sudo apt-get install ros-humble-rosbridge-server
# Clone this repository with submodules
git clone --recursive https://github.com/107-systems/l3xz_frontend
# Launch rosbridge socket server
ros2 launch rosbridge_server rosbridge_websocket_launch.xml &
# Start a http server in the webgui folder
cd webgui
python3 -m http.server 8080

Adding a new page

To add a new page, a HTML document needs to be created in the root (webgui) and linked in index.html. The setup functions, called after loading the static page, are expected to be implemented in javascript/setup in a new file. The callbacks for static webpage elements should be implemented in a new file in javascript/frontend.
