npm install --save gatsby-plugin-compile-es6-packages

or

yarn add gatsby-plugin-compile-es6-packages

Add the plugin to your gatsby-config.js. Specify the npm modules containing ES6 code that require transpilation.

plugins: [
  {
    resolve: `gatsby-plugin-compile-es6-packages`,
    options: {
      modules: [`query-string`]
    }
  }
];

You may also need to use other plugins to handle any specific babel config to transpile the es6 code (i.e. gatsby-plugin-flow)
