babel-preset-steelbrain

5.0.3 verified Sat Apr 25 auth: no javascript

Personal Babel preset for latest ES features (stage-0) with React and decorator support. Version 5.0.3 is the latest stable release. This preset blacklists the `regenerator` transform by default to avoid including regenerator runtime, assuming Node.js built-in generator support. It offers configuration options similar to `babel-preset-env`, including `exclude` and `modules` options. Alternatives include `@babel/preset-env` and `@babel/preset-react`. Release cadence is irregular as it's a personal preset.
