remote-local 0.0.2

Expose your local FastAPI, NiceGUI, or development servers remotely — easily, reliably, and for free.

remote-local

Expose your local FastAPI, NiceGUI, or development servers remotely — easily, reliably, and for free.

remote-local is a simple and robust middleware that automatically creates a public tunnel for your local server using ngrok (and more in the future).
It handles session cleanup, hot reloads, and retries automatically — no manual setup required.

---

Features

• 🌍 Expose your local server remotely with one line of code.
• ⚡ Fully compatible with FastAPI, NiceGUI, or any ASGI app.
• 🔄 Handles hot reloads and session recovery automatically.
• 🔒 No external configuration required — works with free ngrok accounts.
• 🛠️ Designed for development, testing, and remote integrations.

---

Installation

pip install remote-local

---

Quick Usage

from nicegui import app, ui
from remote_local import NgrokMiddleware

NgrokMiddleware(app, port=8080)

@ui.page('/')
async def main_page():
    ui.label('Hello World')

ui.run(port=8080, reload=True)

✅ That's it! Your local server is now publicly accessible through a secure URL.

By default, a /server-info endpoint is also created, showing the current public URL and server status.

---

Environment Variable: PUBLIC_URL

If your server is already running with a public URL (for example, in a production deployment), you can set the PUBLIC_URL environment variable. When PUBLIC_URL is set, the middleware will skip starting ngrok and use the provided URL as the public-facing address for your app.

• If PUBLIC_URL is set, ngrok will not be started and the middleware will simply use this value.
• If PUBLIC_URL is not set, the middleware will start ngrok and set the public URL automatically.

Example:

export PUBLIC_URL=https://your-production-url.example.com

---

Configuration Options

You can customize the middleware:

NgrokMiddleware(
    app,
    port=8080,
    max_wait_seconds=60,    # how long to retry if ngrok fails initially
    fallback_to_localhost=False,  # fallback to localhost if ngrok fails
    expose_server_info=True,      # create a /server-info endpoint
)

Future Plans

• Support for other tunnels (Cloudflared, Localhost.run, etc.)
• More flexible server info APIs
• Auto-detection of multiple servers
