Download the repository into a folder and install the dependencies. You may do this by running:
# Download the repository via git git clone https://gitlab.com/webthings/webthing-day-of-week.git # Install project dependencies npm ci
# Specify a port in Bash (Linux and Mac) #export PORT=8000 # Specify a port in Batch (Windows) #SET /A PORT=8000 npm start
This starts a web server on your machine. By default it starts on TCP port 8000. Determine your system’s local IP address and add the Web Thing to your gateway.
It fails to start with
Error: listen EADDRINUSE :::8000
You already have an instance of this project or another application running on the mentioned TCP port. On a computer a port cannot be assigned to two servers.
On Linux you can identify open TCP ports and the owner process with the command
The server is not reachable from another computer
Ensure that the computers are on the same network. Test their connectivity with the
ping command. If they are connected, the computer running the server might block the TCP port with its firewall.
