Service worker warns: No directory provided. Skipping CSS generation

[mattpilott]

Been seeing this warning lately, not sure what has led to it

Presumably it's something that can be resolved in the rollup config

Relevant changes that I found:

The message started to appear since sapper@0.29.0.

Any idea how to fix it?

I hid the warning message by adding this line into the onwarn function of rollup.config.js

  (warning.plugin === 'css' && warning.message === 'No directory provided. Skipping CSS generation') ||

Full onwarn function:

const onwarn = (warning, onwarn) =>
  (warning.code === 'MISSING_EXPORT' && /'preload'/.test(warning.message)) ||
  (warning.code === 'CIRCULAR_DEPENDENCY' && /[/\\]@sapper[/\\]/.test(warning.message)) ||
  (warning.code === 'THIS_IS_UNDEFINED') ||
  (warning.plugin === 'css' && warning.message === 'No directory provided. Skipping CSS generation') ||
  onwarn(warning)

We should identify and remove the problem. This is not a good idea. I think :)

I would like also to get on that solution on that problem.

Hi, I just updated Sapper to 0.29.1 and I get this message
No directory provided. Skipping CSS generation, as in the screenshots above.

What's the issue and.. how could I fix that ?

[Disclaimer: I did not test to see if the latest version of the Sapper template still results in this warning]

If you aren't using the latest version of this Sapper template, then your config hasn't been updated to avoid the warning. So, start over using the latest version of the template or compare its config files and dependencies to yours to see if you can solve the error without starting over.

The message No directory provided. Skipping CSS generation showed up after I updated the packages to the latest version available.
I did solve going "back" to the Sapper template packages version.

A fix has been merged to the master branch, but hasn’t been released yet. To get Sapper with the latest commits (even if not part of a tagged version) you can install it directly from the master branch on GitHub:
npm install -D sveltejs/sapper#master
