Avoiding packing your micro apps into NPM packages

Another common trend within the SPA world is to convert any sharable modules into NPM packages for easier distribution and then import them into other apps.

In our experience, we have seen a few teams package and version their micro apps into NPM modules before importing them into the host or assembly app. We strongly discourage this practice for the primary reason that every time a new version of a micro app is published as an npm module, all the hosts using that micro app will need to update their package.json files and rebuild and redeploy their apps, defeating the primary principle of independent deployments. We covered this in a bit of detail in Chapter 2, Key Principles and Components of Microfrontends, in the Prefer runtime integrations section.
