node: Execute the specified file restarting the process when an imported file is changed (requires Node.js version 18.11+).
$ node --watch ${filename}
try on your machine
The command "node --watch ${filename}" is used to run a Node.js script and watch the specified file for changes. Here is a breakdown of the command:
- "node" is the executable command used to run Node.js scripts.
- "--watch" is a command-line flag or option that tells the Node.js runtime to monitor a specified file for changes.
- "${filename}" is a placeholder for the actual file name or file path. You need to replace it with the name of the file you want to watch for changes.
When you run this command in the terminal or command prompt, Node.js will start executing the specified file and continuously monitor it for any changes. If any changes occur, the script will automatically restart or update, allowing you to see the updated output or behavior based on the modifications made to the file.
This command is useful during development or when working on a script that relies on external file changes. It saves you from manually stopping and restarting the script every time you make changes to the file.

never run a command you are not sure if it is safe.
