Host HTML pages - Domino

This example integrates a simple Python HTTP server with Domino to serve static HTML. You can extend it with JavaScript or additional pages in your project.

Files

You’ll need to create a file in your project (in addition to your files required for your page such as index.html). app.py

import http.server
import socketserver
PORT = 8888
Handler = http.server.SimpleHTTPRequestHandler
httpd = socketserver.TCPServer(("", PORT), Handler)
print ("serving at port", PORT)
httpd.serve_forever()

When publishing the App, select app.py as the App file. When Domino launches your App, it runs app.py in the container that contains your project files. Apps published in Domino must serve traffic on port 8888.
