Section 55.1: Error Handling: GET all resources

How do you handle errors, rather then log them to the console?

• Bad way:

Router.route('/')
  .get((req, res) => {
    Request.find((err, r) => {
      if(err){
        console.log(err)
      } else {
        res.json(r)
      }
    })
  })
  .post((req, res) => {
    const request = new Request({
      type: req.body.type,
      info: req.body.info
    });

    request.info.user = req.user._id;
    console.log("ABOUT TO SAVE REQUEST", request);
    
    request.save((err, r) => {
      if (err) {
        res.json({ message: 'there was an error saving your r' });
      } else {
        res.json(r);
      }
    });
  });

• Better way:

Router.route('/')
  .get((req, res) => {
    Request.find((err, data) => {
      if(err){
        return next(err)
      } else {
        res.json(data);
      }
    })
  })
  .post((req, res) => {
    const request = new Request({
      type: req.body.type,
      info: req.body.info
    });

    request.info.user = req.user._id;
    console.log("ABOUT TO SAVE REQUEST", request);

    request.save((err, data) => {
      if (err) {
        return next(err)
      } else {
        res.json(data);
      }
    });
  });
