Default Bundler Loaders
Several loaders are available for the liferay-npm-bundler by default:
babel-loader: processes source files with Babel. This avoids an extra build step before the bundler.
copy-loader: copies source files (static assets) to the output folder.
sasson source files, so you can generate static CSS files. It can be chained before
See the liferay-js-toolkit loaders showcase for an example use case of the liferay-npm-bundler’s loaders. If the default loaders don’t meet your requirements, you can follow the instructions in Creating Custom Loaders for the Bundler to create your own loaders.
