# Deploy and Host FastAPI + VanillaJS on Railway

FastAPI + VanillaJS is a zero-bloat, lightning-fast fullstack template. It combines a high-performance Python backend with a clean, dependency-free JavaScript frontend, all managed seamlessly by the modern `uv` package manager. It’s designed for developers who want to ship rapidly without Node bundlers or heavy frameworks.

## About Hosting FastAPI + VanillaJS

Hosting FastAPI + VanillaJS on Railway is a frictionless experience thanks to its unified, containerized monorepo architecture. The template includes a pre-configured Dockerfile that copies the `uv` binary, installs Python dependencies, and serves both the API and static frontend from a single process. Deployment is as simple as connecting your GitHub repository. Railway automatically detects the Dockerfile, injects the required `$PORT` environment variable, and utilizes the included `railway.toml` to monitor the `/health` endpoint, ensuring your app routes traffic correctly and remains highly available.

## Common Use Cases

- Rapid prototyping of full-stack web applications
- Building lightweight, high-performance REST APIs with an integrated web UI
- Serving single-page applications (SPAs) without a Node.js build pipeline

## Dependencies for FastAPI + VanillaJS Hosting

- Python 3.12 (via official slim Docker image)
- `uv` (Astral's high-speed Python package and project manager)
- Docker (Used by Railway to build and run the unified environment)

### Deployment Dependencies

- [FastAPI Documentation](https://fastapi.tiangolo.com/)
- [uv Python Package Manager](https://github.com/astral-sh/uv)
- [Railway Dockerfile Documentation](https://docs.railway.app/reference/dockerfiles)

### Implementation Details

To ensure maximum stability in a containerized environment, this template bypasses `uv run` at runtime. Instead, the Dockerfile directly executes the compiled binaries from the generated virtual environment. It also dynamically binds to Railway's assigned port:

```dockerfile
CMD sh -c ".venv/bin/uvicorn app.main:app --host 0.0.0.0 --port ${PORT}"
```

## Why Deploy FastAPI + VanillaJS on Railway?
