Specifying include/exclude breaks packaging

Background: I am experimenting with methods to potentially fix some nonsense perpetrated by Webpack in components I am incorporating into my application. Specifically, I am working with Vue.js and am using rollup, rollup-plugin-vue, and rollup-plugin-babel (as well as several others, as my example repo demonstrates).

When I specify the babel configuration as:

babel({ exclude: ['node_modules/**'] })

Everything works. If, however, I specify an include that contradicts the exclude:

babel({ exclude: ['node_modules/**'], include: ['node_modules/vue-password/**'] })

things break. I have created a repository (rollup-babel-plugin-include-exclude-issue) that demonstrates this. It’s not exactly minimal, but I have been able to determine that it is the babel plugin that is causing the problem through some careful checking of configuration options.

I have received various errors including:

[!] (plugin Rollup Core) Error: Could not load fs (imported by …/rollup-babel-plugin-include-exclude-issue/node_modules/graphql.macro/es/utils/expandImports.js): ENOENT: no such file or directory, open 'fs'

and other related errors (specifically related to graphql.macro) that appear to be somewhat random.

It seems to me that this should work (exclude all items from node_modules except the items that I have whitelisted because I’m doing something potentially stupid), or at least continue the compile…but I’m not sure what’s going on here.

This really depends on which of those options (include/exclude) are considered as the one with more priority. You could always make a compelling argument (with usage examples) for current semantics, and you can do the same for your proposed one.

This plugin actually uses "standard" rollup-pluginutils and its createFilter helper to handle those 2, so I don't plan to change how this behaves as it's handled externally and should be handled in the same way across all rollup plugins which use include/exclude options.

The good thing is that you actually can use a regexp instead of a glob so maybe it would be easier for you to create a single include (or exclude) rule with RegExp because when you mix both of those options then things become hard to reason about and confusing.

I just opened rollup/rollup-pluginutils#67 to suggest a documentation update. I will suggest the same documentation update for rollup-plugin-babel from a comment on rollup/rollup-pluginutils#4. I believe that this will satisfy my issue, although I could wish for better handling.

The reported issue in rollup-pluginutils has been closed because this was actually documented there. Seems like this issue can be closed too. If you have any further issues - please create a new one.
