NodeJS: How To Colorize Text

2019-08-28

Intro

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
  • 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 = chalk.bgGreen.black.underline;
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")}.`);

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

Run it from the terminal

  • Run it:
node index.js
  • Result:
