Once installed, the simple way to run Node-RED is to use the `node-red` command in a command prompt: If you have installed Node-RED as a global npm package, you can use the node-red command:
C:>node-red
This will output the Node-RED log to the terminal. You must keep the terminal open in order to keep Node-RED running.
Open browser and run http://127.0.0.1:1880
You will see this window.
Note that running Node-RED will create a new folder in your %USERPROFILE% folder called .node-red. This is your userDir folder, think of it as the home folder for Node-RED configuration for the current user. You will often see this referred to as ~/.node-red in documentation. ~ is shorthand for the user home folder on Unix-like systems. You can use the same reference if using PowerShell as your command line as recommended. If you are using the older cmd shell, that won’t work.
Setup Node-Forge
Close the browser or cancel Node server if it is running.
cd %USERPROFILE%\.node-red
npm install node-red-node-forge --save
