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

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

Or if you have esModuleInterop enabled:

-import chalk from 'chalk';
+import * as chalk from '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.
