make a log viewer

Hi, i’ve made a web app for a customer that can write some system preferences (on a raspberry pi) and reboot the system.
Now he has requested me to show, in the web interface, the log file of a console app made in xojo too.
The log is a simple file text with rows added by the console app, any suggestion how to make a viewer with auto refresh in a web app?


Add a web timer and periodically reread the text file.
