WebPack-DevServerのバグの対応

Posted at

詳しいことはよくわからないがDevServerでホットリロードできなくなる問題がある模様

解決法

configのtargetをwebに書き換える

webpack.config.js

module.exports={
...
target:"web" //ふつうは["web","es5"]とかかな?
...
}

けどこの方法だと、ビルドするときに戻さないといけなくなる

解決法改

ドキュメントによると
オブジェクトの代わりに関数をエクスポートすると、実行時のモードによって
動作を変更できるらしい

webpack.config.js
const config ={
...
}
module.exports = (env, argv) => {
  if (argv.mode !== 'production') {
    config.target = 'web';
  }
  return config;
};

これでおそらくは大丈夫と思う
