NestJS Abstract Repository Pattern

The Abstract Repository pattern decouples the business logic from the data layer. Consider the scenario that we have created all of our end points, only to discover that our ORM is making suboptimal queries. All of our services would be coupled to TypeORM's unique methods. Switching to another ORM would require us to manually change all of those methods. The Abstract Repository pattern solves this issue by having the ORM specific operations in an abstract repository that our specific entities can extend. Thus, changes can be made in just one file, without worrying about needing to update our entire code base. -------------------------------------------------- Recommended Udemy courses -------------------------------------------------- NestJS - Zero to Hero: https://tinyurl.com/3rxsz669 React - The Complete Guide: https://tinyurl.com/2t6v5yeu Angular - The Complete Guide: https://tinyurl.com/4h5rmpsj React Native - The Practical Guide: https://tinyurl.com/3wzmdzht Docker Mastery (with Kubernetes + Swarm): https://tinyurl.com/yeymdnhn NestJS API code: https://github.com/Jon-Peppinck/messe...
