Angular — Service va DI
Daraja:
Service — Angular ilovasida biznes logika, HTTP so'rovlar va umumiy holatni saqlash uchun ishlatiladigan @Injectable class. Dependency Injection (DI) esa service va boshqa dependency'larni component'larga avtomatik uzatadi.
Bu bo'limda 20 ta mavzu — service yaratishdan tortib HTTP interceptor, iyerarxik DI, InjectionToken va signal-based store'gacha.
