Create USER with bcrypt and authenticate
This is my user.js file, where i handle two requestes.
First the POST /signup, where the user enters an email, and a password so that i can store it in mongodb.
var express = require("express");
const router = express.Router();
const mongoose = require("mongoose");
var bcrypt = require("bcrypt");
var jwt = require("jsonwebtoken");
var User = require("../models/user");
router.post("/signup", (req, res, next) => {
User.find({ email: req.body.email })
.exec()
.then(user => {
if (user.length >= 1) {
return res.status(409).json({
message: "Mail exists"
});
} else {
bcrypt.hash(req.body.password, 10, (err, hash) => {
if (err) {
return res.status(500).json({
error: err
});
} else {
const user = new User({
_id: new mongoose.Types.ObjectId(),
email: req.body.email,
password: hash
});
user
.save()
.then(result => {
console.log(result);
res.status(201).json({
message: "User created"
});
})
.catch(err => {
console.log(err);
res.status(500).json({
error: err
});
});
}
});
}
});
});
Second the POST /login, where the user enters an email, and the password and with bcrypt i compare if the password matches the one in the db.
router.post("/login", (req, res, next) => {
User.find({ email: req.body.email })
.exec()
.then(user => {
if (user.length < 1) {
return res.status(401).json({
message: "Auth failed"
});
}
bcrypt.compare(req.body.password, user[0].password, (err, result) => {
if (err) {
return res.status(401).json({
message: "Auth failed"
});
}
if (result) {
const token = jwt.sign(
{
email: user[0].email,
userId: user[0]._id
},
process.env.JWT_KEY,
{
expiresIn: "1h"
}
);
return res.status(200).json({
message: "Auth successful",
token: token
});
}
res.status(401).json({
message: "Auth failed"
});
});
})
.catch(err => {
console.log(err);
res.status(500).json({
error: err
});
});
});
The problem is the following: Whenever i try to create a user /signup using postman the request stays in "loading" and the server shuts down.
POSTMAN body: {
'emial': 'teste@gmail.com',
'password': '12345'
}
Error in the server:

The User.find promise is being rejected because Node fails to connect to your MongoDB instance. This rejected promise tries to execute the first error handler that it comes across. In your case, it fails to find any catch() to handle this error. You can avoid this by adding a catch() to the promise chain at the end.
You should also look into why your Node instance cannot make a successful connection to your MongoDB instance.
router.post("/signup", (req, res, next) => {
User.find({ email: req.body.email })
.exec()
.then(user => {
if (user.length >= 1) {
return res.status(409).json({
message: "Mail exists"
});
} else {
bcrypt.hash(req.body.password, 10, (err, hash) => {
if (err) {
return res.status(500).json({
error: err
});
} else {
const user = new User({
_id: new mongoose.Types.ObjectId(),
email: req.body.email,
password: hash
});
user
.save()
.then(result => {
console.log(result);
res.status(201).json({
message: "User created"
});
})
.catch(err => {
console.log(err);
res.status(500).json({
error: err
});
});
}
});
}
}).catch(err => { //Handle the error here.
console.log(err);
res.status(500).json({
error: err
});
});
});
You should do the same for your login call.
