Я пытаюсь использовать библиотеку машинописи, например this , для существующего express nodejs приложения. но это не работает. когда я импортирую библиотечные функции, он выдает ошибки, такие как Cannot read свойство 'constructor' undefined.
Я также компилирую ts-файлы в js -файлы. Есть ли другой способ использовать машинописный текст в существующем node js приложении?
здесь стек ошибок
