Babel Config

Factory functions for creating preset Babel configurations. Primarily used in unison with the Lumos CLI.

Extending config

Update package.json:

{
  "lumos": {
    "eslint": {
      "plugins": ["styled-components"]
    }
  }
}

Create file in configs folder:

configs/babel.js

modules.exports = {
  plugins: ['styled-components'],
};
