SyntaxError when builded, can't understand why

Inizia con webpack.config.js e con i punti di ingresso che generano errori, client/pages/Home/index.js e client/index.js, quindi esegui npm start per riprodurre gli errori del parser. Il lavoro è completato quando il JSX di entrambi i file viene compilato correttamente e webpack segnala una build riuscita.
