What is Repository

Repository is just like EntityManager but its operations are limited to a concrete entity. You can access the repository via EntityManager.
Example:
import { User } from "./entity/User"
​
const userRepository = dataSource.getRepository(User)
const user = await userRepository.findOneBy({
    id: 1,
})
user.name = "Umed"
await userRepository.save(user)
There are 3 types of repositories:
Repository - Regular repository for any entity.
TreeRepository - Repository, extensions of Repository used for tree-entities (like entities marked with @Tree decorator). Has special methods to work with tree structures.
MongoRepository - Repository with special functions used only with MongoDB.
