NodeJS - timeout on large file download

Question

I am trying to download a fairly large file (500MB) from an NodeJS API endpoint, but the following code appears times out with a 504 Gateway Timeout:

  async download(res: Response) {
    const path = `${this.EXCEL_SAVE_DIR}/report.xlsx`;
    try {
      if (fs.existsSync(path)) {
        res.download(path);
      } else {
        logger.debug(`download -> file not found at: ${path} `);
      }
    } catch (err) {
      logger.debug(`download -> error: ${JSON.stringify(err)}`);
    }
  }

Is it possible to avoid these timeouts?

is there any services of apache or nginx running ? have you checked from where 504 is returning? is it before hitting node server? — sojin, Jan 28 '22 at 15:48
I've got nginx service running on there. The 504 returns when I hit the download api endpoint which calls the above code to download the 500MB file. — methuselah, Jan 28 '22 at 15:50
SO error must be from nginx you can configure the max time limit in nginx — sojin, Jan 28 '22 at 15:51

It is due to the max time limit settings in nginx, change it in config — sojin, Jan 28 '22 at 15:53
