Package Exports

@snowpack/plugin-postcss

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@snowpack/plugin-postcss) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

@snowpack/plugin-postcss

Run PostCSS on all .css files, including ones generated from Sass, Vue, and Svelte.

Usage

From a terminal, run the following:

npm install --save-dev @snowpack/plugin-postcss postcss postcss-cli

Then add this plugin to your Snowpack config:

// snowpack.config.json
{
  "plugins": [
    "@snowpack/plugin-postcss"
  ]
}

Lastly, add a postcss.config.js file to the root of your project as you would normally:

const cssnano = require('cssnano');
const postcssPresetEnv = require('postcss-preset-env');

module.exports = {
  plugins: [cssnano(), postcssPresetEnv()],
};

Plugin Options

Name	Type	Description
`input`	`string[]`	File extensions to transform (default: `['.css']`)
`config`	`string`	(optional) Set a custom path to your PostCSS config (in case PostCSS has trouble loading it automatically, or in case you want multiple PostCSS setups)
