css files have incorrect hashes

[benmccann]

The CSS files are getting the hash for the JS files.

E.g. npm run build on hn.svelte.dev returns:

__sapper__/build/client/[id].1ed50b8f.js
__sapper__/build/client/[id].1ed50b8f.css

The name for CSS is chosen by replacing the .js of the JavaScript file path with .css:

sapper/src/core/create_compilers/extract_css.ts

Line 148 in a5d8caf

const output_file_name = chunk.file.replace(/\.js$/, '.css');

To fix this (assuming it's actually a bug) we need to stop blindly replacing .js with .css in the extract_css codepath

@benmccann why is this an error?

If you change only the css and not the js I believe the file hash will not change as it should
