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.
• 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

-if (chalk.level > Level.None) {}
+if (chalk.level > 0) {}

Improvements

• Use Object.setPrototypeOf as __proto__ could potentially be disabled (#​387) 63469d3

v3.0.0

Compare Source

This release has been in development for more than a year and massively improves performance and the time it takes to import Chalk.

Thanks to @​stroncium for his hard work on this. 🙌

Breaking

• Require Node.js 8 3ef170b
• Remove the .enabled property in favor of .level (#​356) 1f77953
  • Why: It was confusing to users to have two properties for detecting color support.
  • Migrate:

-if (chalk.enabled) {}
+if (chalk.level > 0) {}

• Remove chalk.constructor() in favor of chalk.Instance() (#​322) de2f4cd
  • Migrate:

-new chalk.constructor({level: 1});
+new chalk.Instance({level: 1})

Minor breaking

• Use CommonJS-compatible export in TypeScript definition (#​344) 98628d9
  • Why: Faking default export for TypeScript broke IntelliSense for JavaScript.
  • Migrate:

-import chalk from 'chalk';
+import chalk = require('chalk');

• Drop built-in Flow type definition d3be9c6
  • Why: None of us use Flow and we were not good at maintaining the type definition. You can get the types at flow-typed (needs to be updated to Chalk v3, open an issue on flow-typed).
• Rename the ChalkOptions TypeScript type to Options cf66156
• Remove dim style workaround for Windows (#​331) cd5de7a
  • Why: The issue was fixed in newer Windows 10 builds.
• Remove the blue color workaround for Windows (#​330) 2ca015c
  • Why: The issue was fixed in newer Windows 10 builds.

Enhancements

• Massively improve performance! (#​337) c08417e
• Improve require speed (#​358) 61aca7c
• Add chalk.stderr for printing to stderr (#​359) 2a53389
• Add blackBright color. It's the same as the gray color, but added for consistency. c25c32a
• Fix support for bracketed Unicode escapes in template literals (#​350) 9830948
• Export TypeScript types for colors and modifiers (#​357) 6b4d206
• Add ansi256 and bgAnsi256 to TypeScript declaration (#​368) fb8e85a
