How to install nodejs and node red together using a batch file in Windows

To install Node.js and Node-RED together using a batch file in Windows, you can follow these steps:

1. Download Node.js installer:

   • Go to the Node.js website (https://nodejs.org/en/download/).
   • Download the Windows installer for the desired Node.js version (e.g., the LTS version).

2. Create a batch file:

   • Open a text editor (e.g., Notepad) and create a new file.
   • Copy and paste the following commands into the file:

   batchCopy code
   @echo off
   
   
   
   REM Install Node.js
   
   echo Installing Node.js...
   
   msiexec /i <path-to-nodejs-installer.msi> /qn
   
   
   
   REM Install Node-RED
   
   echo Installing Node-RED...
   
   npm install -g --unsafe-perm node-red
   
   
   
   REM Start Node-RED
   
   echo Starting Node-RED...
   
   node-red
   
   

   • Replace <path-to-nodejs-installer.msi> with the actual path to the Node.js installer you downloaded in step 1.

3. Save the file with a .bat extension (e.g., install_node_red.bat).

4. Run the batch file:

   • Double-click on the batch file (install_node_red.bat) to run it.
   • The script will first install Node.js using the provided installer, then install Node-RED using npm, and finally start Node-RED.

Note: Make sure you have administrative privileges on your Windows machine to install software and modify system paths.

After running the batch file, you should have Node.js and Node-RED installed on your system, and Node-RED should be running. You can access the Node-RED web interface by opening a browser and navigating to http://localhost:1880.
