I'm recommending to use the custom extension to your styles which will be imported as a string. It will help to escape conflicts with .css
files for global styles or css-modules. The default asset type css
.
You can add the list of your custom extensions to .parcelrc
config. Syntax highlight custom extension
For example: styles.cssx
.
.parcelrc
{
"parcel-plugin-css-to-string": {
"assetType": ["cssx"]
}
}

You can configure minify CSS in production build, where custom configuration can be set by creating cssnano.config.js
file
cssnano.config.js
module.exports = {
preset: [
"default",
{
calc: false,
discardComments: {
removeAll: true
}
}
]
}
You can configure CSS transforming with PostCSS creating a configuration file using one of these names: .postcssrc
(JSON), .postcssrc.js
, or postcss.config.js
.
.postcssrc
config omit.parcelrc
optionminify
. If you use PostCSS config then you need addedcssnano
plugin to minify production build.
.postcssrc
{
"plugins": {
"postcss-import": {},
"autoprefixer": {},
"cssnano": {}
}
}
You can configure how the IDE will parse the files with custom extension.
Add to the root folder of your project a new folder .vscode
