We add the main project's `node_modules` to `NODE_PATH` when running Babel and similar tools. There are some known [issues](https://github.com/babel/babel/issues/5618) with Babel in this area, so if you have a `babel.config.js` living in a Hugo Module (and not in the project itself), we recommend using `require` to load the presets/plugins, e.g.:
```js
module.exports = {
presets: [
[
require("@babel/preset-env"),
{
useBuiltIns: "entry",
corejs: 3,
},
],
],
};
```
## Options
config
: (`string`) Path to the Babel configuration file. Hugo will, by default, look for a `babel.config.js` in your project. More information on these configuration files can be found here: [babel configuration](https://babeljs.io/docs/en/configuration).
minified
: (`bool`) Save as many bytes as possible when printing
noComments
: (`bool`) Write comments to generated output (true by default)
compact
: (`bool`) Do not include superfluous whitespace characters and line terminators. Defaults to `auto` if not set.
verbose
: (`bool`) Log everything
sourceMap
: (`string`) Output `inline` or `external` sourcemap from the babel compile. External sourcemaps will be written to the target with the output file name + ".map". Input sourcemaps can be read from js.Build and node modules and combined into the output sourcemaps.
