TypeScript项目中的TypeORM应该如何配置才能在任何地方运行？

npm install typeorm reflect-metadata mysql

{
  "type": "mysql",
  "host": "数据库主机地址",
  "port": 3306,
  "username": "数据库用户名",
  "password": "数据库密码",
  "database": "数据库名",
  "synchronize": true,
  "logging": true,
  "entities": [
    "src/entities/**/*.ts"
  ],
  "migrations": [
    "src/migrations/**/*.ts"
  ],
  "subscribers": [
    "src/subscribers/**/*.ts"
  ],
  "cli": {
    "entitiesDir": "src/entities",
    "migrationsDir": "src/migrations",
    "subscribersDir": "src/subscribers"
  }
}

import { Entity, Column, PrimaryGeneratedColumn } from "typeorm";

@Entity()
export class User {
  @PrimaryGeneratedColumn()
  id: number;

  @Column()
  name: string;

  @Column()
  age: number;
}

npx typeorm migration:run

import { getRepository } from "typeorm";
import { User } from "../entities/User";

class UserService {
  private userRepository = getRepository(User);

  async createUser(name: string, age: number): Promise<User> {
    const user = new User();
    user.name = name;
    user.age = age;
    return this.userRepository.save(user);
  }

  async getUsers(): Promise<User[]> {
    return this.userRepository.find();
  }
}
