How to Use

gatsby-config.js

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

module.exports = () => ({
  plugins: [
    postcssPresetEnv({
      stage: 0
    })
  ]
});

Options

You can use any allowed postcss-loader options using postcss property:

gatsby-config.js

module.exports = {
  plugins: [
    {
      resolve: 'gatsby-plugin-postcss',
      options: {
        postcss: {
          plugins: () => [require('postcss-preset-env')({ stage: 0 })]
        }
      }
    }
  ]
};
