How to browserify NPM package for use in browser

I want to make an NPM package useable in the browser in a manner that makes all its exports available, without having to rerun the bundling process every time my application code uses an additional export.

How do I do this? All the tools I’ve found seem to want to create a bundle based on what dependencies my application code uses, which requires setting up a watch process and rebuilding the bundle every time I edit my code.
