cd LaserWeb3
npm install

Manually start the server

cd /home/pi/LaserWeb3
node server.js   

Start the frontend

• Open Chrome (or Chromium) on any PC in your network.
• Open URL RasPi-IP:8000 (replace RasPi-IP with the IP of your RasPi)
• Click on Comms tab
• Click on "Server Connection"
• Change Server-IP to RasPi-IP:8000 (replace RasPi-IP with the IP of your RasPi)
• Click connect

You should see a green message "Server connected" in the log area (bottom right)

Setup Systemd to automatically start the server

First, open laserweb3.service in a text editor and correct the path for node according to your system (probably /usr/bin/node instead of /usr/local/bin/node).

Then, execute the following console commands:

cp /home/pi/LaserWeb3/laserweb3.service /etc/systemd/system/laserweb3.service
sudo systemctl enable laserweb3.service
sudo systemctl start laserweb3

You can check the status of LaserWeb with

sudo systemctl status laserweb3

You can restart LaserWeb with

sudo systemctl restart laserweb3

The logs will get added to /var/log/syslog
