What is Repository
Repository is just like EntityManager but its operations are limited to a concrete entity.
You can access repository via getRepository(Entity),
Connection#getRepository, or EntityManager#getRepository.
Example:
import {getRepository} from "typeorm";
import {User} from "./entity/User";
const userRepository = getRepository(User); // you can also get it via getConnection().getRepository() or getManager().getRepository()
const user = await userRepository.findOne(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.
