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:
sh
touch index.js
- Add this JavaScript code into it:
```js // 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:
sh
node index.js

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}) }```
