astroturf plugin for Gatsby

This plugin modifies Gatsby's webpack configuration to support astroturf.

Install the plugin and astroturf:

yarn add gatsby-plugin-astroturf astroturf

Add it to your plugins in gatsby-config.js:

plugins: [
  'gatsby-plugin-astroturf',
]

You can also pass options to astroturf's webpack loader:

plugins: [
  {
    resolve: 'gatsby-plugin-astroturf',
    // defaults:
    options: {
      tagName: 'css',
      styledTag: 'styled',
      extension: '.module.css',
    },
  },
]

PostCSS plugins

For astroturf to work properly you need to add nesting support. For that you can use postcss-nested or another plugin which contains this feature, like precss. You can install these plugins and many more using gatsby-plugin-postcss:

yarn add gatsby-plugin-postcss

plugins: [
  'gatsby-plugin-postcss',
  'gatsby-plugin-astroturf',
]

You can specify PostCSS plugins through gatsby-plugin-postcss's postCssPlugins option, or by creating a postcss.config.js file:

yarn add postcss-nested

// postcss.config.js
module.exports =  {
  plugins: {
    'postcss-nested': {},
  }
}

Sass, Less etc.

If you'd like to use Sass, Less or some other preprocessor instead of (or in addition to) PostCSS, make sure that you adjust the extension option and install the appropriate Gatsby plugin. For example, this is all you need to add support for Sass:

yarn add gatsby-plugin-sass

plugins: [
  'gatsby-plugin-sass',
  {
    resolve: 'gatsby-plugin-astroturf',
    options: {
      extension: '.module.scss',
    },
  },
]

Just make sure that your Gatsby plugin supports CSS Modules. Also, note that Sass already has support for nesting, so you don't need postcss-nested.

Happy styling! :art:
