NestJS is a framework for building Node.js applications. It is somewhat opinionated and forces us to follow its vision of how an application should look like to some extent. That might be viewed as a good thing that helps us to keep consistency across our application and forces us to follow good practices. NestJS uses Express.js […]
Branches are the bread and butter of a software developer using a Version Control System (VCS) of any kind. Today we explore how they work in Git. In the previous part of this series, we’ve learned that a commit is a full snapshot of the project state. In Git, the branch is a pointer to a […]
When we develop a REST API, we have a set of HTTP methods that we can choose. An important thing to understand is that HTTP methods are, to a large extent, indicators of actions. Therefore, it is our job to make them work properly. In theory, not much stops us, for example, from deleting entities with […]
Mongoose does quite a bit of heavy-lifting for us. It is immensely useful, but not necessary in every case. In this article, we explore the Mongoose documents more and learn what we can achieve by giving up their benefits. Mongoose Document In the second part of this series, we’ve created our first models. They allow […]
As a developer, there is a high chance that you use Git every day. It means saving changes through commits. In this article, we look into what are their building blocks. This includes looking into the filesystem of Git and learning about different states of files. Git is a Distributed Version Control System To understand what […]
Version control systems (VCS) are one of the essential tools of every programmer. The most popular one is Git, and therefore it is worth looking into it a bit more. In this article, we look into what is a remote and what the origin keyword means. We also check out what is an upstream branch and how we can benefit […]
The Formik library keeps on growing and attempts to keep up with the React community. Formik, since version 2.0, has a built-in set of hooks. In this article, we go through all of them. We also look into how to use Formik with TypeScript. The basics of Formik with TypeScript Form handling in React might […]
The immutability is quite a buzzword lately. Today we attempt to find out why. In this article, we explain what the immutability is and how we can benefit from it. When defining immutability, we look into various aspects of it. We investigate primitive values, assignment immutability, and how to keep our data structures immutable. We also look […]
TypeScript works in a way that automates a lot of the work for us. We don’t have to write types every time, because the compiler works hard to derive them from the context. In this article, we look into more complex cases that involve the infer keyword and const assertions. The basics of type inference First, let’s look […]
One of the qualities of our code that we should aim for is reusability. Also, following the Don’t Repeat Yourself principle makes our code more elegant. In this article, we explore writing functional React components with TypeScript using generic props. By doing so, we can create reusable and flexible components. If you would like to […]
