There are three primary elements of process.argv array: You just pass arguments to a Node.js application and these arguments are handled by process.argv by default.

HSMWORKS KEY COMMANDLINE INSTALL

Using process.argv is the simplest way of parsing arguments in Node.js and you do not need to install any additional package or library for that. Here we will first see to parse arguments using process.argv and later with yargs and minimist.

How to Parse Command Line Arguments in Node.js Here is an example syntax, how the command line arguments look like: ДЄrguments are separated by space and runtime could be anything like sh, java, node, etc. WhatвЂ™s the example syntax of Command-Line Arguments? It allows you to pass information to an application before it starts and also you can pass an unlimited number of arguments through Command-Line. Why Use Command Line Arguments?Д¬ommand-line arguments are very flexible as they are passed as strings to your program and string data types can easily be converted to other types. In Node.js, all the command-line arguments given to the shell are forwarded to the process in an array called вЂargument values(argv).вЂ™ Later Node.js uses this array for every running process in the form of process.argv or you can say arguments are by default stored in the process.argv. These arguments usually include information used to set property or configuration values for an application. What are Command Line Arguments?ДЄ command-line argument is a string of additional information or commands that are passed into a program while running it through the Command Line Interface(CLI) of an OS. In this article, we will see how you can parse command line arguments in Node.js using process.argv, yargs, and minimist. By default, Node.js is able to handle your arguments but if you want some extra features then you can use third-party tools and packages like yargs and minimist. Node.js applications also accept command-line arguments like any other programming language. Node.js applications are written in JavaScript. We use it to develop applications that use JavaScript both on the server and client sides. Node.js is an event-based, open-source, and asynchronous I/O framework that uses GoogleвЂ™s V8 JavaScript engine.
