How to run cron job only when making a get request & not everytime we start the server

Question

I want the cron job to get triggered only when we make a get request, it does for the first time, but if I save it will re-run again.

The code does not run whenever the server starts or restarts but as soon as I hit that specefic endpoint, It will run every time the server re-starts.

  startTime = new Date().getTime();
  numberOfMinutes = 10;
  @Cron(CronExpression.EVERY_MINUTE, {
    name: 'myJob',
  })
  async getParisAirQuality() {
    this.logger.verbose(`Getting paris air quality`);
    const result = await this.getCityAirQuality({
      latitude: '48.856613',
      longitude: '2.352222',
    });

    const airQuality = new this.airQualityModel({
      result,
      datetime: new Date().toLocaleString(),
    });
    await airQuality.save();

    this.closeJob();

    return {
      result: airQuality.result,
      datetime: new Date().toLocaleString(),
    };
  }

  closeJob() {
    const job = this.schedulerRegistry.getCronJob('myJob');

    const endTime = this.startTime + 1000 * 60 * Number(this.numberOfMinutes);

    if (job.lastDate().getTime() >= endTime) {
      job.stop();
    }
  }
