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 […]
By automating processes, we can ensure that they are performed at the right time and Git hooks can help us with it. Also, with JavaScript, we have a commonly used library called Husky. This article delves into how Git hooks work and how Husky helps us deal with them. The idea behind Git hooks With […]
Sometimes when working with databases, we need to represent a range of values. For example, we might want to define a set of available numbers or a range of dates. One way to do that would be to create two columns that hold the bound values.
1 2 3 4 5 6 | CREATE TABLE events ( id serial PRIMARY KEY, name text, start_date timestamptz, end_date timestamptz ) |
Above, we are using the timestamp with timezone […]
When writing code, we can expect a wide range of errors to happen. We should handle it by writing our code with that in mind. Even though that’s the case, some errors might slip through the cracks. This article looks into what happens with unhandled errors both in Node.js and in the browser. Errors in […]
Handling CPU-intensive operations with REST API can be tricky. If our endpoint takes too much time to respond, it might result in a timeout. In this article, we look into queues to help us resolve this issue. Queue proves to be a very useful part of backend architecture. With it, we can implement asynchronous and distributed […]
We often need to allow our users to perform various delicate operations. They often can’t be undone, which might have dire consequences. Therefore, the good idea is to prompt the user for confirmation. Across our application, the above case might happen frequently. Creating a separate confirmation modal for each of them is far from ideal. […]
We can determine what page the user sees based on the visited URL in a web application with routes. There is more than one way of managing routes with modern single-page applications (SPA). In this article, we look into how hash routing works. We also explain the more modern approach to routing using the history […]
TypeScript is getting more and more popular. Therefore, it is a great time to start using it if you haven’t already. Chances are, our project has been developed for quite some time. If that’s the case, the best approach could be to introduce TypeScript to the codebase gradually. We might encounter a case where we […]
