postcss-watch-folder

A PostCSS plugin to watch a folder for new files.

Why?

I've had issues when using globs to import stylesheets: @import 'settings/**/*.scss';.

The issues appear when using sass-loader and/or postcss-loader in webpack.

Basically, both SASS and PostCSS do not handle the event of adding files to a watched folder.

This simple plugin solves this issue by watching for add event and updating the main entrypoint.

Dependencies

1. NodeJS
2. NPM or Yarn
3. PostCSS
4. Bash Terminal (Default on OSX/Linux, GitBash on Windows)

Install

npm i postcss postcss-watch-folder --save-dev

or

yarn add postcss postcss-watch-folder --dev

Usage

Webpack:

module.exports = {
  ...
  module: {
    rules: [
      {
        test: /\.css$/,
        use: [
          {
            loader: 'postcss-loader',
            options: {
              plugins: [
                require('postcss-watch-folder')({
                  folder: './your/stylesheets/folder',
                  main: './your/stylesheets/folder/main.css'
                }),
                ...other postcss plugins
              ],
            }
          }
        ]
      }
    ]
  }
}

The location of this plugin does not matter. It can be placed as first or last in the plugins array.

Options

There are two configuration options. They are both required and the plugin will not work if they are not provided:

folder: './assets/styles/',         // The folder to watch
main  : './assets/styles/main.css'  // The main styles entrypoint

Default options are:

folder: '.',           // Current working directory
main  : './style.css'  // style.css located in CWD
