Simple Example for websockets

This example demonstrates how to use websockets. To learn more about websockets see the MDN.

Encryption

Please note the following from the MDN about websockets:

The URL to which to connect; this should be the URL to which the WebSocket server will respond. This should use the URL scheme wss://, although some software may allow you to use the insecure ws:// for local connections.

Server

The default configuration of the server runs locally (localhost) on port 8001.
To create a new websocket server with python or nodejs:

• python: python3 server.py
• nodejs: npm install && node server.js

Client

You can connect to the server via the js browser client. Just open the website client.html on your local computer. To test it in a simple project setting you can also launch a local webserver via python, node or php etc.

• local file: open it locally in your browser
• php: php -S localhost:8000 and go to http://localhost:8000/client.html
• python: python3 -m http.server 8000 and go to http://localhost:8000/client.html
• nodejs: use npm package http-server: npm install -g http-server and http-server
