Note: Please don't use this for production. This library is still in heavy development and experimental. I want to improve this library before becoming production-ready.

どのように私のライブラリを呼び出すには？

• Promise then/catch

import featureFlag from '@berviantoleo/feature-flag';

featureFlag('try_feature_flag').then((result) => {
  console.log(result);
});

あなたもasync/awaitアプローチを使用することができます.

例の出力

feature-flag

Welcome to contribute to my small library/project. :) If you have any inputs, feel free to add them here too.

次は何ですか。

私は同様のライブラリ/プロジェクトを作成するつもりです.ネットそれで、調整されてください!

ありがとう
