There will be some nice headlines in the next Hugo version, among them Hugo Modules.
I spent some time porting a theme of mine to the new setup. It had some elaborate home built bundler setup that ported a Ruby based site to Hugo … And I must say that it was really nice seeing how easy it was to map a “totally not Hugo” site into by mounting folders doing some SCSS and JS overrides etc.:
You will like the new mount configuration, which can be used for any of Hugo’s component types (content, assets, static …) and also to define a project/theme’s own mounts. Really nice.
