v3.0.0...v4.0.0

v3.0.0

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
• Add ansi and bgAnsi to TypeScript declaration (#369) 18c280d

Color detection

• The FORCE_COLOR environment variable can now be used to force a certain color level (#315) af4a078
• Add support for GitHub Actions in the color detection chalk/supports-color@79d1303
• Give TERM=dumb higher priority in the color detection chalk/supports-color@8d6a7b5
• Add support for VT220 in the color detection chalk/supports-color@ed0fe39

Fixes

• Fix support for nested styles (#335) 87156ce
• Fix const enum for TypeScript (#364) 4e65299
• Fix TypeScript type for supportsColor which is top‑level only (#342) b3e9b91
• Fix TypeScript type for chalk.supportsColor (#347) d82b2a6
• Fix TypeScript type for tagged template literal argument to accept unknown instead of just string (#316) 7f6e563
