How do I make the user repository use the extends property?

Question

I’m trying to make a generic repository, I’m using Mongodb for that, I tried to import it and use it with the property extends other classes, but did not succeed.

What I need is to make the class available Repository for all application controllers, and all features that require access to the database must be able to connect to the repository.

In this scenario what I tried:

// userSchema.js
const UserSchema = new mongoose.Schema({
  name: {
    type: String,
    required: true
  }
});


const User = mongoose.model('User', UserSchema);

module.exports = User;


// repository.js
class Repository {
    constructor(dbCollection) {
      this.dbCollection = dbCollection;
    }

    get(_id) {
        return this.dbCollection.findById({ _id });
    }
}

module.exports = Repository;

// user.repository.js
const Repository = require('./repository');

class UserRepository extends Repository {
  constructor(user) {
    super({
      dbCollection: user
    });
  }
}

module.exports = UserRepository;

// UserController.js

const UserRepository = require('./user.repository.js');

class UserController {
    async find(req, res) {
        const user = await UserRepository.get(req.params.id);
        return res.status(200).json(user);       
    }
}
module.exports = new UserController();

// mongo.js
const mongoose = require('mongoose');

const connectionOptions = {
  useNewUrlParser: true,
  useFindAndModify: false
};

class Database {
  constructor() {
    this.connect();
  }

  connect() {
    return mongoose.connect(process.env.MONGO_URL, connectionOptions);
  }
}

module.exports = new Database();

I also tried on the controller something like:

const UserRepository = require('./user.repository.js');
    const schemaUser = require('./schemaUser');

    class UserController {
        async find(req, res) {
            const test = new UserRepository(schemaUser)
            const user = await test.get(req.params.id);
            return res.status(200).json(user);       
        }
    }
    module.exports = new UserController();

In both cases without success. Like to do something similar to injection of dependencies.

You don’t have a class error:

class UserRepository extends Repository {
   constructor(user) {
     super({
       dbCollection: user
     });
   }
}

In the super these to pass an object should not only pass the user directly? IE:

class UserRepository extends Repository {
    constructor(user) {
      super(user);
    }
}
