NestJS - Database with TypeORM
You want to create a custom method findActiveUsers() in your UserRepository that returns only users with isActive = true. Which approach correctly applies the Repository pattern in NestJS?
AAdd <code>findActiveUsers()</code> method directly in the UserService without modifying repository
BExtend the Repository class and add <code>findActiveUsers()</code> method, then inject this custom repository
CUse a global function outside repository and service to filter active users
DModify the User entity to include a static method <code>findActiveUsers()</code>
Step-by-Step Solution
Solution:
Step 1: Understand extending repository for custom methods
To add custom queries, extend the Repository class and add methods like findActiveUsers().
Step 2: Confirm proper injection of custom repository
Inject the custom repository in services to keep data access logic encapsulated.
Final Answer:
Extend the Repository class and add findActiveUsers() method, then inject this custom repository -> Option B
Quick Check:
Custom repo methods = extend Repository [OK]
Quick Trick:Add custom queries by extending Repository class [OK]
Common Mistakes:
Putting query logic in service instead of repository
Using global functions outside repository pattern
Adding static methods to entity instead of repository
