AlminとFB FluxやReduxの違い?

Almin

最低限のコンポーネントを並べると他のライブラリとあまり変わらないです。ただレイヤーを意識して実装してみると、他のライブラリのチュートリアル通りの実装比較では実装量が増えると思います。ただし、その場合も増えているのはAlminに依存した部分ではなく、自分で実装しないといけないDomainやInfra(Repository)などといったレイヤーになります。これは責務をレイヤーで分離する考え方から来ているので、他のライブラリでも同じようなレイヤーを実装すると同じようにコード量が増えると思います。(登場人物が多く見える)

	// This is an example knex migration file for said behavior.
