  clients: {
    // clientId, access the client instance by app.mongooseDB.get('clientId')
    db1: {
      url: "mongodb://127.0.0.1/example1",

  const mongoose = app.mongoose;
  const Schema = mongoose.Schema;
  const conn = app.mymongoose.get("db1");

  const UserSchema = new Schema({
    userName: { type: String },
    password: { type: String }

  return conn.model("User", UserSchema);
};

// {app_root}/app/mymongoose/model/book.js
module.exports = app => {
