Over the years, I have been able to adopt an interesting approach to register a user as well as log in the user. Am delighted to share a few decision that has worked for me and I find useful and worthwhile. And I hope to get comments and more insight from you guys to further help me learn and become better. Yes, we are all learning.

What we want to do.

I will assume you have an existing understanding of javascript, node js, express, and MongoDB. we want to set up a platform whereby a user can register as well as login to there account

Main Dependencies

  1. Nodejs must be installed
  2. Mongo DB
  3. Passport
  4. Babel

Overview of dependencies, project structuring.

The src folder contains the source file of the project. the purpose of each of the subfolders will be explained subsequently.

Where we will be starting our development server

On a successful server setup in your console, you should have this logged.

Now that the server is up and running let write some code, let create a register model (create a register.model .js file) and put in the following

Guys, we are still on track now that we have a registered user let create our Login controller and route (create a login.controller.js file)

Editor guide

That's a good example of an Authentication with nodejs and mongoDB, I just use bcrypt to encrypt the password, this way, you don't work with a plain password but only with encrypted passwords.


Can i know your icon and color theme


Hello αвιηαѕн, I use Webstorm IDE (WebStorm Material Theme)


I also use Webstorm but how can I find that icon theme and editor theme?

install Material Theme


Hi Adeeyo, thanks for the post. It will help if you can use code blocks instead of images for your code. This will make it easier for people to copy the code if they want to do so.
