Not able to init websocket connection: ws does not work in the browser

This issue has been tracked since 2021-12-24.

Description
I am trying to setup a web interface using svelte and this package with a turtlebot3 simulation on ros2 galactic.
I have used npm install roslib to set up this npm module in my project.

This is what I have in my client-side script (JS):

ros = new ROSLIB.Ros({
  url: 'ws://localhost:9090'
})

I have the simulation up and running with rosbridge_suite and rosbridge_server is up on port 9090 of localhost.

  • Library Version: "roslib": "^1.1.0"
  • ROS Version: galactic
  • Platform / OS: wsl2 (ubuntu 20.04)

Expected Behavior
I should be able to set up a WebSocket connection.

Actual Behavior
When I open up my web interface I get this error:

Uncaught (in promise) Error: ws does not work in the browser. Browser clients must use the native WebSocket object

rosbridge_suite has a ROS2 version. ros2-web-bridge is not actively maintained...
