Babel

🐠 Babel is a compiler created by Sebastian McKenzie in 2014 to convert ES6 to ES5 (originally called 6to5). It has since become a toolchain that enables developers to write any next generation JavaScript and serves as a testing ground for proposals from TC39, the technical committee that specifies ECMAScript. Babel can also convert JSX syntax and strip out type annotations from both Flow and TypeScript. Babel is built out of plugins. Compose your own transformation pipeline using plugins written by the community or write your own.

Describe the feature

Related with swc-project/swc#3859.

We want to establish initial feature parity to existing @swc/cli to plan out migration with possible breaking changes.

These are initial flags we'd like to have.

Expected Behavior

defaultMode is used in Grommet component along with themeMode prop to determine initial theme mode between dark and light themes. As this property is used by Grommet Theme Designer, Grommet HPE Theme and in HPE Design System I would expect it to

For the most part this just works, but functions within tagged markup get weird indent assertions, e.g.,

        ${collection.map((item) => {
          const { prop1, prop2 } = workWith(item);  // eslint: expected indentation of 4 but found 10 (indent)
          return html`  // eslint: expected indentation of 4 but found 10 (indent)
            <${Widget} prop1=${prop1} prop2=${prop2} />

Validate the entire tree of options passed to preset.

Maybe, each plugin can export a list of options that only babili preset understands and we can validate them only when using the preset and not when using the plugin separately.

module.exports = function plugin() {};
module.exports.options = PropTypes.object({
  n: PropTypes.number
});

Or, this can be implemented in bab
