Amfani Dependency Injection Design Pattern da in Node.js
Ƙirƙirar da Amfani da Dogara: Don amfani da DI a cikin Node.js, kuna buƙatar samar da abin dogaro lokacin ƙirƙirar abubuwa:
class DatabaseService {
constructor(databaseConnection) {
this.db = databaseConnection;
}
// Methods using the database connection
}
const databaseConnection = //... Initialize the database connection
const databaseService = new DatabaseService(databaseConnection);
