使用 try...catch 在 Express 后端正确处理错误

问：

我已经使用 Express 制作后端 API 一段时间了。我最近意识到我大大低估了我需要做的错误处理量，我想在修复我的 API 之前确保我做对了。

下面是一个示例：

router.post('/example', function(req,res,next){
  //try...catch is not needed here because express automatically places routes in a try...catch

  QueryDatabase('SELECT * FROM accounts WHERE uuid = ?', req.session.uuid, (err, result) => {
    //Assuming QueryDatabase uses asychronous callback there needs to be another try...catch in the callback
    if (err) return next(err);
    try {
      let email = result[0].email;

      //Assuming HideEmail uses sychronous callback there does not need to be another try...catch because the outer try catch will catch errors
      HideEmail(email, (err, result) => {
        if (err) return next (err);

        let hiddenEmail = result;

        //Assuming GetVerified uses asychronous callback there still does not need to be try catch because no error could be thrown. 
        //(although maybe one should still be added im not too sure)
        GetVerified(email, (err, result) => {
          if (err) return next (err);

          res.send({email:hiddenEmail, verified:result});
        })
      })
    } catch (error) {
      next(error);
    }
  })
})

这样做并保留我的所有代码都包含在尝试中是个好主意吗？捕获某种内容，当使用异步回调进行另一次尝试时......也抓到？我觉得这是最安全的选择，这样 API 就不会因未处理的错误而崩溃，但我是新手，对我在做什么不太了解。
