You can use the command line to do anything you can do in a GUI, if the know the right command.
In this post, we'll learn how you can run Node scripts from the command line.
To begin, let's start off with our example script:
const string = "123"; console.log(string);
Of course, if we ran this in the browser, we would get:
However, since we want to run it in Node, let's save this as a file called
Once we did that, open your command line and make sure you're in the same folder as the script.
Assuming you have Node installed, this is how you can run your script:
You simply need to use the
node command and pass it the path to the file you want to run.
Now, if you want to keep running this file every time it changes, you can use a module called
nodemon for this exact scenario.
Install it locally:
npm install -g nodemon
Once you've done that, you can instead call
nodemon instead of
In this post, we learned how to run Node scripts from the command line.
Simply use the
node command to run a script or
nodemon to watch for changes and re-run it.
