Restful API Design: Best Practices

Obsługa błędów: POBIERZ wszystkie zasoby

Jak radzisz sobie z błędami, a następnie logujesz je do konsoli?

Zła droga:

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);
      }
    });
  });

Lepszy sposób:

Router.route('/')
 .get((req, res) => {
  Request.find((err, r) => {
   if(err){
    console.log(err)
  } else {
    return next(err)
  }
})
})
.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) {
    return next(err)
  } else {
    res.json(r);
  }
});
});
