​

What It Does

• chalk.color('text') → styleText('color', 'text')
• chalk.color.modifier('text') → styleText(['color', 'modifier'], 'text')
• Removes chalk from package.json dependencies
• Updates both CommonJS and ES module imports

​

Usage

npx codemod nodejs/chalk-to-util-styletext

​

Examples

​

Basic Color Transformations

import chalk from 'chalk';
console.log(chalk.red('Error message'));
console.log(chalk.green('Success message'));
console.log(chalk.blue('Info message'));

import { styleText } from 'node:util';
console.log(styleText('red', 'Error message'));
console.log(styleText('green', 'Success message'));
console.log(styleText('blue', 'Info message'));

const chalk = require('chalk');
console.log(chalk.red('Error message'));
console.log(chalk.green('Success message'));
console.log(chalk.blue('Info message'));

const { styleText } = require('node:util');
console.log(styleText('red', 'Error message'));
console.log(styleText('green', 'Success message'));
console.log(styleText('blue', 'Info message'));

​

Chained Modifiers

import chalk from 'chalk';
console.log(chalk.red.bold('Important error'));
console.log(chalk.green.underline('Success with emphasis'));

import { styleText } from 'node:util';
console.log(styleText(['red', 'bold'], 'Important error'));
console.log(styleText(['green', 'underline'], 'Success with emphasis'));

​

Stored Style Functions

const chalk = require('chalk');
const red = chalk.red;
const boldBlue = chalk.blue.bold;

console.log(red('Error'));
console.log(boldBlue('Info'));

const { styleText } = require('node:util');
const red = (text) => styleText('red', text);
const boldBlue = (text) => styleText(['blue', 'bold'], text);

console.log(red('Error'));
console.log(boldBlue('Info'));

​

Compatibility

​

Supported Methods

• Colors: black, red, green, yellow, blue, magenta, cyan, white, gray, grey
• Background colors: bgBlack, bgRed, bgGreen, bgYellow, bgBlue, bgMagenta, bgCyan, bgWhite
• Text modifiers: bold, dim, italic, underline, strikethrough

​

Unsupported Methods

​

Automatic Cleanup

​

Limitations

• Complex conditional expressions in some contexts may need manual review
• Template literals with chalk are not automatically converted
• Custom chalk themes require manual migration

​

Benefits of Migration

• Remove external dependency: One less package to maintain and update
• Native performance: Built-in APIs are optimized for Node.js
• Standard API: Aligned with Node.js core module conventions
• Smaller bundle: No need to include chalk in your dependencies
