Most of the time, files installed at /usr/lib/nodejs needs browserification (webpacking/module bundling) to be able to be installed at /usr/share/javascript. Though there are now formats like UMD (Universal Module) which allows the code to be run in both environments. I think in most cases where the software supports both environments, umd modules are used, so it would be fine to provide a single binary package. I just explained why these two separate targets exist. >> 2.

I see two problems with that approach. 1. It makes these modules installable but unuseable in architectures where nodejs itself is not available. 2. We won't be able to specify a minimum version of nodejs for these modules. For example, node-regexpu-core required nodejs >= 6 and this prevented its testing migration for a long time because testing only had nodejs 4 for a long time. I think separate binary should be allowed at least in the second case. >> If you take example of node-handlebars source package, libjs-handlebars >> is targeted at browsers and does not need to declare a dependency on >> nodejs.

It has binding for different languages (like ruby-handlebars-assets) and also a command line interface. The command line can be used for compiling handlebars templates.
