Install dependencies:
npm ci
Run the Tailwind build (using postcss-loader in Webpack):
npm run build
Observe that:
- Tailwind prints an error to the console but does not throw, consequently not aborting Webpack.
- Webpack successfully runs and writes meaningless output to
bin/output.css. - This output doesn't contain any of the valid CSS in
input.css.
This is especially bad when a bundler like Webpack is configured to use a persistent cache; Tailwind only prints these errors to the console the first time and then never again until the cache happens to be invalidated.
