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.
While this is a beta release, the code is well-tested and fairly stable.
We encourage you to test it out and report any issues.
$ npm install chalk@3.0.0-beta.1
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 this.
- Migrate:
-if (chalk.enabled) {}
+if (chalk.level > 0) {}
-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).
- Rename the
ChalkOptions
TypeScript type toOptions
