In the last article, we leveraged AWS Cognito to handle user authentication in our application. There was a caveat with the setup, email sharing was allowed. We want to make sure that we only have one user per email. We could build this logic into the sign-up handler in our…

Recently, I posted an article about pre signup triggers for AWS Cognito user pools. The article went over setting up pre signup validation using a lambda function. In this article, I’m going to demonstrate how to achieve the same goal, but using the serverless framework instead of the AWS console…

I’ve written quite a few articles about authentication before. This is yet another user auth article. However, this time, it’s a little different. Previous articles have been about managing user authentication yourself. In this article, we will be leveraging AWS Cognito and its user pools for the same functionality. You…

If you’re building an application, you likely want a lot of users on your platform. However, you don’t just want a large number of users, you want real and high-quality users who will interact with your app. You want to verify those users. It’s common for bots or users with…

No authentication system is complete without a password reset feature. I would personally never ship a product that did not have this feature included. It is necessary to provide a way for users to recover access to their accounts/data in case of a lost or forgotten password. …

In this article, I’m going to demonstrate how to build a user registration and authentication system in ExpressJS. In the previous article, we set up a MongoDB connection using Mongoose. Here we’ll be using that connection to save user data and use it for authentication. This project is available on…

In the previous article, I demonstrated how to set up Nunjucks template engine in your express project. I decided to make this a full-fledged web app development series of articles by progressively building the example application. …

When building a web app without a dedicated front-end framework like ReactJS, Templating engines (e.g. Blade, Nunjucks) are incredibly useful. Though they aren’t entirely necessary, they definitely help create more dynamic pages with cleaner HTML code. Before getting into JavaScript, Flask and Django were my preferred choices for building web…

Cron is a software utility that allows us to schedule tasks (cronjobs) to run periodically, at fixed times or at pre-determined intervals. These tasks can serve any desired function. Some common applications include periodically backing up user data or calling an API endpoint. In this article, I’m going to cover…
