This flow uses http nodes and web sockets nodes to serve up a simple web page with a chat application that colours messages depending on whether they are positive or negative according to the sentiment node.

Copy the flow, and import it from the clipboard using Node-RED on FRED.

Change the URL ws://fred.sensetecnic.com/public/guides/receive and ws://fred.sensetecnic.com/public/guides/publish, replacing guides with your FRED user name.

Change the same URL to get it working on a 'stock' Node-RED install, or check it out on the Node-RED flows library - flows.nodered.org.

# only start this service after the httpd user process has started
#start on syno.network.ready
start on runlevel 2

# stop the service gracefully if the runlevel changes to 'reboot'
stop on runlevel [06]

# run the scripts as the 'admin' user. Running as root (the default) is a bad idea.
