I've been trying to implement bcrypt within my user so I can use JWT for authentication; however whenever I try to hash my password with bcrypt it throws and error in the first if statement. I am using the express.js as my framework. I also have to mention that I am not using a database and the user is stored within an array in a different file. I am new to node and I'm still trying to understand it.
My user routes
const express = require('express');
const router = express.Router();
const users = require('../../Users');
const bcrypt = require('bcrypt');
router.post('/signup', (req, res, next) => {
bcrypt.hash(req.body.password, 10, (err, hash) => {
if (err) {
return res.status(500).json({
error: err
});
} else {
const user = {
id: users.length + 1,
userName: req.body.userName,
email: req.body.email,
password: hash,
firstName: req.body.firstName,
lastName: req.body.lastName,
}
user
.then(result => {
console.log(result)
res.status(201).json({
message: 'User created'
})
})
.catch(err => {
console.log(err);
res.status(500).json({
error: err
});
})
}
})
})
Client request
{
"email": "test@test.com",
"password": "testerpassword",
"userName": "test",
"firstName": "teste",
"lastName": "tester"
}
Make a helper method that takes the password and returns and encrypted one:
const crypto = require("crypto");
const hashThePassword = (str) => {
if (typeof str == "string" && str.length > 0) {
const hash = crypto
.createHmac("sha256", config.hashingSecret)
.update(str)
.digest("hex");
return hash;
} else {
return false;
}
};
The config object contains an arbitrary secret string.
