Implementing User Authentication With Node JS and PostgreSQL

Hi all,

In this video we are going to be building a Node JS application which will connect to Postgres (SQL) database. The database will be used to store user details including their names, email addresses and passwords in order for them to log on to the application.

We will be using the following Node libraries:

Express - To serve our application
bcrypt - To hash user password to make them secure
express-session - To store session details in a session cookie object
express-flash - To display flash messages to the user
passport - To authenticate users
passport-local - To implement a local authentication strategy for our application

I hope you enjoy the video. Please leave me a comment below if you have any questions.

Thanks guys. If you find this tutorial helpful then please consider subscribing to my channel.

Hi Conor, it seems your video is the best without distracting me from other issues unrelated to auth in the lesson

Great tutorial - easy to follow along, and like some others have said, seeing the debugging is good and keeps knowledge fresh for the viewer. More of these!

Excellent, really helpful and easy to follow! I'm glad you left some mistakes in the video as they gave a chance for me to check my code and find them myself

Did the complete tutorial with you! Worked like a charm! Thank you for sharing this! :)
Ahh quick edit: Since version 0.6.0 req.logout() function is asynchronous. So towards the end, for logout the code should be modified as follows:
```
app.get("/users/logout", (req, res) => {
req.logOut(function(err) {
if (err) { return next(err); }
req.flash("success_msg", "You have successfully logged out.");
res.redirect("/users/login");
});
});
```

Thanks, Conor! I appreciated the way you went step by step and mentioned what you will be doing in each step. It helps a lot to have a logical flow. Cheers! By the way, I also created a Donal Trump account as you did.
