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 […]
As applications grow, the number of different entities also increases. A crucial part of learning how to design a database is creating relationships between them. This is because our entities will often relate to each other in some way. Relational databases such as PostgreSQL are an industry standard for quite some time now. Although there […]
So far, in this series, we’ve been using TypeORM to manage our data and connect to our Postgres database. In this article, we look into Prisma, which is a capable alternative. With Prisma, we describe our data using a Prisma schema file. It uses its own data modeling language and acts as a single source […]
In the previous article, we’ve looked into various ways to store the date and time with PostgreSQL and TypeORM. Postgres can also manage intervals. With them, we can store a period of time. Ways to store and display intervals in PostgreSQL There are various ways we can input and view interval values. By default, PostgresSQL represents […]
While dealing with data, we often have to handle the date and the time. When doing so, there are quite a few things to consider. In this article, we approach various issues both from the standpoint of PostgreSQL and TypeORM. Ways to store and display date and time in PostgreSQL By default, Postgres represents dates […]
While developing our application, security should be one of our main concerns. One of the ways we can improve it is by implementing a two-factor authentication mechanism. This article goes through its principles and puts them into practice with NestJS and Google Authenticator. Adding two-factor authentication The core idea behind two-factor authentication is to confirm […]
