Zasady wizualizacji TypeScript<\/h2>\n

W VPasCode renderowanie TypeScript automatycznie analizuje interfejsy, niestandardowe aliasy typ\u00f3w, granice generyczne, klasy i sk\u0142adowe klas, przekszta\u0142caj\u0105c je w strukturalne wizualne diagramy w stylu UML. Interfejsy i aliasy typ\u00f3w dzia\u0142aj\u0105 jako w\u0119z\u0142y kontrakt\u00f3w strukturalnych, klasy s\u0105 renderowane jako bloki encji z polami typowanymi, a s\u0142owa kluczowe dziedziczenia lub implementacji interfejsu generuj\u0105 jasne po\u0142\u0105czenia relacyjne mi\u0119dzy w\u0119z\u0142ami wizualnymi.<\/p>\n

1. Podstawowa konfiguracja<\/h3>\n

Aby wizualizowa\u0107 standardowy system typ\u00f3w TypeScript, zdefiniuj interfejsy, aliasy typ\u00f3w i klasy implementuj\u0105ce. Standardowe modele domenowe, takie jak konta u\u017cytkownik\u00f3w i role, ilustruj\u0105 podstawowe kontrakty typ\u00f3w i relacje klas:<\/p>\n
