In this article, you will see how to pass command-line arguments to your Node.js application. You will also learn how to access them.
However, before proceeding further, let’s start with some basic stuff. To run a Node.js application, you run the following command in your terminal:
node index.js
Thus, when you run the above command, you can pass any number of arguments. When it comes to command-line arguments, there are two types:
node index.js myArg
node index.js myArg=myVal
Now, the next step is to learn how you can access these arguments in your Node.js application.
In Node.js, the process
object is a global object and contains information about the current Node processes. Since it’s a global object, you have access to it directly even though you do not import it into your application.
