itmar-block-packages/webpack.config.js

We have put together a package of common React components used for WordPress custom blocks.

const defaultConfig = require("@wordpress/scripts/config/webpack.config");

// オリジナルをカスタマイズ
module.exports = {
  ...defaultConfig,
  output: {
    ...defaultConfig.output,
    libraryTarget: "commonjs2",
  },
};
