NodeJS: How To Colorize Text


So we installed NodeJS on our machine.

We also know How to Get External Packages.

Now we want to learn how to colorize text using chalk.

Write a simple script

  • Open your terminal
  • Create a file named index.js:
touch index.js
Enter fullscreen mode Exit fullscreen mode
  • Add this JavaScript code into it:
// import chalk
const chalk = require('chalk');

// Example 1: inline styling, blue background and underline
console.log(chalk.bgBlue.underline('Example 1'));

// Example 2: create reusable style  
const success =;
console.log(success('Example 2'));

// Example 3: you can do a lot of stuff, e.g. using hex values and template literals
const customize = chalk.hex('#B4DA55').bold;
console.log(`This is ${customize('Example 3')}.`);
Enter fullscreen mode Exit fullscreen mode

Note: Chalk has a lot of available styles, read the docs of chalk.

Run it from the terminal

  • Run it:
node index.js
Enter fullscreen mode Exit fullscreen mode
  • Result:

Alt Text

I recently used the same thing to have color-coded logging on my node app :)

looks a little something like this:

function debug(message) {
    const timestamp = new Date().toString()
    console.log('\x1b[36m%s\x1b[0m', `${timestamp} - ${message}`)

function error(message) {
    const timestamp = new Date().toString()
    console.error('\x1b[31m%s\x1b[0m', `${timestamp} - ${message}`)
