Es ist nicht Webpack Overhead. Dieser Overhead wurde durch einen anderen Grund verursacht. Hier demonstrieren Sie die Webpack-Konfiguration. Das Webpack erstellt das Paket für die Quelle mit dem Inhalt alert() mit einer Ergebnisgröße von nur 519 Bytes anstelle von 96kb, die in Frage gestellt wurden. Das Projekt Inhalt und Ergebnis Bündel (minimierte und Non minified) ist:

Können Sie uns Ihre Webpack-Konfiguration zur Verfügung stellen? Es sieht so aus, als ob da etwas drin ist, das die große Menge an Overhead verursacht, die du siehst. – Ambroos
Haben Sie eine Antwort darauf gefunden? Ich habe ein Kopfgeld eröffnet, weil ich genau das gleiche Problem habe. – dccarmo
