我将 typeorm 与 nativescript 应用程序一起使用。当我将数据更新到本地数据库时，我希望运行一个计时器。所以我在调用entitymanager.save之前启动计时器。计时器运行 1 - 2 秒...冻结..然后在查询完成后继续运行。

这样做的目的是，当用户等待更新插入完成时，我可以在主屏幕上显示或隐藏图标。

有没有办法让计时器在 typeorm 执行任务时继续运行？

我尝试过 1. 将 .save 方法包装在可观察对象中。2. 将计时器包装在 Promise 中

public uploadAllCodes() {
  let intervalId = setInterval(() => {
  this.counter = this.counter + 1;
  console.log(this.counter);
    if (this.counter === 25) {
      clearInterval(intervalId);
    }
  }, 1000);


  try {
    await this.Upsert(Codes, this.codes);
  } catch (e) {
    await alert(e);
  }

}

static async Upsert(EntityType: any, Entity: any) {
        let databaseConnection = await this.GetDatabaseConnection();

        await databaseConnection.manager.transaction(async manager => {
            await manager.save(EntityType, Entity, {
                listeners: …

        for (int i = 0; i < 7; i++)
