TL;DR
Create a fun Node.js CLI app by setting up a project folder, adding an index.js with a Node shebang, and using libraries like figlet, chalk, and chalk-animation to style and animate console output. Test it locally with node index.js, then update package.json, publish to npm, and run it globally via the command name you defined.
Introduction
Would you like to create a CLI (Command Line Interface) application with your friends? Follow these steps to get started:
Create a new directory for your CLI app
Install the necessary packages for beautiful text and colors
Create a new file named
index.jstouch index.jsAdd the following line at the top of the
index.jsfile
The line#!/usr/bin/env nodeat the beginning of a JavaScript file is called a shebang line. It instructs the system to
use the Node.js interpreter to run the script.
Create an Immediately Invoked Function Expression (IIFE) to begin the script. Let's start by using Figlet
Now, let's utilize chalk with simple
console.log()statements and template literals to customize the console logs
Now, let's add some animation using chalk-animation for the closing words
Run
node index.jsto see the changes in the UI.Finally, to publish your package to npm, make changes in
package.json
Once your package is published, you can run the command using the name specified in
package.json. For instance, in my case, it'sakshaygore, so I would run:
