How to exclude folders/files with .npmignore?

Question

I generated a lib folder with Rollup for my npm package.

This is my lib folder structure:

/lib
  /components
  /stories

In my package.json, I white listed the /lib folder in the files key like so:

// package.json

{
  "files": [
    "/lib"
  ]
}

What I wish to achieve is to exclude the /stories when I npm publish

So I added a .npmignore file with the following content:

// .npmignore

/lib/stories

But this isn't working, the /stories folder are still included when I publish.

You need a trailing slash to mark your stories as directory. Otherwise .npmignore thinks it's a file:
/lib/stories/
