We add the main project’s node_modules to NODE_PATH when running Babel and similar tools. There are some known issues 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.:
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.
Save as many bytes as possible when printing
Write comments to generated output (true by default)
Do not include superfluous whitespace characters and line terminators. Defaults to auto if not set.
Output inline or external sourcemap from the babel compile. External sourcemaps will be written to the target with the output filename + “.map”. Input sourcemaps can be read from js.Build and node modules and combined into the output sourcemaps.
