Authentication in NodeJS - REST API with NodeJS and MySQL (2020)

Today we're gonna learn how implement Authentication in NodeJS. So, we'll be creating User Signup and User Login with Token based Authentication.

0:00 Intro
1:15 Install Bcryptjs, JsonWebToken, and Nodemon
4:12 Implement User Signup
13:49 Implement password Hashing
18:08 Implement Duplicate email check
22:37 Implement User Login
27:10 Generating access token
34:43 Setup Nodemon
36:39 Outro

In the previous video we implemented Requests Data Validations.

Here in this video we learn how to implement Token based Authentication in NodeJS. So, we'll add Signup functionality and the Login functionality.

Download project files.

So, that's how can implement Authentication in NodeJS.

Then finally we setup Nodemon in our project. That's a development dependency. Currently each time we make a change, we have to restart the server. This can be a pain in the neck while developing. So, once Nodemon is setup, it's watching for the changes in the code and automatically restart the NodeJS server for us. So, that's a plus for the productivity.

In the next tutorial we'll learn about Middlewares

Where implement duplicate email check,
you should have explained what is model user and how to make it.
I've seen your project code. There are few unexplained dependencies used for making user Model.

u teach very well, can you make more videos on nodeJs

[manuelsilva]

Hey, have you ever tried it with directus (headless cms)? I'm using this API and the folders (and path to them) are different, so this way is a bit hard to understand the procedure.
There aren't many videos about directus (maybe it would be a nice oportunity to approach this theme ahaha), if you are familiar with it, can you make some vids about it?

Anyway, thanks for the tutorial!

Great content. A quick one. Where you create a token, what you send is only the token yet the variable you define as token has everything such as email and the token its self. How can I use the const token so that getting the user's email from the token is straightforward? I hope am clear!
const token = jwt.sign({
username: user.username,
userId: user.id
}, process.env.JWT_KEY, function(err, token){
res.send(200).json({
message: "Authentication successful!",
token: token,

});
