@adrien2p Is this ready for review?

[adrien2p]

@olivermrbl I did not test it yet, i ll do that tomorrow morning

[adrien2p]

@olivermrbl I ve just tested it and it worked

// src/repositories/user-test.ts

import { dataSource } from "@medusajs/medusa/dist/loaders/database";
import { User } from "@medusajs/medusa";

const UserRepository = dataSource.getRepository(User).extend({
  test() {
    return { test: "test" }
  }
})

export default UserRepository

and in the API directory

  route.get('/test', async (req, res) => {
    const userTestRepo = req.scope.resolve("userTestRepository")
    const test = userTestRepo.test()
    res.json(test)
  })

I have also tested to override an existing repo

// src/repositories/user.ts

import UserRepository from "@medusajs/medusa/dist/repositories/user";

const UserRepo = UserRepository.extend({
  test() {
    return { test: "test" }
  }
})

export default UserRepo

and in the API

  route.get('/test', async (req, res) => {
    const userTestRepo = req.scope.resolve("userTestRepository")
    const test = userTestRepo.test()

    const userRepo = req.scope.resolve("userRepository")
    const test2 = userRepo.test()

    res.json([test, test2])
  })

LGTM, we could add an integration test :)
