Tell the user when there has been a server error

[helenzhou6]

In logic.js

ToVaHayGi/public/logic.js

Lines 12 to 14 in 4b3cf6e

	} else {
	console.log("XHR error", xhr.status);
	}

• I would change your callback functions (such as setStorage()) to become error first and display it to the user.

In handler.js:

ToVaHayGi/src/handler.js

Lines 148 to 149 in 4b3cf6e

	bcrypt.genSalt(10, (err, salt) => {
	if (err) console.log(err);

ToVaHayGi/src/handler.js

Lines 39 to 41 in 4b3cf6e

	if (err || !decoded) {
	// if not logged in
	console.log(err);

In addition console.log(error), may I suggest also sending something back to the user (like you have done for some others) e.g.:

      res.writeHead(500, 'Content-Type:text/html');
      res.end('<h1>Sorry, there was a problem on our side<h1>');

Since you'll be using this multiple times, perhaps have it has a function that you re-use (with an argument if you wanted to pass in a custom message).
