Migrates usage of the chalk npm package to the Node.js built-in util.styleText() API. Replaces the chalk import with { styleText } from node:util and rewrites all chalk method calls accordingly. Chained chalk styles are converted to an array of style strings.

Run this codemod with:

npx codemod @nodejs/chalk-to-util-styletext

Basic color methods (ESM default import)

-import chalk from "chalk";
+import { styleText } from "node:util";

-console.log(chalk.red("Error message"));
-console.log(chalk.green("Success message"));
-console.log(chalk.blue("Info message"));
+console.log(styleText("red", "Error message"));
+console.log(styleText("green", "Success message"));
+console.log(styleText("blue", "Info message"));

Chained styles

-import chalk from "chalk";
+import { styleText } from "node:util";

-console.log(chalk.red.bold("Error: Operation failed"));
-console.log(chalk.green.underline("Success: All tests passed"));
-console.log(chalk.yellow.bgBlack("Warning: Deprecated API usage"));
+console.log(styleText(["red", "bold"], "Error: Operation failed"));
+console.log(styleText(["green", "underline"], "Success: All tests passed"));
+console.log(styleText(["yellow", "bgBlack"], "Warning: Deprecated API usage"));

CommonJS require

-const chalk = require("chalk");
+const { styleText } = require("node:util");

-const error = chalk.red("Error");
-const warning = chalk.yellow("Warning");
-const info = chalk.blue("Info");
+const error = styleText("red", "Error");
+const warning = styleText("yellow", "Warning");
+const info = styleText("blue", "Info");

 console.log(error, warning, info);

Chalk methods that have no direct util.styleText equivalent — including hex(), rgb(), ansi256(), bgAnsi256(), visible(), and new chalk.Chalk() — are skipped. A warning is printed for each unsupported call, and those call sites are left unchanged for manual review.
