So far, in this series, we’ve focused on working with SQL and the Postgres database. While PostgreSQL is an excellent choice, it is worth checking out the alternatives. In this article, we learn about how MongoDB works and how it differs from SQL databases. We also create a simple application with MongoDB and NestJS. You […]
An important part of designing a database is controlling the data we store inside. The most fundamental way of doing that is defining the types for our columns. With that, we can make sure that a particular column holds only text, for example. In this article, we use constraints to have even more control of […]
Authenticating users with emails and passwords is a valid and common approach. However, a convenient alternative is to shift this responsibility to a third party. In this article, we look into adding Google authentication to a NestJS project. We can achieve the above because Google uses the OAuth (Open Authorization) framework. With it, Google users […]
In our web applications, we often need to send messages to our users. Doing that through email is enough in a lot of cases, but we can also use SMS. In this article, we look into how we can use Twilio for verifying phone numbers provided by our users and sending messages. Setting up Twilio […]
In a lot of web applications, emails play a significant role. If we create an online ordering system, we need to be confident that our users get a confirmation email. When our services include a mailing list, we want to make sure that the provided email is valid. We also might want to implement the […]
So far, in this series, we’ve interacted with Stripe by sending requests. It was either by requesting the Stripe API directly on the frontend, or the backend.

In this series, we’ve implemented a few different ways of charging our users using Stripe. So far, all of those cases have included single payments. With Stripe, we can also set up recurring payments using subscriptions. Recurring payments are a popular approach nowadays in many businesses. The users save a credit card and get billed […]
With Stripe, we can build advanced custom payment flows. In this article, we continue looking into it and save credit cards for future use. To do that, we need to have a more thorough understanding of how we can integrate Stripe with our system. Saving cards with setup intents Our goal in this article is […]
Nowadays, a lot of web applications accept online payments. Although this is not straightforward to implement, there are some ready-to-use solutions that we can take advantage of. In this article, we look into Stripe. It serves as a payment processing platform that does the heavy lifting for us. To implement it, we use NestJS and […]
So far, in this series, we’ve used JSON Web Tokens (JWT) to implement authentication. While this is a fitting choice for many applications, this is not the only choice out there. In this article, we look into server-side sessions and implement them with NestJS. You can find the code from this article in this repository […]
