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:
1
import {getRepository} from "typeorm";
2
import {User} from "./entity/User";
3

4
const userRepository = getRepository(User); // you can also get it via getConnection().getRepository() or getManager().getRepository()
5
const user = await userRepository.findOne(1);
6
user.name = "Umed";
7
await userRepository.save(user);
