts the Uvicorn ASGI server using the included Procfile. No database, build step, or Node.js toolchain is needed — the app is fully self-contained and ready to serve immediately after deployment.

Common Use Cases

Learning how FastUI works by exploring and modifying a working deployed example
Teaching Python web development without requiring students to learn JavaScript or React
Using as a starter template to build more complex FastUI applications on Railway

Dependencies for FastUI ToDo App Hosting

Python 3.10+
FastAPI (web framework)
FastUI >= 0.9.0 (declarative UI components via Pydantic)
Uvicorn (ASGI server)
python-multipart (form data parsing)

Deployment Dependencies

Implementation Details

The entire app is a single app.py. FastUI components are Pydantic models returned as JSON — the prebuilt React SPA fetches /api/ routes and renders them automatically:

c.ModelForm(
    model=TodoForm,
    submit_url="/api/add",
    display_mode="inline",
)

Forms, tables, navigation, and events are all declared server-side in Python. The catch-all route serves the FastUI React shell:

@app.get("/{path:path}")
def spa_root() -> HTMLResponse:
    return HTMLResponse(prebuilt_html(title="FastUI Todo"))
