How do I use webpack dynamic imports inside an NPM package?

I have a navbar npm package that I import into other projects. It dynamically imports FontAwesome icons based on a JSON config file loaded from a web server at runtime.

When I build the navbar package, the entire FontAwesome library ends up as chunks in the build directory, as I would expect.

When I import that navbar module in another project, that project's build does not include the FontAwesome chunks. So the dynamic import HTTP calls get a 404.

I can't find much about this use case online, possibly because I don't know the terms to look for, possibly because this is a terrible idea in the first place.

How can I get webpack to see that a package has dynamic imports and to copy over the necessary chunks to the build directory?

Solution

  • You can try running npm publish --dry-run to see what gets published and if its missing anything compared to your build folder.

    You can also try running npm publish <path to build folder>.
