Dart websocket in dart:io and dart:html

Question

I have seen two implementation of websocket in dart:io and dart:html. Which one should I use? Currently I prefer more the websocket in dart:io since it seems to fit more naturally how dart handle streams and asynchronous programming.

Answer 1

The dart:html library is used on the client-side and can be compiled to JavaScript.

Use dart:io for server-side code.

In a typical setup, you have a web server listening to WebSocket connections from the client, in which case you would use the one from dart:html. But of course you can also initiate WebSocket connections at the server if you ever need :)

Answer 2

• dart:io is only available on the server
• dart:html is only available in the browser
