Breaking

• This package is now pure ESM. Please read this.
  • If you use TypeScript, you need to use TypeScript 4.7 or later. Why.
  • If you use a bundler, make sure it supports ESM and that you have correctly configured it for ESM.
  • The Chalk issue tracker is not a support channel for your favorite build/bundler tool.
  • It's totally fine to stay on Chalk v4. It's been stable for years.
• Require Node.js 12.20 fa16f4e
• Move some properties off the default export to individual named exports:
  • chalk.Instance → Chalk
  • chalk.supportsColor → supportsColor
  • chalk.stderr → chalkStderr
  • chalk.stderr.supportsColor → supportsColorStderr
• Remove .keyword(), .hsl(), .hsv(), .hwb(), and .ansi() coloring methods (#433) 4cf2e40
  • These were not commonly used and added a lot of bloat to Chalk. You can achieve the same by using the color-convert package.
  • How to migrate from .keyword()
• The tagged template literal support moved into a separate package: chalk-template (#524) c987c61

-import chalk from 'chalk';
+import chalkTemplate from 'chalk-template';
-chalk`2 + 3 = {bold ${2 + 3}}`;
+chalkTemplate`2 + 3 = {bold ${2 + 3}}`;

Improvements

• Bundle dependencies 04fdbd6
  • This means Chalk no longer has any dependencies 🎉
• The install size is less than half of v4.
• Add overline style (#433) 4cf2e40
• Preserve function prototype methods (#434) 0fba91b
