Simple Dart + WebSocket demo

The post introduces a small Dart WebSocket demo that connects to a server, sends messages, and illustrates several Dart language features. It points to the open source project and notes that the code is meant to show how Dart can be structured without wrapping everything in classes.

Reading notes

#

• The demo connects to a WebSocket server and sends messages.
• The code is available as an open source project on GitHub.
• Dart allows top-level functions and top-level variables.
• The example uses libraries for modularity, including dart:html.
• Tree-shaking removes unused code during compilation.
• Inline function syntax is used for callback logic.
